WinSOS – Harnessing Trusted Binaries For Stealthy DLL Hijacking


WinSOS represents a sophisticated technique that turns the Windows operating system’s own features against it.

By manipulating executables in the WinSxS folder, a component trusted by Windows, attackers can discreetly execute malicious code.

This method, building on DLL Search Order Hijacking, does not require elevated privileges, making it a stealthy approach for infiltrating Windows 10 and 11 systems.

It stands out for its ability to bypass traditional defense mechanisms, leveraging the inherent trust in system binaries to conceal malicious activities.

This technique utilizes executables within the WinSxS folder, commonly trusted by Windows, to exploit the classic DLL Search Order Hijacking method.
