What is FilesLocker v2.0 ransomware? And how does it carry out its attack?
FilesLocker v2.0 ransomware is a file-encrypting malware that happens to be a new variant of FilesLocker ransomware which was first released on October 2018. And now it seems that its developers decided to modify the crypto-malware to create an improved variant, hence, FilesLocker v2.0 ransomware. It still uses the same encryption algorithm in locking files which is AES although the extension it now uses is a different one,”.[[email protected]]”.
Once it carries out its attack, FilesLocker v2.0 ransomware will drop its malicious payload in the system, “Installer.exe”, which obviously is disguised as an installer for some program. After this malicious payload is executed, FilesLocker v2.0 ransomware gets installed in the system. It then connects the infected computer to a remote Command and Control server where it downloads its other components and places them on system folders. These malicious components are used for the data gathering and stealth protection modules. In the first module, it collects data in the system which is used for the second module. The stealth protection module scans the computer for strings of security and antivirus programs installed in the system and when it finds them, the crypto-malware either disables them or removes them. After that, it creates modifications in the Windows Registry to allow it to run automatically on every system boot. Following these system changes, FilesLocker v2.0 ransomware will start the encryption using the AES cipher and appends the “.[[email protected]]” extension to the affected files. Once the encryption is completed, it opens a program window which contains the following ransom note:
All your important files are encrypted!
All your important files(database,documents,images,videos,music,etc.)have been encrypted!and only we can decrypt!
To decrypt your files,you need to buy the decryption key from us.We are the only one who can decrypt the file for you.
Trying to reinstall the system and decrypting the file with a third-party tool will result in file corruption,which means no one can decrypt your file.(including us),if you still try to decrypt the file yourself,you do so at your own risk!
As a proof,you can email us 3 files to decrypt,and we will send you the recovered files to prove that we can decrypt your files.
#How to decrypt?
