Ransom Note & Ransom Amount for Budak Ransomware

Cyber-criminals behind Stop Budak Ransomware seek to generate illicit revenue by extorting hefty amount from the victims in return of a decryption key. The cryptography algorithms used by the hackers to encrypt the files also generate a unique decryption key for each infected system.

Once the files are encrypted, a ransom-demanding message in text format (_readme.txt) is dropped in every folder of the infected systems that contains .budak files.

The note appears every-time the user tries to open the encrypted files. It prompts the user to contact the hackers & pay the ransom amount (in Bitcoins) in order to restore the data.

The hackers offer to decrypt one encrypted file (not containing sensitive information) for absolutely no cost. The restored file is then sent back to the victim as a proof of decryption.

Impacted users may contact the hackers via e-mail on varasto@firemail.cc or gorentos@bitmessage.ch.

Ransom Amount: The Ransom amount demanded by STOP DJVU Ransomware hackers remains same for all the variants.

The hackers demand $980 for every decryption key & ask users to contact them to receive payment & decryption related instructions.

Any victim that contacts the hackers within 72 hours of the encryption can avail 50% discount on the Ransom amount (i.e., $480).

Note: The claim to decrypt the files for absolutely no cost is a mere trick to take the users into thinking that decryption is possible.

Many of the victims often tend to contact the hackers & pay them the ransom amount as they fear losing their data. However, the analysis by cyber-security researchers show that hackers avoid responding the victims after the amount has been received.

Therefore, we advise you to avoid contacting the hackers, if infected. Do not let hackers extort money & succeed in their plans.

Rather, be vigilant & act smart. Take a backup on your data regularly on an external storage device & be cautious wile streaming online. Following good security practices may help in preventing .Budak File Virus from infecting your system.
