Skitter Creek Bath Salts
Unlocking _everything_ on the CPU with DRAM scrambling
Skitter Creek Bath Salts is a security research project exploring how low-level DRAM address translation affects processor security boundaries. It demonstrates that changing memory-controller translation behavior can expose physical memory regions normally hidden from the operating system. The research targets AMD Family 16h processors, whose documentation describes relevant DRAM translation registers. Its examples examine protected areas associated with the Platform Security Processor,... -

LibSecRm - Secure Removal Library
A library for secure deleting data on-the-fly
LibSecRm (LIBrary for SECure ReMoval) is a set of replacements for these standard C functions which cause data removing from files. The data is first securely wiped on-the-fly, to protect the user's privacy, then the original functions are called. There is NO NEED to rebuild your software, because LibSecRm is a pre-loadable library, meaning you just need to RUN the software with LibSecRm loaded. LibSecRm is also a development library. The following wiping methods are supported:... -

sRDI
Shellcode implementation of Reflective DLL Injection
sRDI is a compact project that implements a shellcode form of Reflective DLL Injection, enabling DLLs to be converted into position-independent shellcode and loaded in memory by a small in-process PE loader. The codebase groups a C implementation of a reflective PE loader with multiple loader/wrapper components (native C loader, a .NET loader, Python and PowerShell conversion helpers) so authors can produce and embed sRDI blobs in different environments. The loader aims to behave like a proper PE loader: it preserves section permissions, supports TLS callbacks, performs sanity checks, and exposes flags to control behaviors such as header clearing, memory wiping, import obfuscation, and whether the shellcode receives the base address. ... -

SHAD0W
A post exploitation framework designed to operate covertly
It uses a range of methods to evade EDR and AV while allowing the operator to continue using tooling and tradecraft they are familiar with. Its powered by Python 3.8 and C, and uses Donut for payload generation. By using Donut along with the process injection capabilities of SHAD0W, it provides the operator the ability to execute .NET assemblies, DLLs, EXEs, JS, VBS or XSLs fully inside the memory. Dynamically resolved syscalls are heavily used to avoid userland API hooking, anti-DLL injection to make it harder for EDR to load code into the beacons, and official Microsoft mitigation methods to protect spawn processes. ...
