Do not trust websites claiming "YOUR DEVICE MAY BE COMPROMISED"

Damage level: Medium

What kind of scam is "YOUR DEVICE MAY BE COMPROMISED"?

While investigating sites that utilize rogue advertising networks, our researchers discovered the "YOUR DEVICE MAY BE COMPROMISED" scam. It uses scare tactics to trick users into performing specific actions. Typically, scams of this ilk promote untrustworthy and harmful software.



When we accessed a webpage running this scam, it displayed a pop-up window claiming that the visitor's device may be compromised.

The background page insistently warned the user of potential malware infections and other threats such as malicious websites, hackers, etc. The scam reassured the visitor that they could solve this within seconds by running a powerful application to clean and protect their device. The page also depicted a countdown clock to create an impression of urgency.

After we clicked the "Clean my Device" button, the webpage prompted us to permit its browser notification delivery (spam notifications). When we clicked "Allow", the page redirected us to a nonfunctional website. However, this could be rectified by the scammers. Furthermore, redirects may be impacted by factors like user geolocation.

In most cases, scams of this kind endorse fake anti-virus tools, adware, browser hijackers, PUAs, and other dubious software. In rare instances, these schemes proliferate trojans, ransomware, and other malware. Alternatively, scams can redirect to the official sites of genuine products/services. This is due to the scammers abusing the content's affiliate programs to acquire illegitimate commissions for the promotion.

To summarize, victims of scams like "YOUR DEVICE MAY BE COMPROMISED" can experience system infections, severe privacy issues, financial losses, and even identity theft.

Similar scam examples

We have inspected thousands of scams; "Total AV Security - Your Smartphone Is Infected", "Your AVAST AntiVirus License Has Expired!", "Your Identity Has Been Stolen!", and "TROJAN_2023 And Other Viruses Detected (5)" are merely some examples of ones similar to "YOUR DEVICE MAY BE COMPROMISED".

Various deceptive claims are used by harmful online content to trick victims into downloading/installing software, purchasing products, disclosing sensitive information, making monetary transactions, etc. Online scams can be riddled with errors, use basic graphics, or be competently disguised as messages/warnings from legitimate service providers or other entities.

Due to how widespread deceptive and malicious material is on the Web – we strongly recommend exercising caution while browsing.

How did I open a scam website?

Deceptive websites can be force-opened the moment a page that uses rogue advertising networks is accessed. Alternatively, the latter can generate redirects to scam sites once hosted content is interacted with (e.g., clicking buttons, text input fields, ads, links, etc.).

Spam browser notifications and intrusive advertisements are also used to promote scams. Misspelling a website's URL can result in a redirect (or a redirection chain leading) to a deceptive page. Additionally, adware can display scam-promoting ads or generate redirects to sites hosting this content.

How to avoid visiting scam websites?

We strongly advise against visiting/using websites that employ rogue advertising networks; this includes sites offering pirated content or other questionable services (e.g., Torrenting, illegal streaming/downloading, etc.). We recommend paying attention to URLs and entering them with care.

To avoid receiving undesirable browser notifications – do not enable suspicious pages to deliver them (i.e., do not click "Allow", "Allow Notifications", etc.). Instead, ignore or deny notification delivery requests from such webpages (i.e., press "Block", "Block Notifications", etc.).

Furthermore, downloads must be performed from official/verified sources, and installation processes must be treated with caution (e.g., by reading terms, using "Custom/Advanced" settings, and opting out of all supplementary apps, extensions, tools, etc.) – to prevent bundled/harmful software from infiltrating the device.

If your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate all threats.

How to identify a pop-up scam?

Pop-up windows with various fake messages are a common type of lures cybercriminals use. They collect sensitive personal data, trick Internet users into calling fake tech support numbers, subscribe to useless online services, invest in shady cryptocurrency schemes, etc.

While in the majority of cases these pop-ups don't infect users' devices with malware, they can cause direct monetary loss or could result in identity theft.
