The latest variant appends the. 0000 extension to encrypted files and uses new contact emails, for example, a test file encrypted by this variant has an encrypted file name of 0D0A516824060636C21EC8BC280FEA12.0000.
The malware researcher Lawrence Abrams explained that this latest version of the ransomware uses the same encryption methods of previously discovered variants, but he noticed some slight differences.
The ransom note maintained the same file name _HELP_INSTRUCTION.TXT, but now uses the email@example.com, firstname.lastname@example.org, email@example.com, and firstname.lastname@example.org emails for a victim to contact for payment information.
This variant of the CryptoMix ransomware contains 11 public RSA-1024 encryption keys that will be used to encrypt the AES key used to encrypt the files on the victim’s PC.
As usual, let me suggest to backup your data and test the backup files to avoid ugly surprises.
Install a security software and maintain it and any other application up to date. It could be useful to install specific anti-ransomware solution that implements behavioral.
Colleagues have published an interesting article on ransomware protection titled “How to Protect and Harden a Computer against Ransomware.”
