At first, after two months of lively distribution, the primary variations of ransomware have been defeated by means of the Romanian police, professionals from Bitdefender, and Europol. After revealing the flaw within the ransomware code, government hacked cybercriminals and Bitdefender created a unfastened GandCrab decryptor which is to be had on NoMoreRansom venture.[3]

Alternatively, it kind of feels that virus builders don’t seem to be more likely to surrender. Right through the primary months of 2021, they offered a number of new variations which might be tough the 2000 USD ransom in Sprint or Bitcoin in trade for the decryption key. The enhanced variations Gandcrab 5.0.4 and GandCrab 5.1 have not been decrypted as a result of hackers patched the essential flaw inside of 24 hours after the Bitdefender decryptor used to be launched.

At the present time, the virus is appending .[random characters] dossier extension. Moreover, the sufferer is given a Tor deal with to shop for the so-called Gandcrab Decryptor from virus creators. Alternatively, you will have to watch out when coping with hackers as a result of creating a cost does now not ensure that you’re going to get a key that you want.
