Computers, mostly in the Middle East and most of those in Iran, are being found with a new virus which is being called Flame or Flamer. This virus appears to be gathering intelligence by taking screenshots and recording sound which are then forwarded to its command-and-control servers. It’s a much large program than Stuxnet. Unlike Stuxnet, it doesn’t appear to be designed to break what the computer is controlling. It appear to simply be spying.
Wired has some details here. Of course, the rumor mill is pointing fingers at Israel as the source of the virus.
UPDATE—And here is the BBC’s online report.
