I could see them more easily subverting chip designs themselves then trying to subvert the entire compiler ecosystem.

Given that compilers are both a fairly easy to attack and amazingly convenient target, it wouldn't surprise me if the NSA has subverted a few specific compilers that are in common use. An attack of this nature has been hypothised since the early to mid-1980's. They would have to be amazingly dense not to have at least considered it. On the flip side, the NSA likes to do things where it has the least opportunity to be caught. Compiler subversion, while not "easy" to catch by any means, might offer too big a risk of being caught for them to do it. Being that they have a multitude of weirdly named programs specifically set up to compromise software, the evidence would lean towards they haven't done it but I'm sure it was, at the very least, discussed. -- Kelly John Rose Toronto, ON Phone: +1 647 638-4104 Twitter: @kjrose Skype: [2]kjrose.pr Gtalk:[3]iam@kjro.se MSN:[4]msn@kjro.se Document contents are confidential between original recipients and sender.
