The main vector of attack from what I have understood is the QR code generation. Satoshi chose the only QR code generator that does not have an NSA back door built in. It is a plausible thought that Satoshi worked at the NSA and moved away from the project to protect himself knowing if the project went on long enough without him getting fingered, There would be no stopping it. The CIA is good at imperialism and resource extraction, Government coercion, Government coup de gras, But not good at monitoring the NSA for emerging decentralized financial systems. Bureaucracy brought down the communists and it will bring down the western system as well.
