So I cooked up a fake transaction for shits and giggles. No valid IBAN. No real user. No device. No signature. No token. No nothing. Just pure distilled bullshit in a JSON payload.
Guess what? “Transaction accepted” “attack_success”: true “fraud_score”: 0.99999 System looked at it and said: “yeah, looks good to me.”
I even told the sandbox I was sending 10k EUR from FAKE_IBAN_901 to INVALID_IBAN_123 using a spoofed IMEI and some RSA nonsense I made up in Notepad. Bunq backend? Nodded politely and gave me a sandbox TXID.
It gets better — it accepts critical priority flags, fake biometric hashes, invalid currency codes, all wrapped in a nice little “success” bow.
This ain’t a bug, this is a fuckin’ confessional.
If bunq staff lurking here: hit me up. This ain’t a ransom, but y’all might wanna know just how open wide your API goes when someone whispers sweet nothings like tpp_id: "lol_fake_999".
We got logs. We got timestamps. We got receipts.
Your move, bunq.

A Template Injection vulnerability in the latest version of Kong’s Insomnia API Client (v.11.2.0) leads to Remote Code Execution.
As we continue to evolve the field of AI, a new branch that has been accelerating recently is Agentic AI. Multiple definitions are circulating, but essentially, Agentic AI involves one or more AI systems working together to accomplish a task using tools in an unsupervised fashion. A basic example of this is tasking an AI Agent with finding entertainment events I could attend during summer and emailing the options to my family.
Agentic AI requires a few building blocks, and while there are many variants and technical opinions on how to build, the basic implementation typically includes a Reasoning LLM (Large Language Model) – like the ones behind ChatGPT, Claude, or Gemini – that can invoke tools, such as an application or function to perform a task and return results. A tool can be as simple as a function that returns the weather, or as complex as a browser commanding tool that can navigate through websites.
While this technology has a lot of potential to augment human productivity, it also comes with a set of challenges, many of which haven’t been fully considered by the technologists working on such systems. In the cybersecurity industry, one of the core principles we all live by is implementing “security by design”, instead of security being an afterthought. It is under this principle that we explore the security implications (and threats) around Agentic AI, with the goal of bringing awareness to both consumers and creators:
With the proliferation of Agentic AI, we will see both opportunities to make our life better as well as new threats from bad actors exploiting the same technology for their gain, by either intercepting and poisoning legitimate users AI Agents, or using Agentic AI to perpetuate attacks. With this in mind, it’s more important than ever to remain vigilant, exercise caution and leverage comprehensive cybersecurity solutions to live safely in our digital world.

New online threats emerge every day, putting our personal information, money and devices at risk. In its 2024 Internet Crime Report, the Federal Bureau of Investigation reports that 859,532 complaints of suspected internet crime—including ransomware, viruses and malware, data breaches, denials of service, and other forms of cyberattack—resulted in losses of over $16 billion—a 33% increase from 2023.
That’s why it is essential to stay ahead of these threats. One way to combat these is by conducting virus scans using proven software tools that constantly monitor and check your devices while safeguarding your sensitive information. In this article, we’ll go through everything you need to know to run a scan effectively to keep your computers, phones and tablets in tip-top shape.
Whether you think you might have a virus on your computer or devices or just want to keep them running smoothly, it’s easy to do a virus scan.
Each antivirus program works a little differently, but in general the software will look for known malware with specific characteristics, as well as their variants that have a similar code base. Some antivirus software even checks for suspicious behavior. If the software comes across a dangerous program or piece of code, the antivirus software removes it. In some cases, a dangerous program can be replaced with a clean one from the manufacturer.
Before doing a virus scan, it is useful to know the telltale signs of viral presence in your device. Is your device acting sluggish or having a hard time booting up? Have you noticed missing files or a lack of storage space? Have you noticed emails or messages sent from your account that you did not write? Perhaps you’ve noticed changes to your browser homepage or settings? Maybe you’re seeing unexpected pop-up windows, or experiencing crashes and other program errors. These are just some signs that your device may have a virus, but don’t get too worried yet because many of these issues can be resolved with a virus scan.
Free virus scanner tools, both in web-based and downloadable formats, offer a convenient way to perform a one-time check for malware. They are most useful when you need a second opinion or are asking yourself, “do I have a virus?” after noticing something suspect.
However, it’s critical to be cautious. For one, cybercriminals often create fake “free” virus checker tools that are actually malware in disguise. If you opt for free scanning tools, it is best to lean on highly reputable cybersecurity brands. On your app store or browser, navigate to a proven online scanning tool with good reviews or a website whose URL starts with “https” to confirm you are in a secure location.
Secondly, free tools are frequently quite basic and perform only the minimum required service. If you choose to go this path, look for free trial versions that offer access to the full suite of premium features, including real-time protection, a firewall, and a VPN. This will give you a glimpse of a solution’s comprehensive, multi-layered security capability before you commit to a subscription.
If safeguarding all your computers and mobile devices individually sounds overwhelming, you can opt for comprehensive security products that protect computers, smartphones and tablets from a central, cloud-based hub, making virus prevention a breeze. Many of these modern antivirus solutions are powered by both local and cloud-based technologies to reduce the strain on your computer’s resources.
This guide will walk you through the simple steps to safely scan your computer using reliable online tools, helping you detect potential threats, and protect your personal data.
When selecting the right antivirus software, look beyond a basic virus scan and consider these key features:
The process of checking for viruses depends on the device type and its operating system. Generally, however, the virus scanner will display a “Scan” button to start the process of checking your system’s files and apps.
Here are more specific tips to help you scan your computers, phones and tablets:
If you use Windows 11, go into “Settings” and drill down to the “Privacy & Security > Windows Security > Virus & Threat Protection” tab, which will indicate if there are actions needed. This hands-off function is Microsoft’s own basic antivirus solution called Windows Defender. Built directly into the operating system and enabled by default, this solution provides a baseline of protection at no extra cost for casual Windows users. However, Microsoft is the first to admit that it lags behind specialized paid products in detecting the very latest zero-day threats.
Mac computers don’t have a built-in antivirus program, so you will have to download security software to do a virus scan. As mentioned, free antivirus applications are available online, but we recommend investing in trusted software that is proven to protect you from cyberthreats.
If you decide to invest in more robust antivirus software, running a scan is usually straightforward and intuitive. For more detailed instructions, we suggest searching the software’s help menu or going online and following their step-by-step instructions.
Smartphones and tablets are powerful devices that you likely use for nearly every online operation in your daily life from banking, emailing, messaging, connecting, and storing personal information. This opens your mobile device to getting infected through malicious apps, especially those downloaded from unofficial stores, phishing links sent via text or email, or by connecting to compromised wi-fi networks.
Regular virus scans with a mobile security software are crucial for protecting your devices. Be aware, however, that Android and IOS operating systems merit distinct solutions.
Antivirus products for Android devices abound due to this system’s open-source foundation. However, due to Apple’s strong security model, which includes app sandboxing, traditional viruses are rare on iPhones and iPads. However, these devices are not immune to all threats. You can still fall victim to phishing scams, insecure Wi-Fi networks, and malicious configuration profiles. Signs of a compromise can include unusual calendar events, frequent browser redirects, or unexpected pop-ups.
Apple devices, however, closed platform doesn’t easily accommodate third-party applications, especially unvetted ones. You will most likely find robust and verified antivirus scanning tools on Apple’s official app store.
Before you open any downloaded file or email attachment, it’s wise to check it for threats. To perform a targeted virus scan on a single file, simply right-click the file in Windows Explorer or macOS Finder and select the “Scan” option from the context menu to run the integrated virus checker on a suspicious item.
For an added layer of security, especially involving files from unknown sources, you can use a web-based file-checking service that scans for malware. These websites let you upload a file, which is then analyzed by multiple antivirus engines. Many security-conscious email clients also automatically scan incoming attachments, but a manual scan provides crucial, final-line defense before execution.
Once the scan is complete, the tool will display a report of any threats it found, including the name of the malware and the location of the infected file. If your antivirus software alerts you to a threat, don’t panic—it means the program is doing its job.
The first and most critical step is to follow the software’s instructions. It might direct you to quarantine the malicious file to isolate the file in a secure vault where it can no longer cause harm. You can then review the details of the threat provided by your virus scanner and choose to delete the file permanently, which is usually the safest option.
After the threat is handled, ensure your antivirus software and operating system are fully updated. Finally, run a new, full system virus scan to confirm that all traces of the infection have been eliminated. Regularly backing up your important data to an external drive or cloud service can also be a lifesaver in the event of a serious infection.
The most effective way to maintain your device’s security is to automate your defenses. A quality antivirus suite allows you to easily schedule a regular virus scan so you’re always protected without having to do it manually. A daily quick scan is a great habit for any user; it’s fast and checks the most vulnerable parts of your system. Most antivirus products regularly scan your computer or device in the background, so a manual scan is only needed if you notice something dubious, like crashes or excessive pop-ups. You can also set regular scans on your schedule, but a weekly full scan is ideal.
These days, it is essential to stay ahead of the wide variety of continuously evolving cyberthreats. Your first line of defense against these threats is to regularly conduct a virus scan. You can choose among the many free yet limited-time products or comprehensive, cloud-based solutions.
While many free versions legitimately perform their intended function, it’s critical to be cautious as these are more often baseline solutions while some are malware in disguise. They also lack the continuous, real-time protection necessary to block threats proactively.
A better option is to invest in verified, trustworthy, and all-in-one antivirus products like McAfee+ that, aside from its accurate virus scanning tool, also offers a firewall, a virtual private network, and identity protection. For complete peace of mind, upgrading to a paid solution like McAfee Total Protection is essential for proactively safeguarding your devices and data in real-time, 24/7.

We use our smartphones for everything under the sun, from work-related communication to online shopping, banking transactions, and social media. For this reason, our phones store a lot of personal data, including contacts, account details, and bank account logins.
High online usage also makes your devices vulnerable to viruses, a type of malware that replicate themselves and spread throughout the entire system. They can affect your phone’s performance or, worse, compromise your sensitive information so that hackers can benefit monetarily.
In this article, we will give you a rundown of viruses that can infect your phone and how you can identify and eliminate them. We will also provide some tips for protecting your phone from viruses in the first place.
iPhones and Android devices run on different operating systems, hence differences in how they resist viruses and how these affect each system.
While iOS hacks can still happen, Apple’s operating system is reputed to be highly resistant from viruses because of its design. By restricting interactions between apps, Apple’s operating system limits the movement of a virus across the device. However, if you jailbreak your iPhone or iPad to unlock other capabilities or install third-party apps, then the security restrictions set by Apple’s OS won’t work. This exposes your iPhone and you to vulnerabilities that cybercriminals can exploit.
Android phones, while also designed with cybersecurity in mind, rely on open-source code, making them an easier target for hackers. Additionally, giving users the capability to install third-party apps from alternative app stores such as the Amazon or Samsung Galaxy app stores makes Android devices open to viruses.
Cybercriminals today are sophisticated and can launch a variety of cyberattacks on your smartphone. Some viruses that can infect your phone include:
Ultimately, contracting a virus on your phone or computer comes down to your browsing and downloading habits. These are the most common ways it could happen:
Now that you know how your phone could be infected by a virus, look out for these seven signs that occur when malicious software is present:
Most pop-up ads don’t carry viruses but are only used as marketing tools. However, if you find yourself closing pop-up ads more often than usual, it might indicate a virus on your phone. These ads might be coming from apps in your library that you didn’t install. In this case, uninstall them immediately as they tend to carry malware that’s activated when the app is opened or used.
When you accidentally download apps that contain malware, your device has to work harder to continue functioning. Since your phone isn’t built to support malware, there is a good chance it will overheat.
If your contacts receive unsolicited scam emails or messages on social media from your account, especially those containing suspicious links, a virus may have accessed your contact list. It’s best to let all the recipients know that your phone has been hacked so that they don’t download any malware themselves or forward those links to anybody else.
An unusually slow-performing device is a hint of suspicious activity on your phone. The device may be slowing down because it is working harder to support the downloaded virus. Alternatively, unfamiliar apps might be taking up storage space and running background tasks, causing your phone to run slower.
Are you finding credit card transactions in your banking statements that you don’t recognize? It could be an unfamiliar app or malware making purchases through your account without your knowledge.
A sudden rise in your data usage or phone bill can be suspicious. A virus might be running background processes or using your internet connection to transfer data out of your device for malicious purposes.
An unusually quick battery drain may also cause concern. Your phone will be trying to meet the energy requirements of the virus, so this problem is likely to persist for as long as the virus is on the device.
You may have an inkling that a virus resides in your phone, but the only way to be sure is to check. An easy way to do this is by downloading a trustworthy antivirus app that will prevent suspicious apps from attaching themselves to your phone and secures any public connections you might be using.
Another way to check your phone is to follow these step-by-step processes, depending on the type of phone you use:
Once you have determined that a virus is present on your iPhone or Android device, there are several things you can do.
Caring for your phone is a vital practice to protect your information. Follow these tips to stay safe online and help reduce the risk of your phone getting a virus.
You have come to heavily rely on your smartphones for many online activities and storage of much of your personal data, including contacts, account details, and bank account logins. This puts your devices at high risk of being infected by viruses that impact not just your phone’s performance but also of being compromised by cybercriminals.
To help you protect your device and personal information, the award-winning McAfee Mobile Security solution regularly scans for threats transmitted through suspicious links in text messages, emails or downloads, and blocks them in real time. McAfee Mobile Security is a reputable security application that filters risky emails and phishing attempts so your inbox stays secure, while providing a secure virtual private network. It is also capable of spotting deepfake videos so you can stay ahead of misinformation. With McAfee, you can rest easy knowing your mobile phone is protected from the latest cyberthreats.

We've completed a security evaluation of the Model Context Protocol and discovered several concerning attack patterns relevant to ML practitioners integrating external tools with LLMs.
Background: MCP standardizes how AI applications access external resources - essentially creating a plugin ecosystem for LLMs. While this enables powerful agentic behaviors, it introduces novel security considerations.
Technical Findings:
ML-Specific Implications: For researchers using tools like Claude Desktop or Cursor with MCP servers, these vulnerabilities could lead to:

The modern family juggling act has never been more complex—or more dangerous. If you’re caring for aging parents while raising children, you’re part of what researchers call the “Sandwich Generation.” According to Pew Research, nearly half (47%) of adults in their 40s and 50s find themselves wedged between these dual responsibilities. But in today’s digital landscape, this demographic faces a uniquely modern threat: becoming the primary target of an unprecedented scam epidemic.
As a cybersecurity professional who has witnessed the evolution of online threats over two decades, I can tell you that today’s scam landscape is unlike anything we’ve seen before. The stakes are higher, the tactics more sophisticated, and the Sandwich Generation is squarely in the crosshairs.
McAfee’s recent State of the Scamiverse report paints a troubling picture of digital life in the UK. The statistics are staggering: 60% of Brits report either falling victim to an online scam or knowing someone who has. When these attacks succeed, the financial impact is severe—victims lose an average of £936, with some reporting devastating losses exceeding £7,980.
Perhaps most alarming is the speed at which these crimes unfold. A shocking 68% of victims said it took less than an hour to be defrauded, with 48% reporting that fraud occurred within just 30 minutes of engaging with a scammer. This isn’t the slow-burn con artistry of yesteryear—this is lightning-fast digital predation.
The financial losses, while significant, represent only part of the damage. The psychological impact cuts deeper than many realize. Our research shows that 32% of Brits who fell for online scams experienced moderate to significant distress, including anxiety, depression, and damaged self-esteem. For the Sandwich Generation, already stretched thin emotionally and financially, this psychological burden can be overwhelming.
Consider the compounding effects: 80% of scam victims reported that the experience impacted their self-esteem and ability to trust others. When you’re responsible for protecting not just yourself but also tech-savvy teenagers and digitally-vulnerable parents, this erosion of confidence can have far-reaching consequences for your entire family’s digital safety.
From a cybercriminal’s perspective, the Sandwich Generation represents the perfect storm of vulnerability. Here’s why you’re in their crosshairs:
Overwhelm and Distraction: Scam tactics are most effective when targets are tired, rushed, or mentally overloaded. The constant juggling act of work, children’s needs, and aging parents’ care creates exactly these conditions.
Multiple Attack Vectors: You’re not just protecting yourself—you’re managing the digital lives of three generations. Children who overshare on social media and parents who may trust too readily both create entry points for scammers.
The “Family Tech Lead” Burden: In most households, one person becomes the de facto IT support for everyone. If that’s you, you’re essentially protecting three generations of users with the cybersecurity knowledge and tools designed for one.
Time Poverty: When you’re constantly switching between helping with homework, managing medical appointments, and handling your own responsibilities, the careful scrutiny required to spot sophisticated scams becomes nearly impossible.
The repeat victimization rate is particularly concerning. Once scammers identify a successful target, they often share that information within criminal networks, leading to sustained harassment and repeated attempts.
Protecting Your Children (The Digital Natives)
Despite their technological fluency, young people face unique vulnerabilities:
Social Media Saturation: 28% of 18-24-year-olds receive scam messages via social media platforms. The integration of these platforms into daily life makes detection more challenging.
Gaming Community Exploitation: Scammers infiltrate gaming communities with fake giveaways, cryptocurrency cons, and phishing attempts disguised as game-related communications.
Celebrity Deepfake Scams: AI-generated celebrity endorsements for cryptocurrency schemes or investment opportunities are becoming increasingly sophisticated and harder to detect.
Overconfidence Bias: Young people often believe their digital nativity makes them immune to scams, leading to less cautious behavior online.
Protecting Your Parents (The Trusting Generation)
Older adults face different but equally serious threats:
Email-Based Attacks: 67% of over-55s encounter scams primarily through email, a medium they often trust more than social media.
Authority Impersonation: Tech support scams, fake government communications, and bank impersonation attempts exploit older adults’ respect for authority and institutions.
Voice Cloning Threats: 21% of Brits have encountered AI voice scams impersonating loved ones—a particularly dangerous development for older users who may be more trusting of familiar voices.
Isolation Exploitation: Scammers often target older adults during periods of loneliness or health concerns, when they’re more likely to engage with unexpected communications.
Mobile Device Security
Mobile scams have reached epidemic proportions in the UK, with 35% of Brits falling victim to SMS or call-based scams in the past year. The most common mobile threats include:
Package Delivery Scams (33%): “Your parcel couldn’t be delivered” texts that lead to fake websites designed to steal personal information or payment details.
Subscription Renewal Cons (23%): Messages claiming services like Netflix require payment information updates, leading to credential theft or unauthorized charges.
Social Engineering Openers (16%): Simple “Hey, how are you?” messages that gradually build trust before introducing investment or romance scams.
Computer and Email Security
Email remains the primary attack vector, with 32% of Brits falling victim to phishing attempts last year. The sophistication of these attacks has increased dramatically—while 78% of people believe they can spot scams, today’s emails often perfectly mimic legitimate communications.
Artificial intelligence has revolutionized scamming, with 21% of Brits encountering AI-generated scams. The challenge is significant: 53% of people admit that deepfakes are difficult to spot, and the technology improves daily.
Just as you have a fire escape plan, your family needs a comprehensive fraud response strategy. This should include:
Technology alone cannot solve this crisis. The most effective defense combines good security tools with open family communication and ongoing education. Regular conversations about online safety should be as normal as discussions about physical safety.
For Children: Focus on critical thinking skills rather than fear-based messaging. Teach them to question unexpected opportunities and verify information through multiple sources.
For Parents: Emphasize that asking for help with suspicious communications is a sign of wisdom, not weakness. Create an environment where they feel comfortable seeking guidance.
For Everyone: Establish family rules about financial communications—for example, agreeing that no family member will ever ask for money or personal information via text or email without prior verbal confirmation.
The scam landscape evolves constantly, driven by technological advancement and criminal innovation. As someone who has tracked these trends for two decades, I can tell you that the only constant is change. What worked last year may be ineffective today, and tomorrow will bring new challenges.
The key is building adaptable defenses: security awareness that can evolve with threats, technology solutions that update automatically, and family communication patterns that encourage ongoing vigilance without creating paranoia.
The Sandwich Generation faces unique challenges in today’s digital world, but you’re not powerless. By understanding the threat landscape, implementing appropriate security measures, and fostering open communication about online safety, you can protect your family’s financial security and emotional well-being.
Remember that in the UK today, encountering scam attempts isn’t rare—it’s daily. The goal isn’t to avoid all contact with potential threats but to recognize them quickly and respond appropriately. With the right preparation and tools, you can maintain your family’s digital confidence while staying one step ahead of the scammers.
Your role as the family’s digital guardian is challenging, but it’s also crucial. You’re not just protecting money—you’re protecting your family’s trust, confidence, and peace of mind in an increasingly connected world.
Stay vigilant, stay informed, and remember: when in doubt, pause, check, and verify. Your family’s digital safety depends on it.

Late last year, security researchers made a startling discovery: Kremlin-backed disinformation campaigns were bypassing moderation on social media platforms by leveraging the same malicious advertising technology that powers a sprawling ecosystem of online hucksters and website hackers. A new report on the fallout from that investigation finds this dark ad tech industry is far more resilient and incestuous than previously known.
Image: Infoblox.
In November 2024, researchers at the security firm Qurium published an investigation into “Doppelganger,” a disinformation network that promotes pro-Russian narratives and infiltrates Europe’s media landscape by pushing fake news through a network of cloned websites.
Doppelganger campaigns use specialized links that bounce the visitor’s browser through a long series of domains before the fake news content is served. Qurium found Doppelganger relies on a sophisticated “domain cloaking” service, a technology that allows websites to present different content to search engines compared to what regular visitors see. The use of cloaking services helps the disinformation sites remain online longer than they otherwise would, while ensuring that only the targeted audience gets to view the intended content.
Qurium discovered that Doppelganger’s cloaking service also promoted online dating sites, and shared much of the same infrastructure with VexTrio, which is thought to be the oldest malicious traffic distribution system (TDS) in existence. While TDSs are commonly used by legitimate advertising networks to manage traffic from disparate sources and to track who or what is behind each click, VexTrio’s TDS largely manages web traffic from victims of phishing, malware, and social engineering scams.
Digging deeper, Qurium noticed Doppelganger’s cloaking service used an Internet provider in Switzerland as the first entry point in a chain of domain redirections. They also noticed the same infrastructure hosted a pair of co-branded affiliate marketing services that were driving traffic to sketchy adult dating sites: LosPollos[.]com and TacoLoco[.]co.
The LosPollos ad network incorporates many elements and references from the hit series “Breaking Bad,” mirroring the fictional “Los Pollos Hermanos” restaurant chain that served as a money laundering operation for a violent methamphetamine cartel.
The LosPollos advertising network invokes characters and themes from the hit show Breaking Bad. The logo for LosPollos (upper left) is the image of Gustavo Fring, the fictional chicken restaurant chain owner in the show.
Affiliates who sign up with LosPollos are given JavaScript-heavy “smartlinks” that drive traffic into the VexTrio TDS, which in turn distributes the traffic among a variety of advertising partners, including dating services, sweepstakes offers, bait-and-switch mobile apps, financial scams and malware download sites.
LosPollos affiliates typically stitch these smart links into WordPress websites that have been hacked via known vulnerabilities, and those affiliates will earn a small commission each time an Internet user referred by any of their hacked sites falls for one of these lures.
The Los Pollos advertising network promoting itself on LinkedIn.
According to Qurium, TacoLoco is a traffic monetization network that uses deceptive tactics to trick Internet users into enabling “push notifications,” a cross-platform browser standard that allows websites to show pop-up messages which appear outside of the browser. For example, on Microsoft Windows systems these notifications typically show up in the bottom right corner of the screen — just above the system clock.
In the case of VexTrio and TacoLoco, the notification approval requests themselves are deceptive — disguised as “CAPTCHA” challenges designed to distinguish automated bot traffic from real visitors. For years, VexTrio and its partners have successfully tricked countless users into enabling these site notifications, which are then used to continuously pepper the victim’s device with a variety of phony virus alerts and misleading pop-up messages.
Examples of VexTrio landing pages that lead users to accept push notifications on their device.
According to a December 2024 annual report from GoDaddy, nearly 40 percent of compromised websites in 2024 redirected visitors to VexTrio via LosPollos smartlinks.
On November 14, 2024, Qurium published research to support its findings that LosPollos and TacoLoco were services operated by Adspro Group, a company registered in the Czech Republic and Russia, and that Adspro runs its infrastructure at the Swiss hosting providers C41 and Teknology SA.
Qurium noted the LosPollos and TacoLoco sites state that their content is copyrighted by ByteCore AG and SkyForge Digital AG, both Swiss firms that are run by the owner of Teknology SA, Giulio Vitorrio Leonardo Cerutti. Further investigation revealed LosPollos and TacoLoco were apps developed by a company called Holacode, which lists Cerutti as its CEO.
The apps marketed by Holacode include numerous VPN services, as well as one called Spamshield that claims to stop unwanted push notifications. But in January, Infoblox said they tested the app on their own mobile devices, and found it hides the user’s notifications, and then after 24 hours stops hiding them and demands payment. Spamshield subsequently changed its developer name from Holacode to ApLabz, although Infoblox noted that the Terms of Service for several of the rebranded ApLabz apps still referenced Holacode in their terms of service.
Incredibly, Cerutti threatened to sue me for defamation before I’d even uttered his name or sent him a request for comment (Cerutti sent the unsolicited legal threat back in January after his company and my name were merely tagged in an Infoblox post on LinkedIn about VexTrio).
Asked to comment on the findings by Qurium and Infoblox, Cerutti vehemently denied being associated with VexTrio. Cerutti asserted that his companies all strictly adhere to the regulations of the countries in which they operate, and that they have been completely transparent about all of their operations.
“We are a group operating in the advertising and marketing space, with an affiliate network program,” Cerutti responded. “I am not [going] to say we are perfect, but I strongly declare we have no connection with VexTrio at all.”
“Unfortunately, as a big player in this space we also get to deal with plenty of publisher fraud, sketchy traffic, fake clicks, bots, hacked, listed and resold publisher accounts, etc, etc.,” Cerutti continued. “We bleed lots of money to such malpractices and conduct regular internal screenings and audits in a constant battle to remove bad traffic sources. It is also a highly competitive space, where some upstarts will often play dirty against more established mainstream players like us.”
Working with Qurium, researchers at the security firm Infoblox released details about VexTrio’s infrastructure to their industry partners. Just four days after Qurium published its findings, LosPollos announced it was suspending its push monetization service. Less than a month later, Adspro had rebranded to Aimed Global.
A mind map illustrating some of the key findings and connections in the Infoblox and Qurium investigations. Click to enlarge.
In March 2025, researchers at GoDaddy chronicled how DollyWay — a malware strain that has consistently redirected victims to VexTrio throughout its eight years of activity — suddenly stopped doing that on November 20, 2024. Virtually overnight, DollyWay and several other malware families that had previously used VexTrio began pushing their traffic through another TDS called Help TDS.
Digging further into historical DNS records and the unique code scripts used by the Help TDS, Infoblox determined it has long enjoyed an exclusive relationship with VexTrio (at least until LosPollos ended its push monetization service in November).
In a report released today, Infoblox said an exhaustive analysis of the JavaScript code, website lures, smartlinks and DNS patterns used by VexTrio and Help TDS linked them with at least four other TDS operators (not counting TacoLoco). Those four entities — Partners House, BroPush, RichAds and RexPush — are all Russia-based push monetization programs that pay affiliates to drive signups for a variety of schemes, but mostly online dating services.
“As Los Pollos push monetization ended, we’ve seen an increase in fake CAPTCHAs that drive user acceptance of push notifications, particularly from Partners House,” the Infoblox report reads. “The relationship of these commercial entities remains a mystery; while they are certainly long-time partners redirecting traffic to one another, and they all have a Russian nexus, there is no overt common ownership.”
Renee Burton, vice president of threat intelligence at Infoblox, said the security industry generally treats the deceptive methods used by VexTrio and other malicious TDSs as a kind of legally grey area that is mostly associated with less dangerous security threats, such as adware and scareware.
But Burton argues that this view is myopic, and helps perpetuate a dark adtech industry that also pushes plenty of straight-up malware, noting that hundreds of thousands of compromised websites around the world every year redirect victims to the tangled web of VexTrio and VexTrio-affiliate TDSs.
“These TDSs are a nefarious threat, because they’re the ones you can connect to the delivery of things like information stealers and scams that cost consumers billions of dollars a year,” Burton said. “From a larger strategic perspective, my takeaway is that Russian organized crime has control of malicious adtech, and these are just some of the many groups involved.”
As KrebsOnSecurity warned way back in 2020, it’s a good idea to be very sparing in approving notifications when browsing the Web. In many cases these notifications are benign, but as we’ve seen there are numerous dodgy firms that are paying site owners to install their notification scripts, and then reselling that communications pathway to scammers and online hucksters.
If you’d like to prevent sites from ever presenting notification requests, all of the major browser makers let you do this — either across the board or on a per-website basis. While it is true that blocking notifications entirely can break the functionality of some websites, doing this for any devices you manage on behalf of your less tech-savvy friends or family members might end up saving everyone a lot of headache down the road.
To modify site notification settings in Mozilla Firefox, navigate to Settings, Privacy & Security, Permissions, and click the “Settings” tab next to “Notifications.” That page will display any notifications already permitted and allow you to edit or delete any entries. Tick the box next to “Block new requests asking to allow notifications” to stop them altogether.
In Google Chrome, click the icon with the three dots to the right of the address bar, scroll all the way down to Settings, Privacy and Security, Site Settings, and Notifications. Select the “Don’t allow sites to send notifications” button if you want to banish notification requests forever.
In Apple’s Safari browser, go to Settings, Websites, and click on Notifications in the sidebar. Uncheck the option to “allow websites to ask for permission to send notifications” if you wish to turn off notification requests entirely.
Hey all, started a blog series on Vulnerability Management. 4 articles posted already the last one is about when open you open the flood gate of a code or cloud scanner and you start drowning in findings!
This leads to thousands of findings for an SMB, millions for a big org. But vulns can’t all be worth fixing, right? This article walks through a first, simple way to shorten the list. Which is to triage every vuln and confirm if the bug is reachable in your reality.
Let me know if you have any comment to improve the blog or this article, would appreciate it!
This is a walkthrough video for anyone who wants to run Kali Linux in a more lightweight, consistent way using Docker.
The video covers: * Installing Kali Linux via Docker * Avoiding the "it works on my machine" issue * Creating your own custom Docker image * Setting up file share between host and container
It's a solid way to practice hacking without spinning up a whole VM — and great for anyone doing tutorials that require a Kali Linux instance, or folks who are starting out their penetration testing or bug bounty journey.
Microsoft today released security updates to fix at least 67 vulnerabilities in its Windows operating systems and software. Redmond warns that one of the flaws is already under active attack, and that software blueprints showing how to exploit a pervasive Windows bug patched this month are now public.
The sole zero-day flaw this month is CVE-2025-33053, a remote code execution flaw in the Windows implementation of WebDAV — an HTTP extension that lets users remotely manage files and directories on a server. While WebDAV isn’t enabled by default in Windows, its presence in legacy or specialized systems still makes it a relevant target, said Seth Hoyt, senior security engineer at Automox.
Adam Barnett, lead software engineer at Rapid7, said Microsoft’s advisory for CVE-2025-33053 does not mention that the Windows implementation of WebDAV is listed as deprecated since November 2023, which in practical terms means that the WebClient service no longer starts by default.
“The advisory also has attack complexity as low, which means that exploitation does not require preparation of the target environment in any way that is beyond the attacker’s control,” Barnett said. “Exploitation relies on the user clicking a malicious link. It’s not clear how an asset would be immediately vulnerable if the service isn’t running, but all versions of Windows receive a patch, including those released since the deprecation of WebClient, like Server 2025 and Windows 11 24H2.”
Microsoft warns that an “elevation of privilege” vulnerability in the Windows Server Message Block (SMB) client (CVE-2025-33073) is likely to be exploited, given that proof-of-concept code for this bug is now public. CVE-2025-33073 has a CVSS risk score of 8.8 (out of 10), and exploitation of the flaw leads to the attacker gaining “SYSTEM” level control over a vulnerable PC.
“What makes this especially dangerous is that no further user interaction is required after the initial connection—something attackers can often trigger without the user realizing it,” said Alex Vovk, co-founder and CEO of Action1. “Given the high privilege level and ease of exploitation, this flaw poses a significant risk to Windows environments. The scope of affected systems is extensive, as SMB is a core Windows protocol used for file and printer sharing and inter-process communication.”
Beyond these highlights, 10 of the vulnerabilities fixed this month were rated “critical” by Microsoft, including eight remote code execution flaws.
Notably absent from this month’s patch batch is a fix for a newly discovered weakness in Windows Server 2025 that allows attackers to act with the privileges of any user in Active Directory. The bug, dubbed “BadSuccessor,” was publicly disclosed by researchers at Akamai on May 21, and several public proof-of-concepts are now available. Tenable’s Satnam Narang said organizations that have at least one Windows Server 2025 domain controller should review permissions for principals and limit those permissions as much as possible.
Adobe has released updates for Acrobat Reader and six other products addressing at least 259 vulnerabilities, most of them in an update for Experience Manager. Mozilla Firefox and Google Chrome both recently released security updates that require a restart of the browser to take effect. The latest Chrome update fixes two zero-day exploits in the browser (CVE-2025-5419 and CVE-2025-4664).
For a detailed breakdown on the individual security updates released by Microsoft today, check out the Patch Tuesday roundup from the SANS Internet Storm Center. Action 1 has a breakdown of patches from Microsoft and a raft of other software vendors releasing fixes this month. As always, please back up your system and/or data before patching, and feel free to drop a note in the comments if you run into any problems applying these updates.
