What to Do If Your Files Are Encrypted by .Djvut Ransomware
Dealing with ransomware attacks could be extremely stressful. The most important thing is to remember to never send any money to the creators of the malware. Instead, you should first clean your computer from any traces of the ransomware threat in order to stop it from encrypting any new files or spreading further through the network. The easiest way to do that is to install a legitimate anti-malware program and let it scan your entire computer system. Then, it's best to allow the anti-malware program to remove any malicious files detected by the scan.
As for the encrypted files, there are a couple of options to consider. If you have a backup created before the ransomware had invaded your computer, you could restore your data from it. In the case that a suitable backup is unavailable you could archive the entire drive and wait for a possible decryption tool to be created by the cybersecurity community. Fortunately for the victims of .Djvut Ransomware, there is such a decryptor that might help recover files.
Decryptor Is Available for .Djvut Ransomware Victims
Michael Gillespie, a ransomware specialist, has updated his STOP Decryptor to work with ".djvut" encrypted files. There are a couple of limitations, though. Currently, the decryptor works with only 2 offline keys - "6se9RaIxXF9m70zWmx7nL3bVRp691w4SNY8UCir0" and "D02NfEP94dKUO3faH1jwqqo5f9uqRw2Etn2lP3VB" (the keys used by the malware if it failed to get a key from its server), or if the user has been provided with a key. It is worth a shot to try and see if the decryptor will be able to restore your files to their original state.
