Trojaned OpenBSD CDs. Making your own ISO of OpenBSD is a trivial exercise. Hell, I make an i386 specific ISO every time a new version of OpenBSD comes out. You can still get the latest one here. People buy the CD to support the project, and that's it. No one that has the technical knowledge to need/want/use OpenBSD would be unable to make their own CD. To all the people that bought this trojaned CD, installed it and got 0wn3d, you deserved it.
