But turns out, it's not even close to being the WMD that people were afraid of (that's a "weapon of mass destruction," in case you were born after the year 2000) and is actually kind of useful, particularly for the security / hacker community. People have used it for penetration testing recon, for security research, for a quick check of their own website, or just for personal use. The thing is, unless you're a security researcher who keeps PunkSPIDER open in a tab in your browser, you probably won't remember to go there and check out a website to make sure it's safe before you give them your credit card info.
To make it more accessible to the average user, the team behind PunkSPIDER released a Chrome extension that sits in your nav bar and tells you if PunkSPIDER has found any vulnerabilities on the site you're on. If it does, you get a red x, if it doesn't, you get a green check. It's stupid simple and it's free.
Here's a link to dl the extension https://chrome.google.com/webs... and here's a demo video on how it works http://www.youtube.com/watch?v.... There are some other videos under the same account that you can watch if you want to know more about the PunkSPIDER project.
There are plans to release a Firefox plugin soon, too, which will be nice because it's arguably a more ubiquitous browser than Chrome. Still, I'm switching to Chrome now just for this extension."
