Edward Moyer cnet.com Here's one of the latest tidbits on the NSA surveillance scandal (which seems to be generating nearly as many blog items as there are phone numbers in the spy agency's data banks). Earlier this week, Techdirt picked up on a passing mention in a Brazilian news story and a Slate article to point out that the US National Security Agency had apparently impersonated Google on at least one occasion to gather data on people. (Mother Jones subsequently pointed outTechdirt's point-out.) Brazilian site Fantastico obtained and published a document leaked by Edward Snowden, which diagrams how a "man in the middle attack" involving Google was apparently carried out. A technique commonly used by hackers, a MITM attack involves using a fake security certificate to pose as a legitimate Web service, bypass browser security settings, and then intercept data that an unsuspecting person is sending to that service. Hackers could, for example, pose as a banking Web site and steal passwords. The article by Brazil's Fantastico mentions a hitherto unknown GCHQ spy program called "Flying Pig." This prompted a Twitter quip from Electronic Frontier Foundation attorney Kurt Opsahl: "PRISM, Flying Pig. Someone in the surveillance state has a thing for Pink Floyd album covers."The technique is particularly sly because the hackers then use the password to log in to the real banking site and then serve as a "man in the middle," receiving requests from the banking customer, passing them on to the bank site, and then returning requested info to the customer -- all the while collecting data for themselves, with neither the customer nor the bank realizing what's happening. Such attacks can be used against e-mail providers too. to read more click here: cnet.com
