SCR ransomware – a Matrix family virus which uses AES-128 and RSA-2048 cryptography to encrypt files

SCR ransomware

SCR ransomware is a hazardous file locking Windows virus which is related to the Matrix category. These cyber threats are known for their difficult operating, stealth spreading techniques, and secret encryption process which is performed by using strong AES-128 and RSA-2048 cryptography. SCR virus adds the .SCR appendix to each locked file and folder. After that, the crooks display a !README_SCR!.rtf informative message which urges to pay a particular ransom price or encrypted data will be deleted permanently after a time duration of seven days. Additionally, the hackers urge users to contact them via all three email addresses in case a misunderstanding happens and the message does not reach the recipient. Continuously, victims are offered to send three files which together contain no more space than 5 MB in order for the crooks to demonstrate that they are truly capable of decrypting the data.

SCR ransomware is a type of malware which can perform different activities all over the system. It can run rogue processes in the Windows Task Manager, create malicious entries and inject them into the Windows Registry[1] section. Moreover, the ransomware might carry other harmful cyber threats or infected executables and leave them in the system also.

To continue, SCR ransomware might be capable of deleting Shadow Volume Copies[2] of encrypted data. The cyber threat launches a specific command to perform such a process. Crooks release the ransomware with such additional feature as eliminating Shadow Copies will not allow decrypting files by using tools which require untouched Shadow Volume Copies.

We recommend performing the SCR ransomware removal with reputable computer security software. Moreover, you need to detect all additional malicious content that might be hidden all over the Windows operating system. We offer to try a tool such as Reimage as by terminating the cyber threat on your own, you might cause more damage to your computer system.
