Evidence points to another leaker at the NSA
> In addition, if Russia had stolen the hacking tools, it would be senseless to publicize the theft, let alone put them up for sale. It would be like a safecracker stealing the combination to a bank vault and putting it on Facebook. Once revealed, companies and governments would patch their firewalls, just as the bank would change its combination.<p>Why would this be bad for Russians (if this was indeed the Russians)? We can/should assume that Russia has it's own methods of infiltrating systems. The value of this data to them would be knowledge of how it's done, not necessarily hoarding and replicating how the NSA does it. If anything, having vendor's patch exploits that they're not using, but their enemy is, would be a great chess move.
