What is RYK ransomware? And how does it implement its attack?

RYK ransomware is a data-encrypting malware designed to make files inaccessible to users. It is a new variant of Ryuk ransomware. It uses the .RYK extension in marking the files it encrypts, hence the name RYK ransomware. The instant its malicious payload is loaded in the system, it starts to implement a series of modifications. It starts by connecting the targeted system to a remote C&C server controlled by the attackers. From this remote server, RYK ransomware downloads its other components and puts them on several system folders in order to repress or launch system processes which allows it to implement its attack effectively.

RYK ransomware also makes alterations in some of the registry keys and sub-keys like Run and RunOnce. This allows the crypto-virus to execute its attack automatically every time a victim starts the computer. It also scans the system for security and antivirus programs that might interfere with its attack and disables or removes them. It then scans the computer for files with the following extensions:

.doc, .docx, .jpg, .jpeg, .xls, .xlsx, .pdf

Once it finds its targeted files, RYK ransomware encrypts them using a sophisticated encryption algorithm. Following file encryption, it appends the .RYK suffix to every compromised file and releases a file named “RyukReadMe.txt” which contains the following content:

“Your network has been penetrated.

All files on each host in the network have been encrypted with a strong algorithm.

Backups were either encrypted

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.

More than a year ago, world experts recognized the impossibility of deciphering by any means except the original decoder.

No decryption software is available in the public.

Antiviruse companies, researchers, IT specialists, and no other persons cant help you encrypt the data.

DO NOT RESET OR SHUTDOWN – files may be damaged.

DO NOT DELETE readme files.

To confirm our honest intentions.Send 2 different random files and you will get it decrypted.

It can be from different computers on your network to be sure that one key decrypts everything.
