Does anyone know how I can decrypt files that require Microsoft decryptor? My computer got attacked by RSA 4096 ransomware CryptXXX virus and everything in "My Documents" folder are encrypted but with original extensions.

Ransom note name : README.html, txt and one
TOR url : http://ccjlwb22w6c222p2k.to and city

Any help is greatly appreciated!

Trend Micro has a decrypter that MAY help you recover some of your files. You probably have variant 4 or 5.

 

Note this from TM: 

 

 

 

Edit: I noticed that someone in the CrypMIC topic mentioned getting a Microsoft Decrypter. Have you verified with ID-Ransomware exactly which ransomware you have?

 

Upload an encrypted file AND the ransom note here:https://id-ransomware.malwarehunterteam.com/

 

The site will attempt to give you a positive ID and guide you on what to do next.

Pretty sure its CrypMic. It ended up being the "mysterious CryptXXX" that didn't rename files and identified as "Microsoft Decrypter". Also, CrypMic uses README.html.

 

There is no way to decrypt files hit by CrypMic. You can only restore from backups basically.

Either way, uploading a ransom note and encrypted file to ID Ransomware as mentioned will be the best judge. It can detect the unique hex pattern that CrypMic leaves in files.

Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion. To avoid unnecessary confusion, this topic is closed.
