FiddleZAP is a simplified version of EKFiddle for OWASP ZAP.

With ZAP as your web proxy, you are able to flag malicious traffic based on predefined regular expressions.

Example: Alert, highlighting and tagging when a regex matches on a string within the HTML source code of a compromised website

Features

Regexes (rules) to detect malicious traffic

Rules for FiddleZAP can look for URI patterns and source code patterns (session body).

A community_rules.txt file is provided with some examples.
The user_rules.txt is your own rules file.

Rules are automatically loaded and used to scan incoming traffic (if Passive Rules script is enabled). If you want to run rules on previously captured traffic, you need to run the standalone script.
