What is Tabufa ransomware? And how does it carry out its attack?

Tabufa ransomware is a data-encrypting malware created to lock important files in an infected computer. This newly discovered crypto-malware belongs to the GlobeImposter 2.0 ransomware family which means that it contains similar code snippets from the infamous ransomware group so it is possible that the sample has been bought from the dark web or it could also be a customized version of a ransomware threat.

Tabufa Ransomware

Once it infects a computer, it drops its malicious payload and executes it. The malicious payload then connects the infected computer to a remote Command and Control server controlled by the attackers. From this remote server, Tabufa ransomware downloads other malicious components and places them in several system folders. After that, it modifies the Windows Registry in order to achieve persistence and to launch or repress processes in the Windows environment.

These registry entries are usually designed in a way to start the crypto-malware automatically on every system boot. Once all the modifications in the system are carried out, it then begins the encryption process using sophisticated cryptography. After the encryption is completed it appends the .tabufa extension in every encrypted file. Following data encryption, it releases an HTML file named “how_to_back_files.html” which contains the following ransom note:

“All your data has been ciphered!
The only way of recovering your files is to buy a unique decryptor.
