What is Sodinokibi ransomware? And how does it execute its attack?
Sodinokibi ransomware is a data-encrypting malware that demands ransomware from its victims to recover compromised data in an infected computer. The ransom amount may differ from $2000 to $5000 depending on how fast a user can pay up. Its encrypted files can be identified by the random characters that are added on their file names. Like other typical ransomware threats, it follows the same pattern when executing its attack.
As soon as the attackers exploits “CVE-2019-2725”, Sodinokibi ransomware will be installed in the system and will implement a series of modifications starting by connecting the computer to a Command and Control server. This server is managed by the attackers and is where the other components will be downloaded. Once these malicious components are downloaded, they will be placed into system folders. They are then used to execute the data harvesting module which collects information from the system. The information obtained will be used in the second module called stealth protection. This second module is used to scan the system for strings of antivirus programs, sandbox environment and security programs.
Additionally, Sodinokibi ransomware also alters the Windows Registry, allowing it to execute its attack automatically every time you turn on your computer. After it achieves persistence, Sodinokibi ransomware will start the encryption with the targeted files. It mostly targets user-generated files like videos, images, documents, database, audio files, and many more. After the encryption, it adds random characters as its extension to all encrypted files. It then drops its ransom note named “file-marker-HOW-TO-DECRYPT.txt” that reads:
“Hello dear friend!
Your files are encrypted, and, as result you can’t use it. You must visit our page to get instructions about decryption process.
All encrypted files have got * extension.
