instrumentation_callbacks

instrumentationcallbacks Instrumentation callbacks are quite a fun undocumented part of Windows. All the code in this repository is released under the MIT license. This repository uses google style C++ spacing. PRs are welcome if you find issues, bugs, or believe a specific feature should be adde...

windiff

WinDiff About WinDiff is an open-source web-based tool that allows browsing and comparing symbol, type and syscall information of Microsoft Windows binaries across different versions of the operating system. The binary database is automatically updated to include information from the latest Windo...

acheron

About Acheron is a library inspired by SysWhisper3/FreshyCalls/RecycledGate, with most of the functionality implemented in Go assembly. acheron package can be used to add indirect syscall capabilities to your Golang tradecraft, to bypass AV/EDRs that makes use of usermode hooks and instrumentatio...

strace

strace - the linux syscall tracer This is strace -- a diagnostic, debugging and instructional userspace utility with a traditional command-line interface for Linux. It is used to monitor and tamper with interactions between processes and the Linux kernel, which include system calls, signal...

sylvia

iOS AArch64 Syscall Analyzer An IDA Pro script that scans an AArch64 binary for SVC instructions, resolves the BSD syscall number from the X16 register, and presents every result in a rich dockable UI, with per-syscall occurrence navigation and live man-page documentation fetching. Built for iOS ...

SunnyDayBPF

SunnyDayBPF SunnyDayBPF is an eBPF-based post-syscall user-buffer telemetry deception research technique originally proposed and researched by Azizcan Dastan. The technique investigates whether data observed by user-space security, logging, or telemetry agents can be altered after a read-like...

CVE-2026-73860

CRIU is a checkpoint and restore tool for Linux. Prior to 4.2.1, CRIU injects a syscall;int3 sequence at the start of the first executable virtual memory area and resumes the target process to execute parasite code. Malicious code in the target process can keep an rseq critical section armed over...

seccomp-tools

Seccomp Tools Powerful tools for seccomp analysis. This project is aimed primarily but not exclusively at analyzing seccomp sandboxes in CTF pwn challenges. Some features are CTF-specific, but they're just as useful for analyzing real-world seccomp filters. Features Dump - Automatically dumps...

snoop

snoop A syscall tracer for Linux, built on eBPF. Like strace but with a live TUI, smart filters, and argument decoding you can actually read. $ sudo snoop curl https://example.com 0.001 curl1234/1234 openatATFDCWD, "/etc/ssl/certs/ca-certificates.crt", ORDONLY = 4 0.002 curl1234/1234 read4,...

kafel

WHAT IS IT? Kafel is a language and library for specifying syscall filtering policies. The policies are compiled into BPF code that can be used with seccomp-filter. This is NOT an official Google product. Usage With verbose error reporting struct sockfprog prog; kafelctxtt ctxt = kafelctxtcreate;...

azazel

Azazel A lightweight eBPF-based runtime security tracer purpose-built for malware analysis sandboxes. Drop a sample into an isolated container, and Azazel captures every syscall, file touch, network connection, and suspicious behavior, then hands you a clean JSON stream of everything that happene...

exrop

Exrop Automatic ROP chain generator for x86-64 binaries, powered by Triton symbolic execution. Features Set registers to constants or other registers rdi=0x41414141, rdi=rax Write to memory constant and register-based addresses/values Write strings/bytes to memory Function calls with mixed...

HallWatch

HallWatch Copyright C 2026 Adam Zypherion — licensed under GPL-3.0. Indirect syscalls are simple once you have seen one. The loader walks ntdll, reads the SSN out of Nt prologue, finds the 0F 05 two bytes further in, sets r10/rax/rdx/r8/r9 itself, and jmps straight at those two bytes. The syscall...

SysWhispers2

SysWhispers2 SysWhispers helps with evasion by generating header/ASM files implants can use to make direct system calls. All core syscalls are supported and example generated files available in the example-output/ folder. Difference Between SysWhispers 1 and 2 The usage is almost identical to...

DeadDialect

DeadDialect Every boot speaks a different language. Yesterday's binary is today's dead code. A session-unique RISC-V ISA remapping system. Every time the system boots, it generates a fresh cryptographic permutation of the instruction set. Binaries compiled for one session are cryptographically...

ksentinel

ksentinel - Kernel Syscalls Integrity Monitor Overview ksentinel monitors critical kernel functions and the syscall table for unauthorized modifications. It detects common syscalls that are targeted by most rootkits including ftrace hooks, kprobes, and syscall table hijacking. Features Function...

hades

About Hades is a proof of concept loader that combines several evasion technques with the aim of bypassing the defensive mechanisms commonly used by modern AV/EDRs. Usage The easiest way, is probably building the project on Linux using make. git clone https://github.com/f1zm0/hades && cd hades ma...
