🔧 Temporary Workarounds
Restrict DLL search paths
windowsConfigure Windows to restrict DLL search paths using SafeDllSearchMode and CWDIllegalInDllSearch registry settings.
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager" /v SafeDllSearchMode /t REG_DWORD /d 1 /f
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager" /v CWDIllegalInDllSearch /t REG_DWORD /d 1 /f
Application whitelisting
windowsImplement application control policies to prevent unauthorized DLL loading.
🧯 If You Can't Patch
- Implement strict file system permissions to prevent unauthorized DLL placement in application directories.
- Monitor for suspicious DLL loading behavior using endpoint detection tools.
