A vulnerability-evaluation platform for analysis systems. Measures and compares automated security tools through reproducible experiments, explicit metrics, and reviewable evidence.

Security Evaluation · Benchmark · Vulnerability Detection

Program-analysis infrastructure for source-level reasoning. Built with C++ and Clang AST, with a focus on templates, namespaces, class hierarchies, initialization, and explicit source relationships.

C++ · Clang · LLVM · AST · Program Analysis

A reproducible environment for indirect prompt-injection research. Evaluates attacks against LLM agents and tool-using systems inside controlled Docker-based experiments.

Agent Security · Prompt Injection · Docker · Android

More Systems

  • ctf-lab — practical CTF exercises and offensive-security methodology.

  • netwatch-cli — lightweight network and system inspection for security-engineering workflows.
