Perhaps most disturbing is how chipper they are about it. TechCrunch writes:
The NSA has been spying on the goings-on at the United Nations’ New York headquarters for nearly a year.
German news magazine Der Spiegel cites a multitude of documents that “stemmed” from Edward Snowden which purport (among other things) that the NSA first managed to crack the UN’s video conferencing system during the summer of 2012.
Some of the documents speak nicely to the sort of banality those involved ascribed to their actions — “The data traffic gives us internal video teleconferences of the United Nations (yay!),” one of them reads.
Also on that list of targets is the International Atomic Energy Agency and the European Union, though at this point it’s unclear what exactly the NSA has managed to dig up on either of those bodies. Perhaps unsurprisingly, Der Spiegel notes that [the NSA's activity] “has little or nothing to do with warding off terrorists.”
