Odd new form of malicious spam

Malicious email

 I received the email displayed at the right. While Larry Grinnell is indeed a friend of mine who sends me email, the sender's email address was not his. This is one of several emails I've received, all extremely brief, and all with the exact same, format. The Subject line contains an exclamation. The body text contains my name and a single URL. I started saving them and experimenting with the URLs.

The first URL led to a place in Russia that displayed a weight-loss ad. I used a VM running Chrome to open it. When I used the same VM to open the more recent one (shown above) the VM crashed. I expected that. What I didn't expect was for it to take my whole desktop down, too.

Cloud Computing Discovers Covert Channels

A SANS Handler Notebook entry by Toby Kohlenberg reports on data leakage in cloud computing, and links to a terrific paper from some UCSD/MIT people: Ristenpart, Tromer, Shacham, and Savage.

If we set the wayback machine to the early 1970s, we find a paper by Butler Lampson about something called the confinement problem. It's the same thing. Ristenpart et al pick up some of the threads (like noninterference) though their paper doesn't point all the way back to Lampson.

This is a hard problem to solve. The only defense right now is if attackers lack the motivation to exploit it.
