Last week I discovered that all of my pictures, from 5 years back were encrypted and unaccessible.

Though I had kept an updated copy, on another drive (too bad I didnt switch off the power on one of them), their interesting virus took both of the drives down completely.


This is not exceedingly funny, but as I investigate on forums, it looks like these files are lost since the designers of the algorithms of the virus, made it so hard, so they cant decrypt it themselves even.


Does anyone have some light in the darkness about this?

"Some" say that by now only v1 and v2 of CryptXXX ransomware virus is decryptable (for free), v3 don't (only partial recovery).

Anyway, I can say that is not true because I got some files encrypted with v2 (exactly v 2.006) and they ARE NOT decryptable.


So, from v 2.006 and over it's not possibile, for now and for free to decrypt them.

Kaspersky Lab's RannohDecryptor tool will work for those infected with older variants of CryptXXX.Kaspersky's tool will not work on CryptXXX 3.x variants...it will detect but not decrypt...see CryptXXX updated to version 3.0, Decryptors no longer Work.

Trend Micro released a Ransomware File Decryptor for victims of CryptXXX v1/v2/v3* but warns that it's decrypter may only do a partial decryption on CryptXXX 3.0 encoded files.

Dr.Web has advised Files compromised by CryptXXX before June 2016 can now be decrypted by Doctor Web.
Updated policy from Dr.Web (11/25/15): Free file decryption assistance only for PCs protected by Dr.Web at the moment of infectionBefore attempting decryption, it is recommended to back up the original encrypted files first and perform a test decryption on sample copies of the encrypted files first in case something goes awry.

There is an ongoing discussion in this topic where you can ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.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...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. Doing that will also ensure you receive proper assistance from our crypto malware experts since they may not see this thread. To avoid unnecessary confusion, this topic is closed.
