Question

Malware

Hello. One computer was attacked by the Hidra ransomware. All files have the Hidra extension. And they can't be opened. How to remove a virus and recover files? There are no backups

Answer 1

No way. If there are contacts of the extortionist - pay (yes, the easiest way is to pay!), otherwise try to contact Kaspersky or another antivirus program - maybe they have a key or another decryption method. This method is absolutely WITHOUT guarantees.

Answer 3

Well, if a virus securely encrypted all files with a certain key, and then sent this key to the author of the virus, then nothing . Is that to succumb to blackmail and pay.

Answer 4

If only the extensions are changed, then this is not a problem.
But if a cryptographer with jokes from a trolltech, then my advice to you is to leave this matter.
