Couldn't resist! Ok this article over at SlashDot highlights the ingenuity (and perhaps the desperation) of hackers and their ilk. There are some blogs creeping into the industry that are honey traps, waiting for unsuspecting people to come along, download something and get hit with virii and all kinds of nasty surprises.
Generally speaking, these are spread through IM's telling you about new blogs, and hold malicious code intended to screw with you. Supposedly, only about 200 or so of these exist, and in a multiverse of 8 million blogs that's not too many, and undoubtedly they will be unmasked quickly. Be warned!
