>This is all really just an expansion of "they're worried about some sort of liability." In any case that's by far the likelier of the two; I can't imagine you could sell IP related to this.

I more or less agree that liability seems more likely, but I have no idea what the nature of the attack is, so it's always possible it's an offshoot of some other research they are doing which can be patentable. Alternatively, it could be that CMU procedure is to require approval for all talks for brand and IP protection reasons and he just hasn't gone through the proper procedure, so in the meantime they pulled it (rather than pulling it in response to an actual analysis of the talk). This last one seems unlikely, though, as you'd imagine there was no rush to pull the abstract (which contained no details).

At a school like CMU it's hard for me to believe they'd cancel a researcher's talk because it wasn't properly disclosed. It'd create a headache for the IP team, but they wouldn't cancel the talk. That just makes them look awful.
