Data Recovery ToolWindows Data Recovery by Stellar Phoenix Notice! This product scans your drive sectors to recover lost files and it may not recover 100% of the encrypted files, but only few of them, depending on the situation and whether or not you have reformatted your drive.

We have seen ransomware going through new development stages. As a result, latest ransomware pieces become more and more sophisticated and exceed even the boldest of expectations. In that sense, the appearance of the ScreenLocker ransom threat shouldn’t be of any surprise. Some security researchers even believe that ScreenLocker has been created with the sole purpose to test new possibilities of ransom software. Another explanation for the peculiar features of ScreenLocker is that it is still in a development stage.

ScreenLocker Novel Features. Comparison with Other Ransomware

Typically, ransomware threats such as CryptoLocker and CryptoWall, encrypt personal files on the targeted system, and seek payment so that the decryption key is obtained. However, ScreenLocker infections are quite different.

Once a PC is infected, ScreenLocker will block any system executable files, and prevents the user from accessing the Task Manager and Windows Registry. To restore access to these locations, the victim will have to delete a value dubbed RealtekSoftware. The value location is:

→ HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

Nonetheless, ScreenLocker locks the system’s screen and prevent the user from initiating any actions. Even though the threat is ransomware by nature, it doesn’t display any ransom message with payment instructions. Instead, the user will be asked to participate in an online survey.

Important!

If the user is tricked and decides to follow the link provided in the ransom message, he may just give away valuable information. The whole infection may be nothing more than some ‘ransomware research’.

This is the screen alert displayed by ScreenLocker that is either in English:


We have detected that the software running on your computer is not genuine, please complete an offer below to unlock the computer permanently and insert the key below that will be provided after complete supply.
To get the key, complete a survey by clicking HERE.

This is what the message should look like in Spanish:


Su copia de software no es genuina.
Hemos detectado que el software que corre en su ordenador no es genuino, por favor complete una oferta a continuacion para desbloquear el equipo de forma permanente e inserte la llave a continuacion que le sera proporcionada tras completer la oferta.
To get the key, complete a survey by clicking HERE.

As visible by the message, ScreenLocker alleges the user of having counterfeit software running on his system. Even if that claim is right, users shouldn’t follow any instructions given by the cyber criminals. As we already said, the hacking team can only be attempting to obtain valuable information for their ‘ransomware research’.

What users are advised to do is run powerful anti-malware software to remove the threat immediately.

Also, we have compiled several prevention tips that should become your online security handbook. Not following them may have brought ScreenLocker in the first place.

Ransomware Prevention & Security Tips

  • Use additional firewall protection.
  • Always apply administrative control over your programs.
  • Improve your passwords and store them in a safe place, preferably outside the computer.
  • Turn off AutoPlay to prevent malicious files from accessing your PC.
  • Disable File Sharing or make it password-protected when needed.
  • Switch off any remote services.
  • Disable FlashPlayer or use it with precaution.
  • Regularly update your system and software.
  • Carefully handle spam emails.
  • Turn off wireless services, like Bluetooth. Turn them on only when needed.
  • Employ automatic system protection via trusted AV software.
