Infected with Ransomware

[anirbandutta01]

Today at my office a system infected with RYUK Ransomware, all files encrypted with (dot) ryk extension. Already scanned with OHTS, ESET & Malwarebytes & malicious things are removed but files are still encrypted. Is there any any to get back files? Is there any decryptor ?

ID Ransomware

Upload a ransom note and/or sample encrypted file to identify the ransomware that has encrypted your data.

Submit a sample of the compromised files for their review.
They will reply and let you know what you are dealing with.

From what we know now, your files are not recoverable.
Your only solution would be to restore the files from a good backup if you have one.

The compromised files can be transferred to a CD or Flash drive.
Should a solution be found in the future you may be able to restore them.

It's never to late to use common sense to guard against being infected.

Okay tomorrow I'll try this

If I able to transfer encrypted files to USB flash drive to other PCs is there any chance to spread Ransomware ? Can I recover files by any software If I transfer it to another PC ?

Hi,

The crypted files are safe. They will not infect other files in you flash drive.

Can I recover files by any software If I transfer it to another PC ?

No.

No.

So is there any decryptor to decryptor files ?

 

[nasdaq]

Hi,

As as as I know not there is no decryptor. May never get one.

Did you submit a sample of the compromised files as suggested?
