US Security Services May 'Have Moles Within Microsoft,' Says Researcher
Barence writes "U.S. government officials could be working under cover at Microsoft to help the country's cyber-espionage programme, according to one leading security expert. According to Mikko Hypponen, chief research officer at security firm F-Secure, the claim is a logical conclusion to a series of recent discoveries and disclosures linking the U.S. government to 2010's Stuxnet attack on Iran and ties between Stuxnet and the recent Flame attack. 'It's plausible that if there is an operation under way and being run by a U.S. intelligence agency it would make perfect sense for them to plant moles inside Microsoft to assist in pulling it off, just as they would in any other undercover operation,' he said. 'It's not certain, but it would be common sense to expect they would do that.'"
We can get even simpler and easier, MS already gives the military access to their source code so that it can be reviewed. This is a requirement for all the software used on the most secure systems.
It has always been viewed as a joke around here, because unless they are going to fix the bugs themselves, having the source isn't going to make windoze take extra care about your data.
So the simplest and most obvious answer is, they didn't need to sneak in, and they didn't need to make threats either.
