What is an .REMK file?

.REMK is STOP Ransomware variant

File extension remk is used by one of the variants of STOP ransomware that appeared during the COVID-19 crisis (March 2020) and affected several hospitals. Pretty much like any other ransomware it encrypts users files, renames the file extension and demands ransom in bitcoins.

You can find decrypters for previous versions of STOP ransomware, so it's just matter of time before decrypter for this variant is available as well.

How to open:

When dealing with encrypted files caused by some ransomware, you basically have three choices:1. restore from backup2. wait for some researcher or AV company to release decryptor for your particular ransomware version3. pay the ransomHowever, even paying the ransom does not guarantee you that you will get your files back, as lots of ransomware are just pure scams.

How to convert:

You cannot convert these files to anything else. You first have to recover / decrypt the files before you can convert them to anything else.
