Oklahoma Tax Breach and FBI Impersonation Scam: This Week in Scams

3 April 2026 at 11:01
Suspects wanted by the FBI

A tax system breach in Oklahoma is putting highly sensitive personal information at risk. And unfortunately, this is exactly the kind of situation scammers love to exploit. 

Hackers reportedly accessed W-2 and 1099 files through Oklahoma’s online tax portal, according to state officials, exposing the kind of information that can open the door to tax fraud, identity theft, and highly targeted phishing attempts. 

Before the follow-up scams start rolling in, this is the kind of moment where layered protection matters. McAfee+ Advanced includes identity monitoring and data cleansup that can help alert you if your personal information starts circulating where it shouldn’t, and Scam Detector can flag suspicious messages if scammers try to use this breach as a hook. 

What Happened in Oklahoma 

According to a statement by the Oklahoma Tax Commission and reported by KOCO News 5, a local ABC affiliate, suspicious activity inside the state’s Oklahoma Taxpayer Access Point system was identified in December 2025. The agency says impacted individuals have been notified directly by mail, and complimentary credit monitoring and fraud assistance are being offered. 

When W-2s, 1099s, Social Security numbers, and tax-related records are exposed, scammers can use that information to: 

  • File fraudulent tax returns  
  • Try to open new accounts  
  • Build phishing emails or texts that feel unusually real  

Either way, the goal is the same: use real information to make the next scam more believable. 

Red Flags of a Scam After a Breach Like This 

The breach itself is real. But what often follows is a second wave of scams pretending to help. 

Watch For: 

  • Emails or texts about your “tax account” that create urgency  
  • Messages asking you to verify personal information  
  • Fake alerts about refunds, filings, or suspicious activity  
  • Links telling you to log in and “secure” your account  

That’s where people can get hit twice: once by the breach, and again by the scam that follows it. 

What To Do If You’re Impacted 

First, don’t panic. Then: 

  • Take advantage of any free credit monitoring or fraud assistance being offered  
  • Monitor your bank accounts, tax records, and credit reports closely  
  • Consider placing a fraud alert or credit freeze if needed  
  • Be extra careful with any message referencing taxes, refunds, or account access 
  • Go directly to official sites instead of clicking links in emails or texts  

And that, my friends, is scam number one in this week’s This Week in Scams. 

Let’s get into what else is on our radar. 

The FBI Impersonation Scam Showing Up Across the U.S. 

Scammers pretending to be federal agents are making the rounds across the country, and this one is built to make people panic fast. 

Field offices, including Chicago and Houston, are warning the public about fraudsters posing as FBI agents in calls, texts, and emails. In some cases, the scammers claim you’re connected to an investigation. In others, they say you’re a victim of fraud and need to act immediately to protect yourself. 

Sometimes they do not stop there. They may also pretend to be bank employees working alongside the FBI, all to make the story feel more convincing and get access to your money or personal information. 

Suspects wanted by the FBI
The FBI has shared images of these suspects pretending to be agents. If you are contacted by these officials, report it to the FBI.

Why This Scam Works

This scam plays on the same pressure tactics we’ve seen over and over again: authority, urgency, and confusion. 

If someone claims to be a federal agent, many people freeze up and assume they need to cooperate immediately. That’s exactly what scammers are counting on. 

The FBI has been clear about this: federal law enforcement will not ask you for money or sensitive personal information over the phone, by text, or by email. 

The Red Flags in This Message

  • Unsolicited outreach from someone claiming to be federal law enforcement  
  • Pressure to act immediately  
  • Requests for money, gift cards, prepaid cards, or personal information  
  • Instructions to keep the conversation secret  
  • Stories involving a bank “working with” the FBI  

If it feels dramatic, high-pressure, and just a little off, trust that instinct. 

What To Do if You Get One Of These Messages

  • Do not respond  
  • Do not send money or share personal information  
  • Contact the agency directly using publicly listed contact information  
  • Save the message for your records  
  • Report it to the FBI: 1-800-CALL-FBI (225-5324), or online at tips.fbi.gov.

This is also exactly the kind of message McAfee’s Scam Detector is built to flag before you get pulled in. 

How McAfee Helps You Stay Ahead of Scams and Breaches 

McAfee+ Advanced gives you multiple layers working together so you are not left figuring it out after the damage is done: 

  • Identity Monitoring alerts you if your personal info shows up where it should not, so you can act fast
  • Personal Data Cleanup helps remove your information from data broker sites, making you harder to target in the first place
  • Scam Detector flags suspicious texts, emails, links, and even deepfake videos before you engage
  • Safe Browsing helps block risky sites if you do click
  • Device Security helps detect malicious apps or downloads
  • Secure VPN keeps your data private, especially on public Wi-Fi  

This kind of layered protection is critical in cases like ghost student scams, where the first sign of fraud often comes after financial damage has already happened. 

Safety tips to carry into next week 

  • Be extra cautious after any real breach makes headlines  
  • Do not trust unsolicited messages just because they reference real institutions  
  • Never send money to someone claiming to be law enforcement  
  • Go directly to official websites instead of clicking links  
  • Use tools that flag suspicious messages in real time so you do not have to guess 

The reality is, scams are getting better at looking official. 

You should not have to be an expert to spot them. That’s why McAfee is here to help. We’re Safer Together.

We’ll be back next week with more scams making headlines.

McAfee’s “Keep It Real” Campaign Named Shorty Awards Finalist

2 April 2026 at 11:00

We’re proud to share that McAfee’s “Keep It Real” campaign has been named a finalist in the 2026 Shorty Awards Social Good Campaign category. 

This category recognizes work that doesn’t just perform, it matters: campaigns that raise awareness, inspire action, and make a real-world impact. 

That’s exactly what “Keep It Real” set out to do. 

Because behind every scam statistic is a person who thought they were making the right call. And too often, what follows isn’t just financial loss. It’s embarrassment, silence, and stigma. 

We wanted to change that. 

The campaign launched alongside McAfee Scam Detector to address a growing reality: scams powered by AI are becoming harder to recognize and easier to fall for. 

“Keep It Real” paired real survivor stories with AI-driven protection to show how scams actually happen and how people can stop them in the moment. 

The goal was simple: 

  • Normalize the experience  
  • Remove shame around being scammed 
  • Help more people recognize scams faster  

Because when people feel safe talking about scams, they’re more likely to spot them and stop them. 

What Are the Shorty Awards? 

The Shorty Awards honor the best work in social media, digital campaigns, and online storytelling across brands, creators, and organizations. 

Now in their 18th year, the awards recognize campaigns that combine creativity, impact, and real-world relevance. Finalists are selected alongside leading global brands and judged on both industry evaluation and public voting. 

How McAfee’s Scam Detector Fits In 

McAfee’s Scam Detector is designed to help people identify scams across everyday digital moments. 

It uses AI to fight AI by flagging suspicious: 

  • Text messages and emails  
  • QR codes and links  
  • Social media messages  
  • AI-generated and deepfake content  

By combining automatic detection with clear guidance, Scam Detector helps people better understand what they’re seeing and decide what to trust. 

Real Stories Behind the Campaign 

A core part of “Keep It Real” was giving space to people who experienced scams to share what happened, in their own words. 

These stories helped show that scams can happen to anyone and played a key role in breaking the stigma around being targeted. 

 

This recognition reflects the work across McAfee teams who built and brought this campaign to life, including product, engineering, research, creative, and communications. 

It also reflects the individuals who chose to share their real scam stories to help others recognize scams, stay safer, and end the shame and stigma around being scammed.

Operation NoVoice: Android Malware Found in 50+ Apps Can Hijack Devices

31 March 2026 at 10:00

McAfee’s mobile research team has uncovered a large-scale Android malware campaign we’re tracking as Operation NoVoice.

The campaign was distributed through more than 50 apps previously available on Google Play, disguised as everyday tools like cleaners, games, and photo utilities. Together, the apps were downloaded more than 2.3 million times, though it’s unclear how many devices may have been impacted.

If the attack succeeds, the malware can gain deep control of a device, allowing attackers to inject malicious code into apps as they are opened and access sensitive data.

However, the most serious impact depends on the device. 

On older or unpatched Android devices, the malware can install a highly persistent form of infection that may survive a standard factory reset. Newer Android devices with up-to-date security protections are not vulnerable to the root exploit observed in this campaign, though they may still be exposed to other types of malicious activity from these apps.

In other words, on vulnerable devices, the malware can behave like a kind of digital “zombie,” continuing to operate in the background even after a reset.

Want the full technical breakdown? Dive into the McAfee Labs research here. 

We break down what you need to know below: 

How “Operation NoVoice” Works 

Operation NoVoice is what security experts call a rootkit malware attack. 

rootkit is a type of malware designed to gain deep, privileged control of a device while hiding its presence from the user and the operating system’s normal security tools. 

Breaking the term down: 

  • “Root” refers to the highest level of access on a system (administrator-level control). 
  • “Kit” refers to a collection of tools used by an attacker to maintain that control. 

Put simply, a rootkit allows attackers to operate underneath the normal apps and security protections on a phone, giving them powerful control while staying difficult to detect.

In the case of Operation NoVoice, the attack unfolds in several steps. 

1) A normal-looking app starts the attack

The campaign began with apps that appeared harmless on the Google Play Store. These apps advertised themselves as tools like phone cleaners, puzzle games, or gallery utilities. 

When a user downloaded and opened one of these apps, it appeared to work normally. There are no obvious signs to the user that anything is wrong. 

2) The malware quietly checks the device

Behind the scenes, the app contacts a remote server controlled by the attackers. 

The server collects information about the device, things like its hardware, operating system version, and security patch level. Based on that information, the attackers send back custom exploit code designed for that specific device.

3) The attack gains deep system access

If the exploit succeeds, the malware gains root-level access to the device.

At that point, the attackers can install additional malicious components and modify parts of the Android operating system itself. 

4) Every app on the phone can be affected

Once the rootkit is installed, it modifies a core Android system library that every app relies on. 

This allows attacker-controlled code to run inside any app the user opens. 

That means the attackers could potentially access data from messaging apps, financial apps, or social media apps without the user noticing. 

5) The malware can remain even after a reset

Operation NoVoice also includes persistence mechanisms designed to keep the malware active. 

In some cases, the infection could survive a standard factory reset, because the malicious components modify parts of the system software that resets typically do not replace.

Fully removing the infection may require reinstalling the device’s firmware, something most users cannot easily do themselves.

*To be clear, these apps have been removed from Google Play and are no longer available for download. 

Why The Name “Operation NoVoice” 

The name Operation NoVoice comes from a hidden component inside the malware itself. 

Researchers discovered a resource labeled “novioce” embedded in one of the attack’s later stages. The file contains a silent audio track that plays at zero volume. 

This may seem strange, but it serves a purpose. 

By continuously playing silent audio in the background, the malware can keep a foreground service running without drawing attention. This allows the malicious code to remain active while appearing harmless to the operating system. 

The researchers believe the name “novioce” is likely a misspelling of “no voice,” referring to the silent audio trick used to keep the malware running. 

How To Stay Safe from Malware Disguised as Apps 

Operation NoVoice highlights an important reality: even apps that appear legitimate can sometimes hide malicious behavior. 

Fortunately, there are several steps users can take to reduce their risk. 

Be cautious with unfamiliar apps 

Even if an app appears on the Google Play Store, it’s still important to review: 

  • the developer’s name 
  • the number of downloads 
  • recent user reviews (check for negative reviews) 

Apps with very few reviews, vague descriptions, or suspicious developer accounts can sometimes be part of malware campaigns. And exercise even greater caution with apps promoted through advertisements or that create a a sense of urgency.  

Keep your phone updated 

Many attacks rely on exploiting known vulnerabilities in older versions of Android. 

Installing system updates and security patches helps reduce the chance that these exploits will work.

Remove apps you don’t recognize 

If you notice apps on your device that you don’t remember installing, review them carefully and remove anything suspicious. 

Keeping your phone’s app list clean reduces the potential attack surface. 

Use mobile security protection 

Mobile security software can help detect suspicious behavior and block known malware. 

For example, McAfee Mobile Security detects this threat as Android/NoVoice and can warn users if a malicious app is identified.  

McAfee offers more than traditional antivirus, combining multiple layers of digital protection in one app  

What Operation NoVoice Tells Us About the Future of Mobile Threats 

Operation NoVoice highlights how mobile malware is evolving. Instead of obvious malicious apps, attackers are increasingly hiding their operations inside ordinary-looking tools distributed through legitimate app stores.

What makes this campaign particularly concerning isn’t just the number of downloads or the technical complexity. It’s the way the malware combines several advanced techniques, device-specific exploits, modular plugins, and deep system persistence, into a single attack chain.

That approach allows attackers to quietly turn an everyday app download into long-term control of a device.

That’s why keeping devices updated, reviewing apps carefully, and using mobile security protection are becoming increasingly important. As Operation NoVoice shows, today’s malware isn’t just trying to get onto devices; it’s trying to stay there.

Operation NoVoice: Rootkit Tells No Tales

31 March 2026 at 09:30

Authored By: Ahmad Zubair Zahid 

McAfee’s mobile research team identified and investigated an Android rootkit campaign tracked as Operation Novoice. The malware described in this blog relies on vulnerabilities Android made patches available for in 2016 – 2021. All Android devices with a security patch level of 2021-05-01 or higher are not susceptible to the exploits that we were able to obtain from the command-and-control server. However patched devices that downloaded these apps could have been exposed to unknown potential payloads outside of what we discovered. The attack begins with apps that were previously available on Google Play that appear to be simple tools such as cleaners, games, or gallery utilities. When a user downloaded and opened one of these apps, it appeared to behave as advertised, giving no obvious signs of malicious activity.  

In the background, however, the app contacts a remote server, profiles the device, and downloads root exploits tailored to that device’s specific hardware and software. If the exploits succeed, the malware gains full control of the device. From that moment onward, every app that the user opens are injected with attacker‑controlled code.  

This allows the operators to access any app data and exfiltrate it to their servers. One of the targeted apps is WhatsApp. We recovered a payload designed to execute when WhatsApp launches, gather all necessary data to clone the session, and send it to the attacker’s infrastructure.   

On older, unsupported devices (Android 7 and lower) that no longer receive Android security updates as of September 2021, this rootkit is highly persistent; a standard factory reset will not remove it, and only reflashing the device with a clean firmware will fully restore the device.   

In total, we identified more than 50 of these malicious apps on Google Play, with at least 2.3 million downloads.  

McAfee identified the malicious apps, conducted the technical analysis, and reported its findings to Google through responsible disclosure channels. Following McAfee’s report, Google removed the identified apps from Google Play and banned the associated developer accounts. McAfee is a member of the App Defense Alliance, which supports collaboration across the mobile ecosystem to improve user protection. McAfee Mobile Security detects this malware as a High-Risk Threat.

Background And Key Findings

Android malware has been moving toward modular frameworks that update themselves remotely and adapt to each device. Campaigns like Triada and Keenadu have shown that replacing system libraries gives attackers persistence to survive factory resets. BADBOX has shown that backdoors pre-installed through the supply chain can reach millions of devices. Recent research has confirmed links between several of these families, suggesting shared tooling rather than isolated efforts. 

NoVoice fits both trends but does not rely on supply chain access. It reaches devices through Google Play and achieves the same level of persistence through exploitation. McAfee’s investigation revealed the following key findings: 

  • All carrier apps were distributed through Google Play. No sideloading required, no user interaction beyond opening the app. 
  • C2 infrastructure remains active at the time of publication. 
  • The C2 server profiles each device and delivers root exploits matched to its hardware and software version. 
  • The rootkit overwrites a core system library, causing every app on the device to run attacker code at launch. 
  • The infection survives factory reset and can only be removed by reflashing the firmware. 
  • The chain is fully plugin-based. Operators can push any payload to any app on the device at runtime. 
  • The only task we recovered clones WhatsApp sessions, but the framework is designed to accept any objective.

Naming  

The name comes from R.raw.novioce, a silent audio resource embedded in one of the later-stage payloads. It plays at zero volume to keep a foreground service alive, abusing Android’s media playback exemption. We believe it is a deliberate misspelling of “no voice.” 

Distribution Method 

All carrier apps were distributed through Google Play and request no unusual permissions. Their manifests include the same SDKs any legitimate app would (Firebase, Google Analytics, Facebook SDK, AndroidX). The malicious components are registered under tampered com.facebook.utils, blending in with the real Facebook SDK classes the apps already include.  

An example of one of the apps with hidden malware.
Figure 1One of the carrier apps on Google Play 

The initial payload is embedded in the app’s asset directory as a polyglot image. This means the file displays and renders a normal image, but a deeper inspection reveals that the encrypted malicious payload is appended after the PNG IEND marker. Since that marker signals to image viewers that the image data ends there, the appended payload remains hidden during normal viewing.

Geographical Prevalence 

The geographical prevalence map shows the highest infection rates in Nigeria, Ethiopia, Algeria, India, and Kenya, regions where budget devices and older Android versions that no longer receive security updates are common.

Malware Analysis

The following breakdown walks through each stage of the chain in order, from the moment a user opens the app to the moment stolen data leaves the device. No single file contains the full chain. Each stage decrypts and loads the next, most are delivered from the server at runtime. 

Figure 3. The NoVoice Rootkit Payloads
Figure 3. The NoVoice rootkit payloads

Stage 1: The Delivery

The moment the app opens, code injected into the legitimate Facebook SDK initialization path runs automatically. No user interaction is needed. It first checks whether the device has already been processed and, in most samples, whether it is running Android 12L or below. A subset of the carrier apps skips the version check entirely. If either check fails, it stops and logs a message disguised as a Facebook SDK error: “FacebookSdk: Failed in initStore.” 

If the device was already processed, the code cleans up files assumed to be left behind by previous runs, including paths that do not belong to any standard Android component. None of these are visible to the user. 

If the checks pass, the app reads a polyglot image from its own assets’ directory, extracts the encrypted payload (enc.apk) hidden after the image data, decrypts it to produce h.apk, and loads it into memory. It then deletes all intermediate files, temporary directories.

Figure 5: The malicious payload begins after the IEND marker, starting with the magic value CAFEBABE

Stage 2: The Gatekeeper 

The decrypted payload (h.apk) loads a native library (libkwc.so) that controls the rest of this stage. It first verifies it is running inside the intended carrier app by checking the package name and signing certificate against hardcoded values. It also checks whether the app is running in a debug environment. 

libkwc.so contains two encrypted embedded payloads. The first (sec.jar) is a gate designed to detect analysis environments. It runs 15 checks, including emulator detection, root indicators, debuggers, VPN and proxy connections, Xposed hooks, and GPS geofencing. If any check fails, the chain stops silently. The geofence compares the device’s location against bounding boxes for Beijing and Shenzhen hardcoded in the native library and excludes devices confirmed to be inside them. If the app does not have location permission, it cannot determine the device’s position and defaults to letting the chain continue. Two brands get special treatment: on Gionee devices, all checks except the geofence are skipped; on Meizu devices, the chain follows a separate code path entirely. Gionee devices have a documented history of shipping with pre-installed malware through supply chain compromise. 

Only if all checks in sec.jar pass does libkwc.so decrypt and load the second payload (hex.jar), which begins contacting the C2 server. If the gate fails, it deletes the working directory and stops. 

Figure 6: 15 validation checks before proceeding to the next stage
Figure 6: 15 validation checks before proceeding to the next stage

Stage 3: The Plugin 

Once the gate passes, hex.jar sets up a plugin framework built on an internal codebase the authors refer to as “kuwo” in their package names. It checks in with a C2 server every 60 seconds. Updates are delivered the same way as the initial payload: as image files with encrypted data hidden after the image content. The server returns download URLs in a response field named warningIcon, disguising plugin downloads as icon fetches. A log-deletion routine runs alongside the framework to remove forensic traces from the device. 

The first plugin delivered (rt) acts as an orchestrator. It manages sub-plugins and handles C2 communication. It checks in with the server, sending over 30 device identifiers including hardware model, kernel version, installed packages, and whether the device has already been rooted. The campaign’s name comes from this plugin: it embeds a silent audio resource named R.raw. novioce. 

The checkin tells the server two things: who this device is and whether it has already been rooted. If it has not, rt_plugin downloads security.jar, moving the chain into root exploitation.

Stage 4: The Exploit 

security.jar first checks whether the device is already rooted. If it has been, it stops. For unrooted devices, it sends the device’s chipset, kernel version, security patch date, and other identifiers to the C2. The server responds with a list of exploit binaries matched to that specific device. 

Before running any exploit, the rootkit installer (CsKaitno.d) is decrypted from an embedded resource and written to disk. The rootkit is already in place before any exploit runs. 

The exploits are downloaded one at a time from the C2’s CDN, each encrypted and verified before execution. We recovered 22 exploits in total. Our deep analysis of one revealed a three-stage kernel attack: an IPv6 use-after-free for kernel read, a Mali GPU driver vulnerability for kernel read/write, and finally credential patching and SELinux disablement. 

The expected end result is the same across all exploits: a root shell with SELinux disabled. From that shell, the exploit loads CsKaitno.d. This is where exploitation ends and persistence begins. 

Figure 8: SELinux enforcement disabled as part of the exploit chain.
Figure 8: SELinux enforcement disabled as part of the exploit chain

Stage 5: The Rootkit 

CsKaitno.d carries four encrypted payloads: library hooks for ARM32 and ARM64 (asbymol and bdlomsd), a bytecode patcher (jkpatch), and a persistence daemon (watch_dog). It first removes files associated with possible competing rootkits, then decrypts and writes its own payloads to disk. 

The installer backs up the original libandroid_runtime.so and replaces it with a hook binary matched to the device’s architecture. It also replaces libmedia_jni.so. The replacements are not copies of the original libraries. They are wrappers that intercept the system’s own functions. When any hooked function runs, it redirects to attacker code. 

Figure 9: Rootkit copying and preparing modified system libraries before remounting the filesystem as writable.
Figure 9: Rootkit copying and preparing modified system libraries before remounting the filesystem as writable

After replacing the libraries, jkpatch modifies pre-compiled framework bytecode on disk. This is a second layer of persistence: even if someone restores the original library, the framework’s own compiled code still contains the injected redirections

Stage 6: The Watchdog 

To survive reboots, the installer replaces the system crash handler with a rootkit launcher, installs recovery scripts, and stores a fallback copy of the exploitation stage on the system partition. If any component is removed, the rootkit can reinstall itself. 

It then deploys a watchdog daemon (watch_dog) that checks the installation every 60 seconds. If anything is missing, it reinstalls it. If that fails repeatedly, it forces a reboot, bringing the device back up with the rootkit intact. 

After cleaning up all staging files, the installer marks the device as compromised. On the next boot, the system’s process launcher (zygote) loads the replaced library, and every app it starts inherits the attacker’s code. 

Figure 10: Watchdog payload decrypted, written to disk, permissioned, and launched with a 60‑second restart interval.
Figure 10: Watchdog payload decrypted, written to disk, permissioned, and launched with a 60‑second restart interval

Stage 7: The Injection 

On the next boot, every app on the device loads the replaced system library. The injected code decides what to do based on which app it is running inside. Two payloads activate depending on the app. The malware authors named them BufferA and BufferB in their own code. Both are embedded as fragments inside the replaced libandroid_runtime.so from Stage 5, assembled in memory at runtime, and deleted from disk immediately after loading, leaving no files behind. BufferA runs inside the system’s package installer and can silently install or uninstall apps. BufferB runs inside any app with internet access. 

BufferB is the campaign’s primary post-exploitation tool. It operates two independent C2 channels with separate encryption keys and beacon intervals. Both channels send device fingerprints to the C2 and receive task instructions in return. 

If all primary domains fail and three or more days pass without contact, a fallback routine activates between 1 and 4 AM, reaching out to api[.]googlserves[.]com for a fresh domain list. Because BufferB runs inside any app with internet access, it can be active in dozens of apps simultaneously on a single device. 

Figure 11: Injection logic selecting BufferA for the package installer and BufferB for all other apps.
Figure 11: Injection logic selecting BufferA for the package installer and BufferB for all other apps

Stage 8: The Theft 

The only task payload we recovered is PtfLibc, delivered to BufferB from Alibaba Cloud OSS. Its target is WhatsApp. 

PtfLibc copies WhatsApp’s encryption database, extracts the device’s Signal protocol identity keys and registration ID, and pulls the most recent signed prekey. It also reads 12 keys from WhatsApp’s local storage, including the phone number, push name, country code, and Google Drive backup account. For the client keypair, it tries multiple decryption methods depending on how the device stores the key. 

It sends the stolen data to api[.]googlserves[.]com through multiple layers of encryption and deletes the temporary database copy when done. 

With these keys and session data, an attacker can clone the victim’s WhatsApp session onto another device.

Infrastructure 

The campaign spreads its C2 communication across multiple domains, each serving a different function. 

fcm[.]androidlogs[.]com handles initial device enrollment. Once the plugin framework activates, stat[.]upload-logs[.]com takes over as the primary C2 for plugin delivery, device checkin, exploit distribution, and result reporting. config[.]updatesdk[.]com serves as its fallback. Exploit binaries are hosted separately on download[.]androidlogs[.]com, with an S3-accelerated endpoint (logserves[.]s3-accelerate[.]amazonaws[.]com) as the primary CDN. This endpoint returned 403 errors during our analysis. 

Task payloads for BufferB are hosted on Alibaba Cloud OSS (prod-log-oss-01[.]oss-ap-southeast-1[.]aliyuncs[.]com). PtfLibc beacons to api[.]googlserves[.]com, a domain designed to look like Google service traffic at a glance. 

The domain separation is deliberate. Taking down one domain does not affect the others. The C2 can update BufferB’s domain lists at runtime, and a fallback routine fetches fresh domains from hardcoded backup endpoints if all configured domains go silent for three or more days. 

Recommendations 

Because the rootkit writes to the system partition, a factory reset does not remove it. A reset wipes user data but leaves system files intact. Compromised devices require a full firmware reflash to return to a clean state. Blocking the C2 domains and beacon patterns listed in this report at the network level can disrupt the chain at multiple stages. 

Attribution  

Several indicators link NoVoice to the Android.Triada family. The property (os.config.ppgl.status) NoVoice sets to mark a device as compromised is a known indicator of compromise for Android.Triada.231, a variant that uses the same property to track installation state. Both NoVoice and Triada.231 persist by replacing libandroid_runtime.so and hooking system functions so that every app runs attacker code at launch. Whether NoVoice is a direct evolution of Triada.231, a fork of its codebase, or a separate group reusing proven techniques, the shared approach suggests access to a common toolchain. 

Conclusion 

What makes NoVoice dangerous is not any single technique. It is the engineering effort behind the full chain: a self-healing pipeline that goes from a Play Store install to code execution inside every app on the device, survives factory reset, and monitors its own installation. The operators built a delivery system, an infrastructure. 

We recovered one task. The framework is designed to accept any number of them, for any app, at any time. The C2 infrastructure remains active. We do not know what other objectives have been deployed before, during, or after our analysis. The WhatsApp session theft we observed may be the least of it. 

The rootkit’s persistence model, overwriting a system library inherited by every process, patching pre-compiled framework bytecode, and monitoring its own installation with a watchdog, makes remediation difficult. 

This research underscores McAfee’s ongoing role in identifying advanced mobile threats and working with platform partners to protect users before largescale harm occurs.

Got a “Court Notice” Text? Ignore It. Plus, the Crunchyroll Breach: This Week in Scams

27 March 2026 at 11:00

A text that looks like it came straight from a courthouse is making the rounds across the U.S. And yes, I got it too. 

First things first, that’s a scam. And to be clear: DON’T SCAN THAT QR CODE. 

It’s the same playbook as last year’s toll road scams, just dressed up with a little more authority and a lot more pressure. 

Before doing anything, our team ran it through McAfee’s Scam Detector. It immediately flagged the message as suspicious, and that’s exactly the kind of moment this tool is built for. When something feels just real enough to second guess, it gives you a clear signal before you click, scan, or spiral. 

This shows how Scam Detector immediately flagged the text message and court image as suspicious.  
A screenshot showing Scam Detector in action.

How the scam works 

The text claims you’ve missed a payment, violated a law, or have some kind of outstanding “case.” It then pushes you to scan a QR code or click a link to resolve it quickly. 

From there, one of two things usually happens: 

  1. You’re taken to a fake payment page designed to steal your money, or 
  2. You’re prompted to download something that gives scammers access to your device or data  

Either way, the goal is the same: get you to act fast before you have time to question it. 

Here's the fake text our author received
Here’s the scam text I got in California. You’ll notice it looks exactly like the others across the country. 

The red flags in this message 

  • Urgent, threatening language about fines, penalties, or legal action  
  • Vague accusations with no real details about what you supposedly did  
  • Official-looking formatting like case numbers, clerk signatures, and judge names  
  • Copy-paste consistency across states: McAfee employees in New York and California received nearly identical messages with the same names  

There are reports of this scam popping up nationwide, but the rule is simple: law enforcement does not text you to demand payment or resolve legal issues. 

What to do if you scanned the QR code 

First, don’t panic. Then: 

  • Do not pay anything or enter personal information  
  • Do not delete apps you were told to install (this can make it harder to detect what happened)  
  • Run a device scan using a trusted security tool like McAfee’s free antivirus  
  • Keep an eye on your financial accounts and logins for unusual activity  

And that, my friends, is scam number one in this week’s This Week in Scams (new format, we’re experimenting a little).  

Let’s get into what else is on our radar. 

What to Know About an Alleged Crunchyroll Breach 

Anime streaming platform Crunchyroll is investigating claims of a data breach involving customer support ticket data, potentially impacting millions of users. 

According to TechCrunch, access appears to involve a third-party vendor system, a reminder that even strong security setups still rely on people and partners, which can introduce risk in everyday moments. 

Even if you’ve never entered your credit card into a support form, these tickets can still include: 

  • Email addresses  
  • Usernames  
  • Screenshots or account details  
  • Conversations that reveal habits, subscriptions, or personal context  

That’s more than enough for scammers to build highly believable follow-ups. 

Why this matters right now 

When breaches like this surface, scammers don’t wait. They use the moment to send emails and messages that feel timely, relevant, and legitimate. 

For example, scammers might send messages pretending to be Crunchyroll and suggesting you “click this link to secure your account” after the breach. In reality, that “security check” exposes your information.

This is where tools like Scam Detector come back into play, flagging suspicious links and messages even when they reference real companies or real events. 

What to do if you have a Crunchyroll account 

  • Change your password, especially if you’ve reused it elsewhere  
  • Turn on two-factor authentication  
  • Be cautious of emails referencing the breach or asking you to “secure your account”  
  • Avoid clicking links and go directly to the official site instead  

How McAfee Helps You Stay Ahead of Scams and Breaches

McAfee+ Advanced gives you multiple layers working together so you’re not left figuring it out in the moment: 

  • Scam Detector flags suspicious texts, emails, links, and even deepfake videos before you engage  
  • Safe Browsing helps block risky sites if you do click or scan  
  • Device Security helps detect and remove malicious apps or downloads  
  • Identity Monitoring alerts you if your personal info shows up where it shouldn’t, so you can act fast  
  • Personal Data Cleanup helps remove your information from data broker sites, making you a harder target in the first place  
  • Secure VPN keeps your data private, especially on public Wi-Fi  

Plus our instant QR code scam checks will flag suspicious QR codes before you scan them.

QR Scan Example

Safety tips to carry into next week 

  • Slow down when a message creates urgency. That’s the hook  
  • Don’t scan QR codes or click links from unexpected texts  
  • Go directly to official websites instead of using links sent to you  
  • Use tools that flag scams in real time so you don’t have to guess  

The reality is, these scams are designed to look normal. You shouldn’t have to be an expert to spot them. That’s why McAfee’s here to help. 

We’ll be back next week with more scams making headlines.

This Week in Scams: Why That “Booking Confirmation” Message Might Be Fake

20 March 2026 at 16:46

Today marks the start of Spring in the Northern Hemisphere, and with warmer weather setting in summer trips are vacation planning are starting to take shape.   

But before you respond to that message about your hotel booking or payment confirmation, it’s worth asking: is it actually legit? 

This week in scams, we’re breaking down a travel phishing scheme making the rounds through realistic booking messages, as well as new McAfee research on betting scams and AI-driven malware. 

We’ll walk through what happened, what to watch for, and how McAfee’s tools can help you stay safe. 

Scammers Who Know Your Exact Travel Reservation Details 

A new phishing campaign targeting travelers is exploiting hotel booking platforms like Booking.com, and it’s convincing enough to fool even cautious users. 

According to reporting from ITBrew and Cybernews, attackers are running a multi-stage scam: 

How The Booking Scam Works 

Scam Stage  How It Works  What You’ll Notice  How to Protect Yourself  Where McAfee Helps 
Stage 1: Hotel account gets compromised  Attackers phish or hack hotel staff to access booking platforms and guest reservation data.  You won’t see this part — it happens behind the scenes.  Use strong, unique passwords and enable multi-factor authentication on your own accounts to reduce risk of similar breaches.  Identity Monitoring can alert you if your personal information appears in suspicious places or data leaks. 
Stage 2: You receive a realistic message  Scammers use stolen booking data to send messages via WhatsApp, email, or even booking platforms.  The message includes your real name, hotel, and travel dates, making it feel legitimate.  Be cautious of unexpected outreach, even if the details are correct. Don’t assume accuracy means authenticity.  Scam detection tools can help flag suspicious messages and identify potential phishing attempts. 
Stage 3: Urgency is introduced  The message claims there’s an issue with your reservation and pushes you to act quickly.  Phrases like “confirm within 12 hours” or “risk cancellation” create pressure.  Pause before acting. Legitimate companies rarely require urgent payment changes without prior notice.  Scam detection can help identify high-risk messages designed to pressure you into quick decisions. 
Stage 4: You’re sent to a fake payment page  A link leads to a convincing lookalike site designed to steal your payment details.  The page looks real but may have subtle URL differences or unusual formatting.  Always navigate directly to the official website or app instead of clicking links in messages.  Safe Browsing tools can help block risky or known malicious websites before you enter sensitive information. 

March Madness Brackets, Bets, and Bad Actors 

March Madness brings brackets, bets, and a flood of bad actors. 

New McAfee research found that 1 in 3 Americans (32%) say they’ve experienced a betting or gambling scam, and nearly a quarter (24%) say they’ve lost money to one. On average, victims reported losing $547. 

That’s not surprising when you look at the environment around the tournament. More than half of Americans are watching, more than half are participating in some form of betting, and 82% say they’ve seen betting promotions in the past year. 

Some of the most common setups this season include: 

  • “Guaranteed win” or “can’t lose” betting tips that require payment upfront 
  • Fake sportsbook promotions offering bonus bets or free credits 
  • Messages claiming you have winnings, but need to pay a fee to unlock them 
  • Impersonation scams posing as sportsbook support or betting platforms 
  • Invitations to private “VIP betting groups” on WhatsApp or Telegram 

The takeaway:
If a betting offer promises guaranteed results, demands the use of bizarre apps and sites, asks for money upfront, or pushes you to act quickly, it’s not an edge. It’s a scam. 

“AI-Written” Malware Is Hiding in Everyday Downloads 

Not all scams start with a message. Some start with a search. 

McAfee Labs uncovered a large-scale malware campaign hiding inside hundreds of fake downloads, including game mods, AI tools, drivers, and trading utilities. 

In January alone, researchers identified: 

  • 443 malicious ZIP files disguised as legitimate software 
  • 1,700+ file names used to make those downloads look credible 
  • 48 variants of a malicious DLL file used to infect devices 

These weren’t hosted on obscure corners of the internet either. The files were distributed through platforms people recognize, including Discord, SourceForge, and file-sharing sites. 

Here’s how the attack typically works: 

  • You search for a tool. 
  • You download what looks like the right file. 
  • It opens normally at first. 

Then, behind the scenes, malware loads quietly and begins pulling in additional code. In some cases, victims are shown fake error messages while the real infection happens in the background. 

From there, attackers can: 

  • Turn your device into a cryptocurrency mining machine 
  • Install additional malware like infostealers or remote access tools 
  • Slow down your system while running hidden processes 

What makes this campaign stand out is that some of the code appears to have been generated with help from AI tools. 

That doesn’t mean AI is running the attack on its own. But it does suggest attackers are using AI to: 

  • Generate code faster 
  • Create more variations of malware 
  • Scale campaigns more efficiently 

In other words, the barrier to building malware is getting lower. 

The takeaway:
If a download is unofficial, hard to find, or feels like a shortcut, it’s worth slowing down. The file may look right, but that doesn’t mean it’s safe. 

How McAfee+ Advanced Works in These Scam Moments 

Whether it’s a message about your booking, a betting offer that looks legitimate, or a download that appears to be exactly what you were searching for, these scams all rely on the same thing: they blend into everyday moments. 

That’s where having backup like McAfee+ Advanced comes in. It includes: 

  • McAfee’s Scam Detector, which helps flag suspicious links in texts and messages like the ones used in these booking and betting scams, so you can spot something risky before you engage
  • Web protection and real-time device security, helping protect against risky links, malicious sites, and evolving threats if you do click, including fake betting platforms or malware hidden in downloads
  • Personal Data Cleanup, which helps remove your information from sites that sell it, making it harder for scammers to access the personal details that make messages and scams feel legitimate
  • Secure VPN, which helps keep your personal info safe and private anywhere you use public Wi-Fi, like hotels, airports, and cafés while traveling
  • Identity Monitoring and alerts, with 24/7 scans of the dark web to help ensure your personal and financial information isn’t being exposed or reused
  • Credit and transaction monitoring, so you can get alerts about suspicious financial activity if your information is ever compromised 
  • Identity restoration support and up to $2 million in identity theft coverage, giving you access to US-based experts and added peace of mind if something does go wrong 

Stay skeptical, verify before you click, and we’ll see you next week with more.

New Research: Hackers Are Using AI-Written Code to Spread Malware

18 March 2026 at 21:48

McAfee Labs has uncovered a widespread malware campaign hiding inside fake downloads for things like game mods, AI tools, drivers, and trading utilities. 

In January 2026, researchers observed 443 malicious ZIP files impersonating software people might actively search for online. Across those files, McAfee identified 48 malicious WinUpdateHelper.dll variants used to infect devices. The campaign was spread through a mix of file-hosting and content delivery services, including Discord, SourceForge, FOSSHub, and mydofiles[.]com. 

What makes this campaign especially notable is that some parts of it appear to have been built with help from large language models (LLMs). McAfee researchers found signs that certain scripts likely used AI-generated code, which may have helped the attackers create and scale the campaign faster. 

That does not mean AI created the whole operation on its own. But it does suggest AI may be helping cybercriminals lower the effort needed to build malware and launch attacks. 

Want the full research? Dive in here. 

We break down the top takeaways below. 

What McAfee Found 

Finding  What it means 
443 malicious ZIP files  Attackers created many different fake downloads to reach more victims 
48 malicious DLL variants  The campaign used multiple versions of the malware, not just one file 
1,700+ file names observed  The same threat was repackaged under many different names to look convincing 
17 distinct kill chains  Researchers found multiple attack flows, but they followed a similar overall pattern 
Hosted on familiar platforms  The malware was distributed through services users may recognize, including Discord and SourceForge 
AI-assisted code suspected  Some scripts contained explanatory comments and patterns that strongly suggest LLM assistance 
Cryptomining and additional malware observed  Infected devices could be used to mine cryptocurrency or receive more malicious payloads 

What Is “AI-Written Malware”? 

In this case, “AI-written malware” does not mean an AI system independently invented and launched the attack. 

Instead, McAfee Labs found evidence that the attackers very likely used AI tools to help generate some of the code used in the campaign, especially in certain PowerShell scripts. 

Put simply: 

Term  Plain-English meaning 
Large language model (LLM)  An AI system that can generate text and code based on prompts 
AI-assisted malware  Malware where attackers appear to have used AI tools to help write or structure parts of the code 
Vibe coding  A style of coding where someone describes what they want and an AI does much of the writing 

This matters because it can make malware development faster, easier, and more scalable for attackers.

How The Fake Download Attack Works 

The attack begins when someone searches for software online and downloads what looks like the tool they wanted. 

That tool might appear to be a game mod, AI voice changer, emulator, trading utility, VPN, or driver. But behind the scenes, the ZIP archive includes malicious components that start the infection. 

Step  What happens 
1. A user downloads a fake file  The ZIP archive is disguised as something useful or desirable, such as a mod menu, AI tool, or driver 
2. The file appears normal at first  In some cases, the package includes a legitimate executable so it feels more convincing 
3. A malicious DLL is loaded  A hidden malicious file, often WinUpdateHelper.dll, starts the real attack 
4. The user is distracted  The malware may display a fake “missing dependency” message and redirect the user to install unrelated software 
5. A PowerShell script is pulled from a remote server  While the user is distracted, the malware contacts a command-and-control server and runs additional code 
6. More malware is installed  Depending on the sample, the device may receive coin miners, infostealers, or remote access tools 
7. The infected device is abused for profit  In many cases, attackers use the victim’s system resources to mine cryptocurrency in the background 

What Kinds of Files Were Used as Bait 

McAfee found that the attackers cast a very wide net. The malicious ZIP files impersonated many types of software, including: 

Bait category  Examples 
Gaming tools  game mods, cheats, executors, Roblox-related tools 
AI-themed tools  AI image generators, AI voice changers, AI-branded downloads 
System utilities  graphics drivers, USB drivers, emulators, VPNs 
Trading or finance tools  stock-market utilities and related downloads 
Fake security or malware tools  fake stealers, decryptors, and other risky-looking utilities 

That broad range is part of what made the campaign effective. It was designed to catch people already looking for shortcuts, unofficial tools, or hard-to-find software. 

Why McAfee Researchers Believe AI Was Used 

One of the strongest clues came from the comments inside some of the attack scripts. 

McAfee researchers found explanatory comments that looked more like AI-generated instructions than the kind of shorthand attackers usually leave for themselves. In one example, a comment referred to downloading a file from “your GitHub URL,” which suggests the code may have come from a generated template and was not fully cleaned up before use. 

These details do not prove every part of the campaign was AI-made. But they do support McAfee’s assessment that certain components were likely generated with help from large language models. 

What Happens on an Infected Device 

In many cases, the malware was used to turn victims’ computers into quiet crypto-mining machines. 

McAfee observed mining activity involving several cryptocurrencies, including: 

  • Ravencoin 
  • Zephyr 
  • Monero 
  • Bitcoin Gold 
  • Ergo 
  • Clore 

Some samples also downloaded additional payloads such as SalatStealer or Mesh Agent. 

For victims, that can mean: 

Possible effect  What it may look like 
Slower performance  apps lag, games stutter, system feels unusually sluggish 
High CPU or GPU usage  fans run constantly, laptop gets hot, battery drains faster 
Background malware activity  unknown processes, suspicious downloads, unexpected behavior 
Potential data theft  if an infostealer or remote access tool is installed 

McAfee was also able to trace several Bitcoin wallets tied to the campaign. At the time of the report, those wallets held about $4,536 in Bitcoin, while total funds received were approximately $11,497.70. Researchers note the real total could be higher because some of the currencies involved are harder to trace. 

Who Was Targeted Most 

This campaign was observed most heavily in: 

  • United States 
  • United Kingdom 
  • India 
  • Brazil 
  • France 
  • Canada 
  • Australia 

That does not mean users elsewhere were unaffected. These were simply the countries where researchers saw the highest prevalence.

  Red Flags To Watch For 

Even though the campaign used advanced techniques, the warning signs for users were often familiar. 

Red flag  Why it matters 
You found the file through a random link  Unofficial forums, Discord links, and file-hosting pages are common malware delivery paths 
The download is a ZIP for something sketchy or unofficial  Cheats, cracks, mod tools, and unofficial utilities carry higher risk 
You get a “missing dependency” message  Attackers may use this to push a second download while the real infection happens in the background 
The file name looks right, but the source feels wrong  Familiar names can be faked easily 
Your PC suddenly slows down or overheats  Hidden cryptominers often abuse system resources 
You notice new, unrelated software installed  The campaign sometimes used unwanted software installs as a distraction 

How To Stay Safe From Malware Hidden in Fake Downloads 

This campaign is a reminder that not every convincing file is a safe one. A few habits can reduce your risk significantly. 

Safety step  Why it helps 
Download software only from official sources  This lowers the chance of accidentally installing a trojanized file 
Avoid cheats, cracks, and unofficial mods  These categories are common bait for malware campaigns 
Be skeptical of dependency prompts  Unexpected requests to install helper files or missing components can be part of the attack 
Keep your security software updated  Current protection can help detect known threats and suspicious behavior 
Pay attention to system performance  A suddenly hot, loud, or slow PC may be a sign something is running in the background 
Review what you download before opening it  Even a familiar file name does not guarantee a file is legitimate 

McAfee helps protect against malware threats like these with multiple layers of security, including malware detection and safer browsing protections designed to help stop risky downloads before they can do damage. 

What To Do If You Think You Opened One of These Files 

If you think you downloaded and ran a suspicious file like one described in this campaign: 

Action  Why it matters 
Disconnect from the internet  This can help interrupt communication with attacker-controlled servers 
Run a full security scan  A trusted scan can help identify malicious files and behavior 
Delete suspicious downloads  Remove the file and avoid reopening it 
Check for unfamiliar software or startup items  The infection may have installed additional components 
Change important passwords from a clean device  This is especially important if data-stealing malware may have been involved 
Monitor accounts for unusual activity  Keep an eye on email, banking, and other sensitive accounts 

If your computer continues acting strangely after a scan, it may be worth getting professional help. 

What This Means for the Future of Malware 

This campaign highlights how cybercrime is evolving. 

The core risk is not just fake downloads. It is the fact that attackers are using AI tools to help generate code, create variations, and speed up parts of the malware development process. 

That can make campaigns like this easier to scale and harder to ignore. 

For everyday users, the takeaway is simple: if a file seems unofficial, rushed, or too good to be true, pause before opening it. A fake download may look like a shortcut, but it can quietly turn your device into a target.

1 in 3 Has Experienced a Betting Scam. What March Madness Fans Should Know

17 March 2026 at 12:55

Whether you’re a hardcore basketball fan or the office colleague who gets roped into filling out a bracket every year, March Madness is the season for brackets, office pools, and last-minute picks. 

More than half of Americans (57%) plan to watch the NCAA basketball tournament, and 55% say they participate in some kind of betting or bracket activity during March Madness, from office pools to licensed sportsbook wagers.  

But where there’s excitement and money, scammers aren’t far behind. 

New research from McAfee finds that 1 in 3 Americans (32%) say they’ve experienced a betting or gambling scam, and 24% say they’ve lost money to one, with victims losing an average of $547. 

Big events like March Madness create the perfect storm: massive attention, constant betting promotions, and fans searching online for predictions, tips, and an edge. 

Scammers know it, and they’re exploiting the moment. 

This example shows an incredible realistic, but fake, Fanduel site created by scammers to impersonate the real thing.
This example shows an incredibly realistic, but fake, FanDuel site created by scammers to impersonate the real thing.

Why March Madness is Prime Time for Betting Scams 

Sports betting promotions are everywhere during major events like March Madness. 

According to McAfee research, 82% of Americans say they’ve seen sports betting promotions or offers in the past year, often on social media, streaming broadcasts, and sports websites. 

That flood of promotions makes it easier for scams to blend in with legitimate content. 

Many scams start the same way legitimate offers do, through messages, ads, or links promising bonuses or tips. But once someone clicks or responds, the situation can escalate quickly. 

For example: 

  • 42% of Americans say they’ve been asked to click a link sent via email tied to a betting offer 
  • Others report links sent through social media messages or text messages directing them to betting sites, apps, or private betting groups 

In many cases, victims are then asked to send money to unlock winnings, activate accounts, or access premium betting picks. 

The payout rarely exists. 

The Most Common Betting Scams Fans Encounter 

Betting scams come in several forms, but many follow familiar patterns. 

Here are some of the most common tactics reported in McAfee’s research: 

Scam Type  Definition  How It Works  Red Flags 
Guaranteed Win Scam  A betting scam where someone promises a “guaranteed win,” “sure bet,” or “can’t lose” outcome in exchange for money, clicks, or sign-ups. According to McAfee Findings, about 1 in 6 Americans say they’ve received these kinds of messages, which are designed to lure fans looking for an edge.  Scammers send private messages, emails, or social posts claiming they have insider knowledge or a lock on a game. The goal is usually to get the victim to pay for picks, join a private group, or click a malicious link.  Claims that a bet is guaranteed, pressure to act fast, requests for payment to access picks, and promises that sound risk-free. 
Fake Free Bet Promotion Scam  A scam that pretends to offer bonus bets, deposit matches, or free credits through a fake sportsbook promotion.  The victim sees what looks like a real sportsbook offer, often through social media, email, or text. Clicking may lead to a fake site that steals login details, payment information, or deposits.  Unfamiliar brand names, unofficial links, urgent sign-up language, and promotions that seem unusually generous. 
Winnings Release Fee Scam  A scam where a victim is told they have winnings waiting, but must first pay a fee, deposit, or processing charge to collect them.  The scammer claims the user has won money, then invents a reason payment is required before the funds can be released. Once the fee is sent, the payout never arrives.  Requests to pay before receiving winnings, vague “processing” or “verification” fees, and pressure to send money immediately. 
Fake Betting App or Website Scam  A scam involving a fraudulent app or website designed to look like a real sportsbook or betting platform.  Victims are directed to a fake platform where they may create an account, enter personal information, or deposit money. The site may appear legitimate, but withdrawals are blocked or impossible.  Slightly misspelled URLs, strange app download paths, poor website quality, and platforms that make deposits easy but withdrawals difficult. 
Sportsbook Impersonation Scam  A scam in which someone pretends to represent a legitimate betting platform or sportsbook support team.  The scammer contacts the victim claiming there is an issue with an account, a bonus, or winnings. They then ask for login credentials, payment details, or personal information.  Requests for passwords, bank details, or identity information; unexpected outreach; and messages pushing you to resolve an “account issue” through a link. 
Fake Insider Tip Scam  A scam that uses claims of insider information, fixed games, or special access to make a betting offer sound exclusive and trustworthy.  Scammers position themselves as experts, insiders, or connected sources who can help the victim beat the odds. The real goal is usually payment, account access, or enrollment in a scam betting channel.  Claims of fixed outcomes, “insider” knowledge, exclusive access, and offers that rely on secrecy or urgency. 
Celebrity or Influencer Endorsement Scam  A betting scam that uses fake or misleading celebrity, athlete, or influencer endorsements to make an offer seem legitimate.  Scammers create ads, videos, or posts that appear to feature a public figure recommending a betting platform, app, or tip service. In some cases, AI-generated content makes these endorsements look more convincing.  Endorsements that seem off-brand, videos or graphics that look unnatural, unfamiliar accounts, and promotions tied to fake urgency or suspicious links. 
Private Betting Group Scam  A scam that tries to move betting conversations into private channels like WhatsApp, Telegram, or Signal.  After initial contact on social media or another public platform, the scammer encourages the victim to join a private group for “exclusive picks,” “VIP bets,” or “premium insights.” These groups are often used to pressure victims into sending money or clicking malicious links.  Pressure to move off-platform quickly, promises of VIP access, requests for payment to join, and little proof that the group is legitimate. 

Who Is Most Likely to Encounter Betting Scams 

McAfee’s research found that Americans under 45 are significantly more likely to encounter betting scams, with 44% saying they’ve experienced one compared with 19% of those over 45. 

Men also report higher exposure, with 40% saying they’ve experienced a betting scam, compared with 25% of women.  

Men and younger adults are also more likely to participate in brackets, fantasy sports, or sportsbook betting, the same spaces where scams often appear.

AI Is Making Betting Scams Harder to Spot 

Artificial intelligence is beginning to change how scams look and sound. 

About 1 in 5 Americans say they’ve encountered betting scams that appeared more realistic because of AI, and 27% believe they’ve seen AI-generated betting content such as fake promotions, images, or videos.  

Among those who encountered AI-driven scams: 

  • 58% reported AI-generated images or graphics in betting ads 
  • 57% saw AI-written messages that sounded natural or personalized 
  • 45% encountered fake celebrity or influencer endorsements 
  • 36% interacted with chatbots posing as betting experts or support agents  

As these tools improve, scam messages are becoming smoother, more convincing, and harder to distinguish from legitimate promotions. 

Safety Check  What To Do 
Be skeptical of “guaranteed wins”  No bet is risk-free. Ignore messages promising sure bets, insider picks, or guaranteed outcomes. 
Use only licensed sportsbooks  Stick to official betting apps and well-known sportsbooks. Avoid unfamiliar websites or apps. 
Don’t click betting links from unknown messages  If you receive a betting offer via email, text, or social media, go directly to the official site instead of clicking the link. 
Never pay fees to unlock winnings  If someone says you must send money to claim winnings or activate a betting account, it’s almost certainly a scam. 
Be cautious of private betting groups  Invitations to “VIP betting groups” on apps like Telegram or WhatsApp are often used to promote scam picks or collect payments. 
Protect your accounts  Use strong passwords and turn on two-factor authentication wherever possible. Try our free strong password generator. 
Use scam detection tools  Tools like McAfee’s Scam Detector can flag suspicious links, websites, and messages before you engage. 

March Madness is meant to be fun, filling out brackets, debating picks with friends, and cheering for the next big upset. Betting can be part of that excitement, but it’s worth remembering that scammers are watching the tournament too. 

A simple rule of thumb can go a long way: if a betting offer promises guaranteed wins, asks for money upfront, or pushes you to act quickly, take a step back and verify it first.  

The safest plays are the ones where you slow down, stick to trusted platforms, and keep your personal information protected.
