Awesome angr

A collection of resources/tools and analyses for the angr binary analysis framework. This page does not only collect links and external resources, but its meant to be an harbour to release any non-official extensions/tool/utils that can be useful when working with angr.

ExplorationTechniques 📁

A collection of exploration techniques written by the community

SimgrViz: an exploration technique that collects information regarding the states generated by the SimulationManager and creates a graph that can be later visualized to debug the analyses (.dot file).
MemLimiter: an exploration technique to stop the analysis when memory consumption is too high!
ExplosionDetector: stop the analysis when there are too many states or other critical errors happen.
KLEECoverageOptimizeSearch: KLEE technique to improve coverage.
KLEERandomSearch: an ET for random path selection.
LoopExhaustion: a loop exhaustion search strategy.
StochasticSearch: an ET for stocastic search of active states.
HeartBeat: An exploration technique to make sure symbolic execution is alive and provides some utility to gently hijack into the DSE while it is running.
