Main article: Web exploitation tools

Kolkata is a web application fingerprinting engine written in Perl that combines cryptography with IDS evasion. Kolkata uses session splicing for IDS evasion and configurable checksums of static files in order to determine the version of a web application.

Dependencies

• LibWhisker2 - This comes bundled in the tarball, with nikto, and a variety of other tools on this site.
• YAML::XS - Install with cpan in bash (cpan -i YAML::XS)

Usage

 kolkata.pl -d domain.tld [-v -p [remote_path_to_web_application]]

• kolkata requires a directory called sigs in its directory
• The sigs directory must contain properly formatted yml files with checksums.

Source

• Download : http://www.blackhatacademy.net/kolkata.tgz
