What is Grovat ransomware? And how does it execute its attack?

Grovat ransomware is yet another variant of Djvu ransomware. This time, this new Djvu ransomware variant uses the “.grovat” extension in the files it encrypts. This Djvu variant uses a “.grovat” extension in marking its encrypted files, hence the name Grovat ransomware. Like its predecessors, it still executes its attack in the same pattern. Aside from its extension, and email address, there is no other noticeable change in this malware strain.

Once Grovat ransomware executes its attack on a targeted machine, it starts by employing a data gathering component in order to obtain information about the infected computer and its user. The harvested data is then used for stealth protection so that no programs installed in the computer will be able to detect it. After employing stealth protection, it modifies some entries in the Windows Registry to achieve a persistent attack.

After finding its targeted files, Grovat ransomware will start the encryption process using a sophisticated cipher. Following data encryption, it appends the .grovat extension to mark the files it has managed to encrypt. It then drops a text file named “_readme.txt” with a message that states:

“ATTENTION!
