According to a report Microsoft helped the NSA get around its encryption systems so the agency could more effortlessly spy on users of its services. Microsoft supposed its partnership with the NSA only took place since legal obligations required it to do so. The revelations come as some technologists start work on services they say will be impermeable to spying.
The credentials show that the NSA had admittance to most of Microsoft's flagship products including Hotmail, Outlook.com, Skydive and Skype. The credentials seen by The Guardian are apparently from the NSA's Special Source Operations office which oversees the links between the agency and tech firms. These also show that the access the NSA enjoyed made it far easier for cleverness workers to get at accounts on many Microsoft services.
