https://github.com/v12-security/pocs/tree/main/fragnesia

Universal Linux local privilege escalation exploit. Fragnesia is a member of the Dirty Frag vulnerability class. This is a separate bug in the ESP/XFRM from dirtyfrag which has received its own patch. However, it is in the same surface and the mitigation is the same as for dirtyfrag.

It abuses a logic bug in the Linux XFRM ESP-in-TCP subsystem to achieve arbitrary byte writes into the kernel page cache of read-only files, without requiring any race condition.

https://github.com/L1v1ng0ffTh3L4N/EdgeSavedPasswordsDumper

This tool was created to show that whenever a user stores credentials in Edge (using the Microsoft Password Manager feature, e.g. Autofill), ALL credentials are stored in plaintext in the parent Edge process memory. This is obviously problematic in a shared environment (e.g. on a terminal servers) as an attacker can access all Edge processes for all logged on and disconnected users, and dump their saved credentials. Microsoft has said that this is "by design" and thus won't fix this.

https://github.com/0xMohammedHassan/morphkatz

Rewrites x86-64 machine code inside PE executables and raw shellcode into semantically identical but byte-different equivalents. Same arithmetic, same observable EFLAGS effects, same control-flow — different bytes. That breaks byte-pattern detection (YARA rules, Defender signatures, Elastic rules, Sigma detection content) without changing what the code actually does.

Tutorial: Adaptix C2 with ShellcodePack and MacroPack

Original post by Emeric

The article explains how to integrate the Adaptix C2 framework with BallisKit tools ShellcodePack and MacroPack to create stealthy payloads for red-team operations. Adaptix is an open-source command-and-control platform used for post-exploitation and adversarial emulation. The tutorial walks through setting up an Adaptix server on Linux and compiling the GUI client…

The article introduces COMouflage, a stealthy Windows process-injection technique that abuses the legitimate COM DLL Surrogate mechanism to execute malicious code inside trusted system processes. Instead of directly injecting into a target process, the attacker registers a fake COM object in the Windows registry under HKEY_CURRENT_USER, which does…

A recently disclosed vulnerability CVE-2026-0828 in the Windows kernel driver ProcessMonitorDriver.sys exposes a dangerous capability: any user-mode application that obtains a handle to the device can terminate arbitrary processes, including protected system processes, without proper access-control checks. This flaw effectively bypasses the normal Windows security model that protects critical system services and security components.…
