Google’s School for Hackers

Google is offering programmers their own personal sandbox application—called Jarlsburg—and hints of how to exploit the common vulnerabilities purposefully left in it. Although Google is basically walking folks through how to attack apps, publicizing this info is a necessary evil in order to build safer programmers. We have to start thinking of each line of code, cookie, HTTP request, and configuration option as another attack surface.

The table of contents lists the who’s who of vulnerabilities (though there are a lot more out there). Several of these attacks no one would’ve even dreamed of a few years ago, so the sad reality is that the web is chock full of vulnerable “legacy” apps just waiting to be exploited—unless we can fix them in time.
