Rewterz Threat Alert – Diving Into Sodinokibi Ransomware

October 16, 2019

Severity

High

Analysis Summary

McAfee’s Advanced Threat Research (ATR) team took a deep dive into the code for the Sodinokibi (aka REvil) ransomware-as-a-service and published their results in an article. The ATR team ran across Sodinokibi at the end of April, which was about the same time that it was announced that GandCrab would be shut down. Sodinokibi initially used a vulnerability in Oracle’s WebLogic server to infect a victim. This malware is offered as a service with a group of people developing the code. Their affiliates, those that pay for the service, can then spread Sodinokibi as they desire, whether through phishing campaigns, exploit kits, brute force RDP attacks, or uploading tools and scripts that elevate privileges and then execute the malware. The ATR team compared the unpacked Sodinokibi code with version 5.03 of GandCrab to determine similarities and found that it was in the functions that the two were most alike. The ATR team alluded that one or more developers for Sodinokibi may have had access to the GandCrab source code.

Vulnerability Exploited

CVE-2018-8453

Microsoft Windows could allow a local authenticated attacker to gain elevated privileges on the system, caused by improper handling of objects in memory by the Win32k component. By executing a specially-crafted program, an authenticated attacker could exploit this vulnerability to execute arbitrary code in kernel mode.
