What is Djvut ransomware? And how does it carry out its attack?
Djvut ransomware is a crypto-malware designed to lock important data in a computer, leaving them inaccessible to victims. According to security experts, it appears to be a new variant of STOP ransomware. Nothing much has changed in this new variant except for the extension it uses to mark the files it encrypts which is .djvut.
Like pointed out, there are only a few changes in this new STOP ransomware variant. It still follows the same pattern in its attack. It starts to carry out its attack by dropping its malicious payload in the system. It is the one that connects the system to a remote Command and Control server. Djvut ransomware then downloads its other components from this remote server and places them on several system folders.
These malicious components are later on used for the data harvesting and stealth protection modules, both of which are used to collect data from the system and use them to bypass security programs installed. It also alters some registry keys and sub-keys in the Windows Registry so that it can execute its attack automatically in every system startup, making Djvut ransomware a persistent threat.
After it completes modifying the compromised system, Djvut ransomware will encrypt its targeted files using both the AES and RSA 1024 ciphers. Following data encryption, Djvut ransomware appends the .djvut extension to every affected file and releases its ransom note that’s either named “!readme.txt” or “_openme.txt”, which states:
“———————————————- ALL YOUR FILES ARE ENCRYPTED ——————————————
