What is Gefest 3.0 ransomware? And how does it carry out its attack?
Gefest 3.0 ransomware is a new crypto-virus created to extort money from users by encrypting their important data. It is also the latest variant of the infamous Scarab ransomware. This new Scarab variant adds the .GEFEST extension to each file it encrypts. According to security experts, based on this crypto-virus’ ransom note, it appears that the cyber criminals behind Sigrun ransomware are also the ones that developed Gefest 3.0 ransomware.
Once Gefest 3.0 ransomware infiltrates a computer, it delivers a Trojan module and runs it. This module is the one that establishes an “always-on” connection with a remote server controlled by the attackers. This remote server is used by perpetrators to take over control of the affected host. After connecting the computer to this remote server, Gefest 3.0 ransomware downloads its other components from this server and sets them into several system folders. These other components are used for information gathering and to override security services or programs. Gefest 3.0 ransomware collects information from the infected computer and use them to prevent security services from interrupting its nasty attack in the system. In addition, this crypto-virus also modifies the Windows Registry which can render the machine completely unusable and behave in strange ways. Once it’s done modifying the system, Gefest 3.0 ransomware begins the encryption using the AES cipher. After the encryption, it appends the .GEFEST extension to all encrypted files and opens a text file named “HOW TO RECOVER ENCRYPTED FILES.txt” that states:
