Google releases web application security scanner

Google released Skipfish, a free fully automated, active web application security reconnaissance tool. It prepares an interactive sitemap for the targeted site by carrying out a recursive crawl and dictionary-based probes.

The resulting map is then annotated with the output from a number of active (but hopefully non-disruptive) security checks. The final report generated by the tool is meant to serve as a foundation for professional web application security assessments.

Key features:

• High speed: Pure C code, highly optimized HTTP handling, minimal CPU footprint – easily achieving 2000 requests per second with responsive targets.
• Ease of use: Heuristics to support a variety of quirky web frameworks and mixed-technology sites, with automatic learning capabilities, on-the-fly wordlist creation, and form auto completion.
• Cutting-edge security logic: High quality, low false positive, differential security checks, capable of spotting a range of subtle flaws, including blind injection vectors.

The tool supports Linux, FreeBSD 7.0+, MacOS X, and Windows (Cygwin) environments.
