Bugwise is a free online web service at www.bugalyze.com to perform static analysis of binary executables to detect software bugs and vulnerabilities. It detects bugs using a combination of decompilation to recover high level information, and data flow analysis to discover issues such as use-after-frees and double frees. Bugwise has been developed over the past several years and is implemented as a series of modules in a greater system that performs other binary analysis tasks such as malware detection. This entire system consists of more than 100,000 lines of C++ code and a scalable load balanced multi-node Amazon EC2 cluster. In this talk, I will explain how Bugwise works. The system is still in the development stage but has successfully found a number of real bugs and vulnerabilities in Debian Linux. This includes double free, use-after-free, and over 50 getenv(,strcpy) bugs statically found from scanning the entire Debian repository.
