American fuzzy lop is a security-oriented fuzzing tool that employs a novel type of compile-time instrumentation and genetic algorithms to automatically discover clean, interesting test cases that trigger new internal states in the targeted binary. This substantially improves the functional coverage for the fuzzed code. The compact synthesized corpora produced by the tool are also […]

Anyway today’s story is about the recently released tool cross_fuzz by Michal Zalewski and an inadvertent leak that have occurred. tl;dr version is something like this: Michal Zalewski writes a DOM fuzzer, fuzzes IE, finds flaws, Chinese dudes […]
Stompy – The Web Application Session Analyzer Tool
A new tool dealing with web sessions was recently announced, it’s called stompy, a free tool to perform a fairly detailed black-box assessment of WWW session identifier generation algorithms. Session IDs are commonly used to track authenticated users, and as such, whenever they’re predictable or simply vulnerable to brute-force attacks, we do have a problem. […]
