logon.bat – A batch file that executes HelpPane.exe, kills antivirus and other services, and executes svchost.exe.

This Windows installer contains avg.exe, a malicious file masquerading as AVG Internet Security, and is responsible for dropping and executing the following: A list of the techniques used in this operation can be found in the MITRE ATT&CK analysis at the end of this article.Īnother malicious file, avg.msi, was transferred to the netlogon share \\\NETLOGON\avg.msi. Meanwhile, the timeline and attack sequence of the threat actor’s activities that we present here are noteworthy for security teams. All these factors mean that the usage of this driver is likely higher than those of previously discovered rootkits (such as the ones mentioned in the preceding section). Organizations and security teams should be careful because of several factors: the ease of obtaining the mhyprot2.sys module, the versatility of the driver in terms of bypassing privileges, and the existence of well-made proofs of concept (PoCs).

Since mhyprot2.sys can be integrated into any malware, we are continuing investigations to determine the scope of the driver. The threat actor aimed to deploy ransomware within the victim’s device and then spread the infection.

This ransomware was simply the first instance of malicious activity we noted. Genshin Impact does not need to be installed on a victim’s device for this to work the use of this driver is independent of the game. As a result, commands from kernel mode killed the endpoint protection processes.Īs of this writing, the code signing for mhyprot2.sys is still valid. Analyzing the sequence, we found that a code-signed driver called “ mhyprot2.sys”, which provides the anti-cheat functions for Genshin Impact as a device driver, was being abused to bypass privileges. Security teams and defenders should note that mhyprot2.sys can be integrated into any malware.ĭuring the last week of July 2022, a ransomware infection was triggered in a user environment that had endpoint protection properly configured. The driver is currently being abused by a ransomware actor to kill antivirus processes and services for mass-deploying ransomware. Such is the case of mhyprot2.sys, a vulnerable anti-cheat driver for the popular role-playing game Genshin Impact. However, when a legitimate driver is used as a rootkit, that’s a different story. These rootkits are usually signed with stolen certificates or are falsely validated. There have already been reports on code-signed rootkits like Netfilter, FiveSys, and Fire Chili.
