Tor is a double-edged sword

Yes, this article's conclusions are a little obvious. An anonymizing network protects the privacy of normal users and evildoers alike. That was just about my second thought on hearing about Tor (the first was, "Cool!").

I like this article, though, because it has a step-by-step guide to running some simple Nessus scans through Tor. I haven't been using Tor in my penetration tests, partly because being anonymous isn't much of an issue, but mostly because I don't know that I trust it to work well for all the various Nessus tests. I might give this guy's method a try, though, and see how it goes.
