What is Your Device Has Been Blocked?
'Your Device Has Been Blocked' is a fake pop-up error message displayed by malicious websites. Note that it only targets the Mac OS. Users often visit these malicious websites inadvertently, without their consent - they are redirected by various potentially unwanted programs (PUPs). These apps usually infiltrate systems without permission ('bundling' method). As well as causing unwanted redirects, PUPs also deliver intrusive online advertisements and gather various information relating to users' Internet browsing activity.
This error message states that suspicious activity has been detected and that personal details (banking information, logins/passwords, etc.) are at risk. It states that, as a result, the system has been blocked. This same message is also played via the computer speakers. To remove this malware, victims are encouraged to contact certified technicians via a telephone number ('+1-866-811-0525', '+44-800-090-3856') provided. They will then supposedly receive help in solving this issue. Be aware, however, that 'Your Device Has Been Blocked' is a scam. This fake message is merely an attempt to scare and trick victims into calling and paying for technical services that are not required. Cyber criminals generate revenue by tricking unsuspecting users. Therefore, never attempt to contact these people. You can remove this error simply by closing the web browser. As mentioned above, PUPs also deliver intrusive online advertisements - developers employ a 'virtual layer' (a tool that enables placement of third party graphical content on any site). The displayed ads (pop-ups, coupons, banners, etc) often conceal underlying website content, significantly diminishing the web browsing experience. In addition, the ads often redirect to malicious websites and even accidental clicks can result in high-risk computer infections. Furthermore, potentially unwanted programs track Internet browsing activity by collecting IP addresses, search queries, URLs visited, pages viewed, geo-locations, mouse/keyboard activity, and other similar information. The data might contain personally identifiable details that developers share with cooperating third parties (potentially, cyber criminals) who misuse private details to generate revenue. Therefore, data tracking can result in serious privacy issues or even identity theft. All PUPs must be uninstalled immediately.
There are many fake errors similar to 'Your Device Has Been Blocked'. The list of examples includes (but is not limited to) Critical Security Warning!, YOUR APPLE COMPUTER HAS BEEN LOCKED, and Immediately Call Apple Support. All claim that system is damaged in certain way, however, as with 'Your Device Has Been Blocked', these pop-ups are also designed to trick users and, thus, they should never be trusted. Potentially unwanted programs are designed only to generate revenue for the developers. By delivering promises to enhance the web browsing experience, they attempt to give the impression of legitimacy, however, rather than providing any value for regular users, PUPs cause unwanted redirects, deliver intrusive ads, and continually record personal data.
