Paros Proxy




Paros 3.2.11 has been released. This version is a maintenance release with a useful feature requested by various users. All users are recommended to upgrade to this version.

One of my favourite proxy options, along side the Burp Proxy (evolved into Burp Suite).

Paros labels itself as MITM Proxy + Spider + Scanner plus anything else you want it to be, it is a pretty neat piece of software.

It’s particularly useful for testing web applications and things such as insecure sessions.

Paros is free of charge and completely written in Java. Through Paros’s proxy nature, all HTTP and HTTPS data between server and client, including cookies and form fields, can be intercepted and modified.

A Java based HTTP/HTTPS proxy for assessing web application vulnerability. It supports editing/viewing HTTP messages on-the-fly. Other featuers include spiders, client certificate, proxy-chaining, intelligent scanning for XSS and SQL injections etc.

These proxies have a different purpose than those personal type proxies like Proxomitron which are intended to protect you, clean adverts, block spyware and so on. Proxies like Paros and Burp are meant for examining the security of applications and web application auditing.

You do need Java Run Time Enviroment (JRE) 1.4 (or above) to install Paros.
