It sounds pretty unbelievable to me. To make good on some of the claims made in the article they'd have to bypass not only Vista's security, but also the virtual memory system of the CPU. Unless their exploit can load code into
the kernel that seems unlikely.
Whatever the case, I'll be interested to see what they've come up with. But until I've seen them in action I have my reservations about things being as bad as the article claims.
If its anything like all the other killer vista/windows exploits.. it'll
just be a "YEA ITS COMING, JUST YOU WAIT!"... and ya - still waiting.
