fair enough; i'll suggest that the vast majority of ISP's don't have the equipment or skill to implement these kinds of MITM attacks. (can you imagine trying to play eve against arbitrary customer traffic on an OC12+ link? that cisco switch isn't going to cut it...) they are out to make a profit, and spending non-trivial amounts of money for something that can only negatively impact the customer experience is a total loss. (note that even CALEA had to sweeten the deal for carriers just for passive eavesdropping capability which is trivial compared to complex layer MITM attacks) i'd love to know more about any such ISP implemented MITM "investigative techniques" that may have been used; i've never heard of such, but perhaps they are simply uncommon and rarely publicized. best regards,
