AI-suggested
1. Immediately audit and remove any user-writable directories from the system PATH environment variable to prevent malicious DLL placement. 2. Restrict write permissions on directories included in the PATH to trusted administrators only. 3. Implement application whitelisting and DLL integrity verification to detect and block unauthorized DLLs. 4. Monitor file system changes in PATH directories for suspicious activity using endpoint detection and response (EDR) tools. 5. Educate users about the risks of executing untrusted applications and the importance of avoiding unnecessary user interaction that could trigger exploitation. 6. Isolate systems running Sunshine for Windows in segmented network zones to limit lateral movement if compromised. 7. Engage with LizardByte for patches or updates addressing this vulnerability and plan prompt deployment once available. 8. Employ least privilege principles to minimize the impact of potential exploitation. 9. Regularly review and update security policies regarding environment variable management and software installation practices.
