Quarkslab is building new tools to analyze what is going on our systems, from an ARM dynamic binary instrumentation to symbolic execution framework like Triton (http://triton.quarkslab.com) and several other advanced software security tools. System audits and vulnerability research must be taken to a new stage, as code bases are growing faster and faster. New tools need to be designed to help the security researchers in their daily work.
