The following section of the post will give you all the information related to this newly discovered CAT ransomware.

CAT Ransomware: Everything You Need to Know

CAT is the name of a ransomware-type malicious program that encrypts all the documents/files found on the victim’s computer and demands ransom payment (typically, cryptocurrency) for the decryption tools.

Instead of directly encrypting files, it renames the affected files with the following pattern: original filename, email address of CAT developers, victim’s unique ID, and “.Cat” as the file extension. For instance, a file originally named “1.mp3” would appear as “1.mp3.[whilingo@gmail.com][******].Cat” after the encryption process.

After that, it drops an “info.txt” text file (ransom note) into every compromised folder on the victim’s computer. This file contains detailed instructions on how to contact the developers of CAT ransomware and other details related to the encryption.

The ransom-demanding message informs victims that their data has been encrypted with strong cryptography algorithms. In order to recover or regain access to the encrypted data, users are told to buy the decryption keys/software. The ransom note is concluded with the email address (whilingo@gmail.com) to establish contact with the developers of this type of ransomware.
