What to do
AI-suggested
1. Remove or uninstall the Genshin Impact game and associated mhyprot2.sys driver from any corporate or sensitive systems where it is not essential. 2. Restrict installation of unauthorized software, including games, on corporate endpoints to prevent the vulnerable driver from being installed. 3. Monitor systems for the presence of the mhyprot2.sys driver and audit its usage. 4. Apply the principle of least privilege to user accounts to reduce the risk of local exploitation. 5. Use endpoint detection and response (EDR) tools to detect suspicious local privilege escalation attempts. 6. Educate users about the risks of installing unauthorized software on corporate devices. 7. Follow HoYoVerse's official channels for any patches or updates addressing this vulnerability and apply them promptly once available. 8. Implement application whitelisting to prevent execution of unauthorized drivers or kernel modules. 9. For environments where gaming is permitted, consider isolating gaming systems from critical networks to limit potential lateral movement.
Description
The HoYoVerse (formerly miHoYo) Genshin Impact mhyprot2.sys 1.0.0.0 anti-cheat driver does not adequately restrict unprivileged function calls, allowing local, unprivileged users to execute arbitrary code with SYSTEM privileges on Microsoft Windows systems. The mhyprot2.sys driver must first be installed by a user with administrative privileges.
