Show HN: Bloodhound – Grey-box attack-path discovery in Rust/Go/C++ binaries

Greetings, fellow code crafters! Ever feel like your static analysis tools are shouting wolf about non-existent bugs, while your dynamic scanners are blind to the really juicy, internal logic flaws? We've all been there, wrestling with noisy alerts and missed vulnerabilities. Well, the team behind Bloodhound has been tinkering with a clever solution, building a CLI tool that dances between the black-box and white-box worlds. They're calling it "grey-box attack-path discovery," and it sounds like a real game-changer for uncovering those hidden gems that slip through the cracks.

At its heart, Bloodhound crafts a detailed map of your codebase's internal architecture, understanding how different pieces connect and interact. Then, it unleashes parallel execution engines, essentially spinning up thousands of mini-dev environments to poke and prod your code. This isn't just random fuzzing; it's guided exploration that validates potential bugs by observing real runtime behavior against the intended logic. This allows it to pinpoint tricky issues like race conditions, state inconsistencies, and even map out how external inputs can thread through your system to trigger a vulnerability, complete with replayable exploit flows. It's a powerful approach, especially for those more sophisticated systems where deep, validated testing is paramount.

The beauty of this craftsman's approach lies in its practical output. Bloodhound not only finds these complex logic and security holes but also generates remediation reports that precisely pinpoint the offending lines of code and their downstream consequences. It's designed for privacy, running locally, and currently supports a wide array of languages from Rust and C++ to Python and JavaScript, along with IaC tools like Terraform. If you're maintaining a complex project and curious to see what hidden flaws might be lurking, they're even offering to run their engine on your repos for early beta users. This feels like a tool built by developers, for developers, aiming to bring clarity and confidence to our most intricate code.
