Open source Security R&D

We publish real, testable artifacts—kernel modules, compiler passes, and analysis tools—so defenders can measure, break, and harden systems.

What we do

We publish verifiable security research—code, papers, and reproducible experiments—focused on Linux kernel internals and compiler toolchains. Our work helps blue teams test detection, vendors harden products, and researchers compare techniques apples-to-apples.

  • Kernel research. Loadable modules, stealth/detection studies, forensics evasion vs. countermeasures.

  • Compiler security. Obfuscation and hardening passes; analysis that exposes optimization-stage blind spots.

  • Tooling. Scripts, debuggers, and test harnesses that make experiments repeatable.

  • Trainings & knowledge transfer. Hands-on, lab-first workshops with ready-to-run QEMU images and reproducible labs; teams leave with working setups, checklists, and code.

Why open source

  • Transparency beats claims. Anyone can reproduce our results.

  • Faster hardening. Public code shortens feedback loops between researchers and vendors.

  • Shared baselines. The community can test against the same artifacts and improve them together.

Security Research Services

We specialize in enhancing security for Linux kernels and compilers through innovative open-source projects.

Kernel Module Security

Our loadable kernel module challenges security for Linux kernel versions 5 and later, ensuring robust proactive defenses.

Compiler Passes & Security

We provide a collection of compiler passes and tools aimed at identifying vulnerabilities in x86, ARM, and RISC-V binaries.

We deliver comprehensive, hands-on training in Linux Kernel Threats & Defenses.

The screen shows a text editor with various files and folders listed on the left-hand side, while the main coding area is open with a command line interface. There are green text outputs typical of command line operations performed on a black background.

Text written on a computer screen displays programming code with comments. The code uses C syntax, featuring the use of 'typedef' to define character constants. Some text appears in green, suggesting it is a comment, while other code is in blue and white, indicating keywords and standard text respectively.
