Hackers, despite what you may have heard, have ethics, but apparently a couple of giddy Frenchies though they would be "1337" and sniff a few packets on a line designated as secure at hacker convention Black Hat 2008.  Turns out monitoring traffic when parties involved are not informed is a felony.  What a surprise.  Furthermore surprising is that FBI agents attend Black Hat (I’m being sarcastic, it’s not surprising).

Lest we all forget the NBC "shock" reporter…

Explanation:
Reporters are welcomed at hacker conventions like Black Hat and Defcon, but they are also required to declare themselves as reporters and wear a press badge.  This woman was hiding a camera in her purse and recording the events.  Unsurprisingly she was caught very early in the con.  She was attempting to do a shock piece for NBC Dateline on hackers and federal agents.  Unfortunately, aside from the usual fun of "spot the fed" (where the people try and point out who they think are federal agents in good fun but no real seriousness), this woman would have revealed the identities of many agents and otherwise.  Hence it’s a big deal.
