I think it's more likely that they used something targeting the browsers, maybe with 0-days maybe not. But it doesn't seem to me that the FBI put much effort into this whole thing, maybe it was more a concern for Facebook than for them. As I understand it knowing that someone is using Tor is usually trivial, the exit nodes normally set a reverse DNS record that signals it and there are exit nodes blacklists

> As I understand it knowing that someone is using Tor is usually trivial Yeah, Facebook almost certainly receives a lot of attempted traffic from those relatively few TOR exit node IPs, so I'm sure part of their system is aware that they are effectively proxy IPs.
