The WinLock2 Ransomware is a Trojan that locks your screen and creates fake police warnings specific to the Czech Republic. Although the Trojan uses various methods of blocking your screen while awaiting its ransom, malware experts recommend ignoring the demands, which aren't mandatory for restoring your PC. Follow the instructions in this article for disabling the Trojan's UI before letting your anti-malware software handle uninstalling the WinLock2 Ransomware.

The Scurvy on Your Screen from Attempted Software Piracy

Cybercrooks managing Trojan campaigns often are no less aware than marketing teams of what constitutes a worthy psychological tool for promoting a product. Although spam e-mails using a business-themed disguise are preferable for targeting corporate servers, Trojans with casual victims in mind often install themselves by pretending to be popular media. Such is the case with the WinLock2 Ransomware's campaign, which is more typical to the attacks of years ago, before the widespread adoption of encryption payloads.

The WinLock2 Ransomware is Windows software that circulates on piracy-related websites and networks, such as torrents, to compromise victims at random. Its installer's name misrepresents it as a crack for one of the new entries of the Call of Duty franchise, including a tag associated with a known hacker organization. When the user makes the mistake of launching it, the WinLock2 Ransomware makes Registry changes for persisting on the system, disables the Windows Task Manager, and loads a screen-sized pop-up.

The window displays full-screen without a border or any UI options for minimizing, closing or resizing it. This pop-up claims that the user's PC is under a blockade for its history with illicit activities (such as breaching copyright related to media like the previously-noted CoD) until they fulfill a PaySafeCard fee. While the text is in Czech, malware analysts also identify other campaigns using identical components with different languages, especially throughout Europe and North America.

Cracking a Fake Cracker

DRM-cracking software, key generators, and other, traditionally illicit programs are often associating with other, unsafe activity that may take advantage of their users, as much as any business entities. Even though the WinLock2 Ransomware's disguise is superficial and it has no endorsement from the Czech government, its attacks can disable your security applications and eliminate any access to the basic Windows interface. The monitor-unlocking tactics that our malware analysts recommend include:

  • Entering any sixteen-character-length string (such as '123456789abcdefg') should remove the WinLock2 Ransomware's window.
  • You also may restart your computer by booting it from a removable device, such as any DVD or USB.

In either case, the victim should have anti-malware products deleting all of the WinLock2 Ransomware's components before restarting their computers. The ransom should, as with any extortion-based Trojan, be left unpaid.

There are no legal repercussions from the WinLock2 Ransomware infection. However, breaking the law has a way of endangering the aggressor as much as any victims, even if the result is a coincidental, third-party threat, like the WinLock2 Ransomware.
