Not a hoax if you read that news carfully and have looked at what their software does. Basicly they are refering to vulnarabillities that already where in Windows before SP2. They also say SP2 have closed some gaps, but not all. Their software scans for certain signatures and is using also heuristic intrusion scanning.

imho, just disguised promoting of their software. That doesn’t mean ofcourse that there are no gaps in Windows and that SP2 isn’t solving them all. (which we already knew)
