One of the best ways to be secure, we're told, is to get a shredder. The problem with that is that if someone is motivated enough, they might be able to get information from the shreddings.
"Hey, I saw that in Bad Boys 2!" Me too - except the problem is, now it can be done by just about anyone, not just a socially inept hacker. This can be done through a software program available for download (though, of course, not for free).
On some level, very cool, but on another level, scary, especially if you have something you're trying to hide. Of course, neither of us has anything to hide, so it's all good, right?
Please note that at this point, this only seems to apply to the strip-cut shredders, which are typically the cheapest shredders. If you have a cross-cut shredder, you're safer.
