Windows Dll Execution Techniques

Keypoints

• LOLBins such as msiexec, rundll32, regsvr32, netsh, control.exe, register-cimprovider, and mavinject can load and execute a DLL reverse shell.
• msfvenom is used to build a 64-bit Windows reverse-TCP DLL payload (shell.dll) for delivery.
• A listener (rlwrap nc -lvnp 1234) must be active on the attacker host to receive the reverse shell.
• Detect suspicious behavior by alerting on outbound connections from trusted Windows binaries and DLL loads from user-writable paths.
• Mitigations include AppLocker/WDAC, Defender ASR rules, command-line auditing, network egress filtering, and limiting SeDebugPrivilege.
