The article explains how attackers exploit a vulnerable signed driver (BYOVD) to obtain a kernel read/write primitive. It shows how unsafe IOCTL handlers allow manipulating kernel memory and abusing driver functionality for offensive operations.
Malware and cryptography 44 – encrypt/decrypt payload via Discrete Fourier Transform. Simple C example.
Demonstration how malware can encrypt and decrypt payloads using the Discrete Fourier Transform (DFT). It provides a simple C example showing how mathematical transforms can hide shellcode and help evade static signature-based detection.
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.
Analysis of Improper Authorization in Windows Error Reporting CVE-2026-20817 (PoC)
Proof-of-Concept (PoC) for CVE-2026-20817, a local privilege escalation vulnerability in the Windows Error Reporting (WER) service. The vulnerability allows an authenticated low-privileged user to execute arbitrary code with SYSTEM privileges by sending specially crafted ALPC messages to the WER service.
Writing Optimized Windows Shellcode (old but gold)
A deep dive into crafting ultra-compact Windows shellcode that walks the PEB, resolves APIs via export hashing, and runs fully self-contained without imports — showing how C can build stealthy, position-independent payloads.
PPLControlShells — Protected Process / PPL Control shells Tool
PPLControlShells (the ppexec console tool) is a native Windows PP/PPL experimentation and control utility (x64)designed to help researchers understand, test, and demonstrate how Protected Process (PP) and Protected Process Light (PPL) behave on modern Windows (10/11 + compatible Server builds).
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).
Securely Embedding WASM Plugins in Your Project
