CryptoLocker3 Ransomware Description

Security experts have uncovered a new virus threat which is known as the CryptoLocker3 Ransomware made by the computer developer staffttt. The malware poses as a strain of the CryptoLocker family however it is unrelated to them.

Like other similar viruses it follows the typical ransomware infection pattern – encrypts target user data, displays a ransomware note and extorts the victim for the payment.

CryptoLocker3 ransomware includes an encryption module that targets specific user files and encrypts them with the AES cipher. The compromised files receive the .cryptolocker extension. The following types of extensions are the main targets:

The ransomware developer has crafted two versions of the ransomware note which is used to extort the computer victims alongside with a screen locker function which blocks the user’s screen and prohibits any other activity. The first version displays the following message:
