What is Jaffe ransomware? And how does it implement its attack?
Jaffe ransomware is a data-encrypting virus discovered recently. It is designed to lock important files in a computer and extort money from victims. It uses a custom extension, “.[[email protected]]” in marking the files it encrypts. Jaffe ransomware is a typical ransomware threat that has the same sequence of attack as other ransomware threats.
Once it infects a computer, it launches a payload file used to connect the computer to a remote C&C server controlled by the attackers. From this server, it downloads its other components and places them on several system folders. This allows the crypto-virus to manipulate the system processes. After downloading its malicious components, Jaffe ransomware employs a data gathering module that collects data in the system. The collected data is then sent to the remote server and is used for the stealth protection module. This second module is the one that scans the computer for strings of antivirus programs, sandbox environments, and security programs that could interfere with its attack. Once it finds them, it either removes or disables them.
Moreover, Jaffe ransomware proceeds to modify some entries in the Windows Registry, allowing it to automatically run in every system boot which makes it a persistent threat. After system modification, it will begin encrypting its targeted files using a sophisticated encryption algorithm. It appends the “.[[email protected]]” extension to every encrypted file and changes the desktop wallpaper of the computer that points to its ransom note named “READ THIS.txt” which contains the following content:
