Blue Locker Ransomware – How Did It Infect My PC and What Happened?
Blue Locker also known as Blue Cryptor is a ransomware infection that might be delivered on computer systems in the background of all other running processes.
Malicious email attachments, fake notifications for software updates, freeware installers, torrent files and others may drop the payload file that triggers the malicious ransomware attack.
The activation of this file leads to the activation of a lot more malicious files which compromise basic security settings. Other essential system settings get compromised as well.
The idea behind the Blue Locker complex ransomware attack is money extortion. That’s why the threat implements changes to bypass active security measures and then encrypts valuable personal files.
Files encoded by this ransomware remain inaccessible until they are decrypted by a special tool that reverts their code back to normal. Files encrypted by the Blue Locker virus can be recognized by the malicious extension .blue appended to their original names. The encryption process which is dealt with the help of two cypher algorithms – AES and RSA, prevents victims from using files marked with the .blue extension.
A ransom demanding note (restore_file.txt) appears on the screen then. It informs victims about hackers’ demands. Below is shown a copy of the text message it stores:
