FXLocker Ransomware

FXLocker is a ransomware-type program designed to encrypt files on an infected computer and demand a ransom for decryption. This malicious software adds a “.fxlocker” extension to encrypted files and delivers a ransom note through a pop-up window and a text file named “README.txt”.

How FXLocker Ransomware Operates

Upon successful infiltration, FXLocker encrypts files using strong cryptographic algorithms and appends the “.fxlocker” extension to each encrypted file. It then creates a ransom note that instructs the victim on how to pay the ransom for file recovery.

The ransom note appears in a pop-up window and a text file named “README.txt”. Below is the full text of the FXLocker ransomware’s message:
