How to Turn Your Browser Into a Weapon

"I wrote about three of my favorite Firefox extensions that help me stay safe when I'm browsing the darker areas of the Web and incoming email. Today, let's look at three other extensions: Those that can turn Firefox into a feature-filled, Web-hacking weapon. These extensions aren't required to use Firefox for hacking Web applications, but they certainly make it a lot easier.

If I could only install one "offensive" extension, it would absolutely be Tamper Data. In the past, I used Paros Proxy and Burp Suite for intercepting requests and responses between my Web browser and the Web server. These tasks can now be done within Firefox via Tamper Data -- without configuring the proxy settings.

If the Website you're trying to break into requires a unique cookie, referrer, or user-agent, intercept the request with Tamper Data before it gets sent to the Web server. Then, add or modify the attributes you need and send it on. It's even possible to modify the response from the Web server before the Web browser interprets it. It's a very nice tool for anyone interested in Web application security.

Paros and Burp both have features not yet available in Tamper Data, such as site spidering and vulnerability scanning. Switching over to one of them as a proxy is much easier with SwitchProxy, which helps you quickly configure Firefox to use Paros and Proxy. It's not a purely "offensive" extension, but SwitchProxy it makes the configuration of proxies for Firefox much quicker.

Extensions? Pffft. In Firefox, you can do anything with fairly simple bookmarklets, from penetration to DOS attacks. Gimme some NEWS, Vern!
