What Type of Malware Is the Ryuk Ransomware Ransomware
Ransomware in general has been a growing trend with infection and particularly effective. Dharma ransomware prays primarily on those users who do not have a backup of their important files. The Ryuk Ransomware Ransomware encrypts your important documents, music, videos, pictures, archives and other data, making them no longer effective. The files cannot be opened after they have been attacked by the Ryuk Ransomware Ransomware and they have a custom extension added after their file name – a random A-Z 0-9 letters.
In fact, the infections with ransomware, just like Ryuk Ransomware have become so massive that you can be sure that at the moment somebody somewhere in the world is either opening a suspicious spammed e-mail attachment, believing it is legit or clicking on a malicious web link. The .TRON infection also has a ransom note, typical to most ransomware viruses and it’s called RyukReadMe.txt. It has the following contents:
All files on each host in the network have been encrypted with a strong algorithm.
Backups were either encrypted or deleted or backup disks were formatted.
Shadow copies also removed, so F8 or any other methods may damage encrypted data but not recover.
We exclusively have decryption software for your situation
No decryption software is available in the public.
DO NOT RESET OR SHUTDOWN – files may be damaged.
DO NOT RENAME OR MOVE the encrypted and readme files.
DO NOT DELETE readme files.
This may lead to the impossibility of recovery of the certain files.
