Astral_Projection

Astral Projection - UDRL Astral Projection is a Cobalt Strike UDRL User-Defined Reflective Loader, that performs advanced module stomping. The UDRL loads a module using LoadLibraryExW, then manipulates its internals by setting VEH to intercept strategic calls that allow it to steal the section...

Advanced-Loader-Reverse-Engineering

From Shellhost to 3 DLLs: Analyzing an Advanced Loader with Payload Injection, CFG Bypass, and Downgrade Attacks Overview This analysis covers a sophisticated multi-phase loader targeting Shellhost.exe, amsi.dll, mstscax.dll, and clbcatq.dll. The loader uses module stomping, CFG bypass, COM...

Hunt-Sleeping-Beacons

Hunt-Sleeping-Beacons This project is mostly a callstack scanner which tries to identify IOCs indicating an unpacked or injected C2 agent. All checks are based on the observation that C2 agents wait between their callbacks causing the beacons thread to idle and this tool aims to analyze what...

FunctionStomping

FunctionStomping Description This is a brand-new technique for shellcode injection to evade AVs and EDRs. This technique is inspired by Module Stomping and has some similarities. As to this date 23-01-2022 alsohollows-hunter doesn't find it. The biggest advantage of this technique is that it isn'...

Hunt-Sleeping-Beacons - Aims To Identify Sleeping Beacons

The idea of this project is to identify beacons which are unpacked at runtime or running in the context of another process. To do so, I make use of the observation that beacons tend to call Sleep between their callbacks. A call to sleep sets the state of the thread to DelayExecution which is take...
