What is YobaCrypt ransomware? And how does it implement its attack?

YobaCrypt ransomware is one of the latest ransomware threats discovered lately. This new file-encrypting virus is also known as “Ferrlock ransomware” and it uses the AES encryption algorithm in locking files in a computer and appends a “.yoba” extension to every file it encrypts.

Once it compromises a targeted machine, it will implement a series of modifications by starting to initiate a connection to a remote Command and Control server where it downloads its other components. After the malicious components are downloaded, it places them on various system folders with the aim of launching or repressing system processes. After controlling system processes, it uses an information gathering module which obtains data from the computer. The data obtained is processed to create a unique ID for the compromised computer and is then used for the stealth protection module. This module is the one that bypasses any security programs installed in the system. This crypto-virus also has the ability to obtain administrator permissions, language and regional settings, read and write permissions, obtain system and network information as well as steal files.

After all the system modification, YobaCrypt ransomware will start the encryption process using the AES cipher. Following file encryption, it adds the “.yoba” extension to each one of the compromised files and opens the “.!=How_recovery_files=!.txt” file that contains the following ransom note:
