Digging Deeper into Vulnerable Windows Services

This blog post explains two Windows local privilege escalation techniques against insecure services: (1) reconfiguring a privileged service to run a compiled C# payload via InstallUtil to bypass application whitelisting and obtain SYSTEM-level execution, and (2) placing blank DLLs matching System32 DLL names into a service directory to crash the service when restarted, enabling overwrite or reconfiguration of the service binary. The post includes compilation and sc config examples and discusses limitations and mitigation considerations.
