Following the story yesterday about Cisco suing a security researcher for doing a presentation on a huge vulnerability in Cisco routers, it appears the two sides have reached a settlement that basically says the guy will never speak about it again. He isn't to give the presentation again anywhere and all videos of the presentation were to be handed over to Cisco. Before the presentation, of course, Cisco employees had already ripped all the supporting material out of conference handouts, so that's missing also. So, the question is, can Cisco really make this disappear? Obviously there were some people who attended the session, and since the conference is all about hacking, you have to imagine a number of them fully understood the vulnerabilities being discussed. Are they all going to have to shut up about it too? It seems like a fairly difficult thing to try to sweep it under the rug and pretend it didn't happen.
