Would this not be a great way to infect thousands of network operations systems due to a PDF exploit? It is like "free beer" to many network operators, they just *have* to consume it. One could take control of the "network" by taking control of the systems of the people operating it and silently watch for the passwords, names, ip addresses that will enable one to take control later. I know, I am just being paranoid. There has never been an exploitable PDF exploit. Oh, wait, there has been :-) One has to admit it would be one hell of a combined social engineering and technical exploit if it could be pulled off. Gary

Over on Boing Boing:

[snip]

Here's a PDF that purports to be Michael Lynn's presentation on Cisco's critical vulnerabilities ("The Holy Grail: Cisco IOS Shellcode And Exploitation Techniques"), delivered at last week's Black Hat conference. Lynn's employer, ISS, wouldn't let him deliver the talk (they'd been leant on by Cisco), so Lynn quit his job, walked onstage and delivered it anyway. (See yesterday's post and Scheneier's take for more). 1.9MB PDF Link

I think these guys better prepare for the "slashdot effect"...
