A hands-on guide to building a basic Windows EDR with a kernel driver, callbacks, static analysis, DLL injection, and hooks to detect remote shellcode injection.
From MessageBox to Rootkit: A Practical Journey Through Windows Malware Internals
The article walks through Windows malware development from dynamic API resolution and PEB walking to injection, APC execution, driver basics, DKOM process hiding, and kernel callback abuse.
COMouflage: Stealthy DLL Surrogate Injection for Process Tree Evasion
COMouflage is a stealthy Windows injection technique that abuses COM DLL Surrogates to execute malicious DLLs inside dllhost.exe, making svchost.exe appear as the parent process and hiding the attacker’s process from detection.
Stealth Injection with ROP: Thread Hijacking Without Executable Memory
The article presents T(ROP)H, a process injection technique that hijacks threads and uses a ROP chain to load a DLL without allocating executable memory, reducing common detection indicators used by EDR systems.
Crimes against NTDLL – Implementing Early Cascade Injection
How to implement Early Cascade Injection in Rust, a stealthy Windows process injection technique that hijacks shim engine callbacks in ntdll to execute shellcode during early process initialization, before many EDR hooks activate.
RPC Proxy Injection Part II: Breaking Elastic EDR Telemetry
The article explains enhancing RPC Proxy Injection to evade Elastic EDR telemetry by avoiding common API calls like WriteProcessMemory and CreateRemoteThread, using custom shellcode delivery via thread descriptions and APCs to hide malicious behavior.
Living off the Process
The article “Living off the Process” details a technique to inject and execute shellcode into a remote Windows process by reusing existing RWX memory, ROP gadgets, and threads within that process, avoiding conventional memory allocation and lowering detection footprint.
EarlyBird APC Injection: A Deep Technical Analysis
The EarlyBird APC technique creates a trusted process in a suspended state, allocates memory for shellcode, and writes the payload. It then queues the shellcode as an Asynchronous Procedure Call (APC) to the suspended thread. Resuming the thread forces immediate, stealthy execution of the malicious code.
Process Injection via Component Object Model (COM) IRundown::DoCallback() for run cmd.exe from lsass.exe or other pids
A PoC/demo demonstrating code injection via COM (using the IRundown::DoCallback() mechanism) to execute a payload in the context of a selected process, including lsass.exe (or any other PID).
