Reports have increased recently, regarding a new ransomware virus, called BitCrypt. I may use unique RSA-100 type of encryption that is next to impossible to decrypt. Like other ransomware viruses, such as CryptoWall, Troldesh, CryptPKO and others, BitCrypt scans for the files on the affected PC, then encrypts them with a custom .bitcrypt(filename.docx.bitcrypt) extension. This behavior is very similar to another ransomware virus, using .crypt extension on the files it encrypts.
What Does BitCrypt Ransomware Do?
Once on your computer, a malicious file may infect it with .bitcrypt ransomware. This may happen if the user opens an infected document sent from another email, disguised as a familiar one to them, saying “Important”. Another strategy may be the employing any social engineering technique that may trick the user into opening malicious content. Also, users can get infected by having PUPs on their computers that sometimes cause malicious redirects.
Once on the computer, BitCrypt may begin to scan for files to encrypt. After it finds its targets, it encrypts them, creating a bitcrypt.ccw file in %AppData% directory for Windows with the current content:
This content that has upper case, lower case letters and numbers plus signs in it is the encryption itself. To it, a unique encryption key may correspond. Such encryption keys are held on the cyber criminals’ servers along with other information. Some users report seeing the following message after their files have been encrypted with the .bitcrypt extension:
