What is Battlefield ransomware? And how does it work?

Battlefield is a file-encrypting Trojan virus developed using the open source platform, HiddenTear. It utilizes the AES 256 encryption algorithm during its encryption attack and appends the .locked extension on the targeted files in your computer. After the encryption, it changes the wallpaper on your desktop with an image saying, “Oops! Your files have been encrypted!.” This tactic is also used by the notorious WannaCry ransomware after its attack.
It then drops its ransom note in the form of a text file, named READ_ME.txt wherein the cyber criminals tells you that your files are encrypted by the Battlefield ransomware and that it can only be restored using a specific decryption tool. Here’s the full context of the ransom note:
“Ooops! Your files have been encrypted.
Warning: Never change the file names and extensions and their location.
Send the transaction code and user name of the system and the date and time of the Ransomware to the following email.
You must send 50 USD to this address.
Decrypt your files after payment!
Buy Bitcoin with Credit Card and send to me: [xxx]
Address Mail:[email protected]
BTC Address: [xxx]”
Even though the crooks demand only a small amount of money, paying them won’t do you any good. Not only you’ll risk your confidential information when you pay these crooks but it won’t guarantee you the recovery of your files since most victims of this kind of infection are often given the cold shoulder by the cyber criminals after they received the payment.
During its infiltration, this ransomware installs a malicious program named Battlefield-Decrypter.exe which is supposed to decrypt the encrypted files once you pay the ransom. However, there is no certainty that this decryption tool works, so it’s basically useless. And besides you can remove and recover your files using the instructions we have provided below.
