Gehad Virus Removal Guide (+Decrypt .gehad files) – DJVU Ransomware

Gehad – Ransomware

The Gehad stands for a ransomware-type infection. Initially, it was revealed by Michael Gillespie. The virus comes from the DJVU ransomware family. Gehad was elaborated particularly to encrypt all major file types. When the file is encrypted people are not able to use them. Gehad adds the “.gehad” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Gehad, will be renamed into “myphoto.jpg.gehad. As soon as the encryption is finished, Gehad places a special text file (such as “_readme.txt“) into every folder containing the encrypted data.

The message given by Gehad text file asking for the ransom is definitely the same as the statements given by other ransomware representatives coming from the DJVU type. It literally discusses that the information is encrypted and that the only way to bring back it is to use a an unique decryption key. Sadly, this is definitely true. The kind of cryptography mechanism applied by Gehad is still not correctly examined. Still, it is definitely particular that each victim might be given the specific decryption key, which is absolutely distinct. It is difficult to bring back the files without the key available.

“Don’t worry, you can return all your files!”, Gehad message:

Don't worry, you can return all your files! virus

Another trick of Gehad is that the victims cannot get to the key. The key is saved on a particular server run by the frauds connected with Gehad ransomware. To get the key and recover the important info people have to pay the ransom, which amounts to $980. To get the payment details users are instructed to contact the frauds through email or telegram. The alert likewise indicates that the users need to contact the Gehad developers within 72 hours after the encryption happened. The message says that doing so users will get a 50% discount, so the ransom quantity will fall to $490.

Nonetheless, regardless of the asked for quantity, people should keep away from paying the ransom virus. Cyber frauds are not fair, so they tend to totally disregard what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom generally does not give any positive result and people just lose their money for nothing.

We highly encourage that you do not contact these crooks and definitely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Gehad ransomware and to recover the data data for free. Hence, the only right decision is to recover the lost data from the available backup.
