Google releases skipfish, internally used tool for scanning apps

Skipfish by Google is an internally developed tool used as an 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. The tool is meant to provide accurate and meaningful results.
