I have some old files, encrypted by CryptXXX v1 ransomware about 2 years ago. RannohDecryptor by Kaspersky and Trend Micro Decryptor both ID the ransomwared files as CryptXXX v1 encryption, but neither are able to decrypt them. They ask for the original and decrypted files for comparison, of which I have a couple copies, but the ransomwared files are always couple kbs different the original files so the decryption programs don't accept them.
Does anyone have any ideas or tools I can use to decrypt Crypt XXX V1 files that can't be decrypted by Trend Micro's or Kaspersky's tools? Thank you.
