  • Chinese program Sunlogin Remote Control is actively used by hackers to carry out BYOVD attacks

    A new hacking campaign exploits vulnerabilities in Sunlogin's remote access program to deploy Sliver's post-exploitation toolkit and launch BYOVD attacks to disable antivirus products.

    Sliver is a post-exploitation toolkit created by BishopFox that attackers started using as an alternative to Cobalt Strike last summer. They use it for network surveillance, executing commands, loading DLLs, creating sessions, manipulating processes, and so on.

    According to a report by AhnLab's Security Emergency Response Center (ASEC), the newly identified attacks targeted two vulnerabilities discovered last year in Sunlogin's remote access software.

    Attackers use these vulnerabilities to compromise a device and then execute PowerShell scripts to launch reverse shells or install other payloads such as Sliver, Gh0st RAT, or XMRig Monero.

    The attack begins by exploiting the CNVD-2022-10270 / CNVD-2022-03672 vulnerabilities that are relevant in Sunlogin version 11.0.0.33 and earlier. Attackers use vulnerabilities to execute an obfuscated PowerShell script and disable antivirus systems before deploying backdoors.

    The script decodes the portable .NET executable and loads it into memory. This executable is a modified version of the Mhyrot2DrvControl open source tool, which is designed to take advantage of vulnerable Windows drivers.

    Mhyprot2DrvControl runs mhyrot2.sys, a digitally signed anti-cheat driver for the Chinese game Genshin Impact. This driver, according to Trend Micro, has been used for ransomware attacks since last year.

    “The developer of Mhyprot2DrvControl has provided many functions that can be used with elevated mhyrot2.sys privileges. Among them, for example, a feature that allows hackers to forcibly terminate anti-virus program processes, which is very useful for developing malware,” ASEC experts explain in their report.

    The second part of the PowerShell script downloads Powercat from an external source and uses it to launch a reverse shell that connects to the C2 server, giving the attacker remote access to the compromised device.

    In some cases, the attacks were followed by the installation of the Sliver implant ("acl.exe"). The attackers also installed Gh0st RAT for remote file management, key registration, remote command execution, and the ability to exfiltrate data.

    Microsoft recommends that Windows administrators enable a Vulnerable Driver Block List to protect against BYOVD attacks.
