Scary movies are great. Scary mobile threats, not so much.
Ghosts, killer clowns, and the creatures can stir up all sorts of heebie-jeebies. The fun kind. Yet mobile threats like spyware, living dead apps, and botnets can conjure up all kinds of trouble.
Let’s get a rundown on the top mobile threats — then look at how you can banish them from your phone.
“I Know What You Did Because of Spyware”
Spyware is a type of malware that lurks in the shadows of your trusted device, collecting information around your browsing habits, personal information and more. Your private information is then sent to third parties, without your knowledge. Spooky stuff.
“Dawn of the Dead Apps”
Think haunted graveyards only exist in horror movies? Think again! Old apps lying dormant on your phones are like app graveyards, Many of these older apps may no longer be supported by Google or Apple stores. Lying there un-updated, these apps might harbor vulnerabilities. And that can infect your device with malware or leak your data to a third party.
“Bone Chilling Botnets”
Think “Invasion of the Body Snatchers,” but on your mobile device. What is a botnet you ask? When malware infiltrates a mobile device (like through a sketchy app) the device becomes a “bot.” This bot becomes one in an army of thousands of infected internet-connected devices. From there, they spread viruses, generate spam, and commit sorts of cybercrime. Most mobile device users aren’t even aware that their gadgets are compromised, which is why protecting your device before an attack is so important.
“Malicious Click or Treat”
Clicking links and mobile devices go together like Frankenstein and his bride. Which is why ad and click fraud through mobile devices is becoming more prevalent for cybercriminals. Whether through a phishing campaign or malicious apps, hackers can gain access to your device and your private information. Always remember to click with caution.
“IoT Follows”
The Internet of Things (IoT) has quickly become a staple in our everyday lives, and hackers are always ready to target easy prey. Most IoT devices connect to mobile devices, so if a hacker can gain access to your smartphone, they can infiltrate your connected devices as well. Or vice versa.
1) Avoid third-party app stores. Unlike Google Play and Apple’s App Store, which have measures in place to review and vet apps to help ensure that they are safe and secure, third-party sites may very well not. Further, some third-party sites may intentionally host malicious apps as part of a broader scam.
Granted, hackers have found ways to work around Google and Apple’s review process, yet the chances of downloading a safe app from them are far greater than anywhere else. Further, both Google and Apple are quick to remove malicious apps once discovered, making their stores that much safer.
2) Review with a critical eye. As with so many attacks, hackers rely on people clicking links or tapping “download” without a second thought. Before you download, take time to do some quick research. That may uncover some signs that the app is malicious. Check out the developer—have they published several other apps with many downloads and good reviews? A legit app typically has quite a few reviews, whereas malicious apps may have only a handful of (phony) five-star reviews.
Lastly, look for typos and poor grammar in both the app description and screenshots. They could be a sign that a hacker slapped the app together and quickly deployed it.
3) Go with a strong recommendation. Yet better than combing through user reviews yourself is getting a recommendation from a trusted source, like a well-known publication or from app store editors themselves. In this case, much of the vetting work has been done for you by an established reviewer. A quick online search like “best fitness apps” or “best apps for travelers” should turn up articles from legitimate sites that can suggest good options and describe them in detail before you download.
4) Keep an eye on app permissions. Another way hackers weasel their way into your device is by getting permission to access things like your location, contacts, and photos—and they’ll use sketchy apps to do it. (Consider the long-running free flashlight app scams mentioned above that requested up to more than 70 different permissions, such as the right to record audio, and video, and access contacts.
So check and see what permissions the app is requesting. If it’s asking for way more than you bargained for, like a simple game wanting access to your camera or microphone, it may be a scam. Delete the app and find a legitimate one that doesn’t ask for invasive permissions like that. If you’re curious about permissions for apps that are already on your phone, iPhone users can learn how to allow or revoke app permission here, and Android can do the same here.
5) Get scam protection. Plenty of scams find your phone by way of sketchy links sent in texts, messages, and emails. Our Text Scam Detector can block them before they do you any harm. And if you tap that link by mistake, Scam Protection still blocks it.
6) Protect your smartphone with security software. With all that we do on our phones, it’s important to get security software installed on them, just like we install it on our computers and laptops. Whether you go with comprehensive security software that protects all of your devices or pick up an app in Google Play or Apple’s App Store, you’ll have malware, web, and device security that’ll help you stay safe on your phone.

Social engineering. It’s a con game. And a con game by any other name stings just as badly.
Like any form of con, social engineering dupes their victims by playing on their emotions. Fear, excitement, and surprise. And they prey on human nature as well. The desire to help others, recognizing authority, and even the dream of hitting it big in the lottery. All of this comes into play in social engineering.
By design, the scammers who employ social engineering do so in an attempt to bilk people out of their personal information, their money, or both. More broadly, they’re designed to give scammers access—to a credit card, bank account, proprietary company information, and even physical access to a building or restricted space in the case of tailgating attacks. In this way, social engineering is an attack technique rather than a specific type of attack.
Several types of attacks employ social engineering:
The list goes on. Yet those are among the top attacks that use social engineering as a means of hoodwinking their victims. It’s a scammer’s secret weapon. Time and time again, we’ve seen just how effective it can be.
So while many bad actors turn to social engineering tricks to do their dirty work, they share several common characteristics. That makes them easy to spot. If you know what you’re looking for.
An overexcited or aggressive tone in an email, text, DM, or any kind of message you receive should put up a big red flag. Scammers use these scare tactics to get you to act without thinking things through first.
Common examples include imposter scams. The scammer will send a text or email that looks like it comes from someone you know. And they’ll say they’re in a jam of some sort, like their car has broken down in the middle of nowhere, or that they have a medical emergency and to go to urgent care. In many of these cases, scammers will quickly ask for money.
Another classic is the tax scam, where a scammer poses as a tax agent or representative. From there, they bully money out of their victims with threats of legal action or even arrest. Dealing with an actual tax issue might be uncomfortable, but a legitimate tax agent won’t threaten you like that.
You’ve won a sweepstakes! (That you never entered.) Get a great deal on this hard-to-find item! (That will never ship after you’ve paid for it.) Scammers will concoct all kinds of stories to separate you from your personal information.
The scammers behind bogus prizes and sweepstakes will ask you for banking information or sometimes even your tax ID number to pay out your winnings. Winnings you’ll never receive, of course. The scammer wants that information to raid your accounts and commit all kinds of identity theft.
Those great deals? The scammers might not ship them at all. They’ll drain your credit or debit card instead and leave you tapping your foot by your mailbox. Sometimes, the scammers might indeed ship you something after all—a knock-off item. One possibly made with child labor.
Scammers will often pose as people you know. That can include friends, family members, co-workers, bosses, vendors or clients at work, and so on. And when they do, something about the message you get will seem a bit strange.
For starters, the message might not sound like it came from them. What they say and how they say it seems off or out of character. It might include links or attachments you didn’t expect to get. Or the message might come to you via a DM sent from a “new” account they set up. In the workplace, you might get a message from your boss instructing you to pay someone a large sum from the company account.
These are all signs that something scammy might be afoot. You’ll want to follow up with these people in person or with a quick phone call just to confirm. Reach them in any way other than by replying to the message you received. Even if it looks like a legitimate account. There’s the chance their account was hacked.
How do scammers know how to reach you in the first place? And how do they seem to know just enough about you to cook up a convincing story? Clever scammers have resources, and they’ll do their homework. You can give them far less to work with by taking the following steps.
Online data brokers hoard all kinds of personal information about individuals. And they’ll sell it to anyone. That includes scammers. Data brokers gather it from multiple sources, such as public records and third parties that have further information like browsing histories and shopping histories (think your supermarket club card). With that information, a scammer can sound quite convincing—like they know you in some way or where your interests lie. You can get this information removed so scammers can’t get their hands on it. Our Personal Data Cleanup scans some of the riskiest data broker sites and shows you which ones are selling your personal info. It also provides guidance on how you can remove your data from those sites and with select products, it can even manage the removal for you.
Needless to say, social media says a lot about you and what you’re into. You already know that because you put a part of yourself out there with each post—not to mention a record of the groups, pages, and things that you follow or like. All this provides yet more grist for a scammer’s mill when it comes time for them to concoct their stories. Setting your accounts to private takes your posts out of the public eye, and the eye of potential scammers too. This can help reduce your risk of getting conned.
Scammers throw all kinds of bogus links at people in the hope they’ll click and wind up on their scammy websites. They’ll also send attachments loaded with malware—a payload that contains ransomware, spyware, or viruses. If you get a message about one of your accounts, a shipment, or anything that involves your personal or financial info, confirm the sender. Did the message come from a legitimate address or account? Or was the address spoofed or the account a fake? For example, some scammers create social media accounts to pose as the U.S. Internal Revenue Service (IRS). The IRS doesn’t contact people through social media. If you have a concern about a message or account, visit the site in question by typing it in directly instead of clicking on the link in the message. Access your information from there or call their customer service line.
The combination of these two things makes it tough for scammers to crack your accounts. Even if they somehow get hold of your password, they can’t get into your account without the multifactor authentication number (usually sent to your phone in some form). A password manager as part of comprehensive online protection software can help you create and securely store those strong, unique passwords. Also, never give your authentication number to anyone after you receive it. Another common scammer trick is to masquerade as a customer service rep and ask you to send that number to them.
This is the one piece of advice scammers don’t want you to have, let alone follow. They count on you getting caught up in the moment—the emotion of it all. Once again, emotions, urgency, and human nature are all key components in any social engineering con. The moment you stop and think about the message, what it’s asking of you, and the way it’s asking you for it, will often quickly let you know that something is not quite right. Follow up. A quick phone call or face-to-face chat can help you from getting conned.

Anyone can try ChatGPT for free. Yet that hasn’t stopped scammers from trying to cash in on it.
A rash of sketchy apps have cropped up in Apple’s App Store and Google Play. They pose as Chat GPT apps and try to fleece smartphone owners with phony subscriptions.
Yet you can spot them quickly when you know what to look for.
ChatGPT is an AI-driven chatbot service created by OpenAI. It lets you have uncannily human conversations with an AI that’s been programmed and fed with information over several generations of development. Provide it with an instruction or ask it a question, and the AI provides a detailed response.
Unsurprisingly, it has millions of people clamoring to use it. All it takes is a single prompt, and the prompts range far and wide.
People ask ChatGPT to help them write cover letters for job interviews, make travel recommendations, and explain complex scientific topics in plain language. One person highlighted how they used ChatGPT to run a tabletop game of Dungeons & Dragons for them. (If you’ve ever played, you know that’s a complex task that calls for a fair share of cleverness to keep the game entertaining.)
That’s just a handful of examples. As for myself, I’ve been using ChatGPT in the kitchen. My family and I have been digging into all kinds of new recipes thanks to its AI.
So, where do the scammers come in?
Scammers, have recently started posting copycat apps that look like they are powered by ChatGPT but aren’t. What’s more, they charge people a fee to use them—a prime example of fleeceware. OpenAI, the makers of ChatGPT, have just officially launched their iOS app for U.S. iPhone users and can be downloaded from the Apple App Store here. The official Android version is still yet to be released.
Fleeceware mimics a pre-existing service that’s free or low-cost and then charges an excessive fee to use it. Basically, it’s a copycat. An expensive one at that.
Fleeceware scammers often lure in their victims with “a free trial” that quickly converts into a subscription. However, with fleeceware, the terms of the subscription are steep. They might bill the user weekly, and at rates much higher than the going rate.
The result is that the fleeceware app might cost the victim a few bucks before they can cancel it. Worse yet, the victim might forget about the app entirely and run up hundreds of dollars before they realize what’s happening. Again, all for a simple app that’s free or practically free elsewhere.
What makes fleeceware so tricky to spot is that it can look legit at first glance. Plenty of smartphone apps offer subscriptions and other in-app purchases. In effect, fleeceware hides in plain sight among the thousands of other legitimate apps in the hopes you’ll download it.
With that, any app that charges a fee to use ChatGPT is fleeceware. ChatGPT offers basic functionality that anyone can use for free.
There is one case where you might pay a fee to use ChatGPT. It has its own subscription-level offering, ChatGPT Plus. With a subscription, ChatGPT responds more quickly to prompts and offers access during peak hours when free users might be shut out. That’s the one legitimate case where you might pay to use it.
In all, more and more people want to take ChatGPT for a spin. However, they might not realize it’s free. Scammers bank on that, and so we’ve seen a glut of phony ChatGPT apps that aim to install fleeceware onto people’s phones.
Read the description of the app and see what the developer is really offering. If the app charges you to use ChatGPT, it’s fleeceware. Anyone can use ChatGPT for free by setting up an account at its official website, https://chat.openai.com.
Reviews can tell you quite a bit about an app. They can also tell you the company that created it handles customer feedback.
In the case of fleeceware, you’ll likely see reviews that complain about sketchy payment terms. They might mention three-day trials that automatically convert to pricey monthly or weekly subscriptions. Moreover, they might describe how payment terms have changed and become more costly as a result.
In the case of legitimate apps, billing issues can arise from time to time, so see how the company handles complaints. Companies in good standing will typically provide links to customer service where people can resolve any issues they have. Company responses that are vague, or a lack of responses at all, should raise a red flag.
Scammers are smart. They’ll count on you to look at an overall good review of 4/5 stars or more and think that’s good enough. They know this, so they’ll pack their app landing page with dozens and dozens of phony and fawning reviews to make the app look legitimate. This tactic serves another purpose: it hides the true reviews written by actual users, which might be negative because the app is a scam.
Filter the app’s reviews for the one-star reviews and see what concerns people have. Do they mention overly aggressive billing practices, like the wickedly high prices and weekly billing cycles mentioned above? That might be a sign of fleeceware. Again, see if the app developer responded to the concerns and note the quality of the response. A legitimate company will honestly want to help a frustrated user and provide clear next steps to resolve the issue.
Google Play does its part to keep its virtual shelves free of malware-laden apps with a thorough submission process, as reported by Google. It further keeps things safer through its App Defense Alliance that shares intelligence across a network of partners, of which we’re a proud member. Further, users also have the option of running Play Protect to check apps for safety before they’re downloaded. Apple’s App Store has its own rigorous submission process for submitting apps. Likewise, Apple deletes hundreds of thousands of malicious apps from its store each year.
Third-party app stores might not have protections like these in place. Moreover, some of them might be fronts for illegal activity. Organized cybercrime organizations deliberately populate their third-party stores with apps that steal funds or personal information. Stick with the official app stores for the most complete protection possible.
Many fleeceware apps deliberately make it tough to cancel them. You’ll often see complaints about that in reviews, “I don’t see where I can cancel my subscription!” Deleting the app from your phone is not enough. Your subscription will remain active unless you cancel your payment method.
Luckily, your phone makes it easy to cancel subscriptions right from your settings menu. Canceling makes sure your credit or debit card won’t get charged when the next billing cycle comes up.
Be wary. Many fleeceware apps have aggressive billing cycles. Sometimes weekly.
ChatGPT is free. Anyone can use it by setting up a free account with OpenAI at https://chat.openai.com. Smartphone apps that charge you to use it are a scam.
You can download the official app, currently on iOS from the App Store
