“Your device has been blocked due to illegal activity” Blocks Your Mobile? Is it Real?

“Your device has been blocked due to illegal activity” warning alert is a scam notification caused by malware, ransowmare and scareware. It has been categorized in a virus list which has the same feature or symptom as FBI virus, FBI Prism virus, FBI cyber crime virus, or Metropolitan British virus, AFP virus etc. It locks up vicitims’s mobile devices for ridiculous reasons and ask for a ransom to unlock mobile device. Cyber criminals use different malicious files like malware, ransomware and sacreware to pop up this scaring warning message and force people into believing that the only way to unlock their mobile device is to make a fine payment or ransom of $100-$500 or £100-£200. This kind of blocking warning message is mostly associated with ransowmare which is a type of malicious software that blocks access to the victim’s data or threatens to publish or delete it until a ransom is paid. So this ransowmare usually pretends to be law enforecement, government department or police agency or other judicial institutions like FBI Cyber Crime department, FBI Prism, ICSPA, British Metropolitan Police, PCeU, Australia Federal Police to display this kind of fake message and falsely accused victims of watching and distributing illegal materials especially pornographic contents even though victims had never done these activities. Cyber criminal distributes this ransowmare to different countries and regions and the ransomware blocks the victims’ devices with different interfaces but with the same bogus warning notice “Your device has been blocked due to illegal activity”.

This ransowmare can attack and infect a wide range of different brand mobile devices based on Android and iOS like Samsung Galaxy, LG, Motorola, Huawei, HTC phone and tablet, iPhone, iPad and iPod Touch. When mobile users are surfing on the Internet, it uses the Javascript to hijack your browser like Internet, Browser, Chrome, Safari or Firefox first then pops up this “Your device has been blocked due to illegal activity” warning message, next it will soon force installing unwanted malicious files into the mobile system to totally lock your mobile. Once your mobile device is locked up, you will find that the browser can’t be shut down or you can’t do anything with your mobile because all buttons don’t work. You will not be able to shut down or restart your mobile but just see this warning notice hanging there. To quickly get your money, it threatens you that you have to submit the fine payment within limited time or all your data will be deleted, your criminal case will be transferred to court or certain judicial department, and you will be caught by the police or taken into the jail. When some inexperienced victims find this warning message, they think it’s real as the logo, name and badge of law enforcement and police agency is there and warning message looks more genuine. Many victims worry bad records left in police even serving into jail, they soon give the fine payment or so-called ransom as this ransomware requests. “Your device has been blocked due to illegal activity” warning is a big hoax to extort people out of money. Even though you send the penalty, your mobile is still locked up.
