Julie188 writes "Thousands of people got a nasty e-mail this morning from Cisco. The company was warning people that its attendee registration database for its Cisco Live 2010 event was hacked. Cisco Live 2010 is the company's annual user conference, held last week in Las Vegas with an estimated 18,000 in attendance. If it's not embarrassing enough for a company that sells security gear to get hacked, the e-mail also went out to people who didn't register and didn't attend the event. That raises questions about exactly what database was pried open and how bad the damage is. Cisco's e-mail said the hole was quickly closed and only business-card type information was exposed."pa href="http://www.facebook.com/sharer.php?u=http%3A%2F%2Fyro.slashdot.org%2Fstory %2F10%2F07%2F08%2F1841238%2FCisco-Says-Vegas-Conference-Attendees-Information-Was-Leaked" target="_blank" title="Share on Facebook"img src="http://a.fsdn.com/sd/facebook_icon_large.png"/a a href="http://twitter.com/home?status=Cisco+Says+Vegas+Conference+Attendees' +Information+Was+Leaked%3A+http%3A%2F%2Fbit.ly%2F9 FQT0z" target="_blank" title="Share on Twitter"img src="http://a.fsdn.com/sd/twitter_icon_large.png"/a/ppa href="http://yro.slashdot.org/story/10/07/08/1841238/Cisco-Says-Vegas-Conference-Attendees-Information-Was-Leaked?from=rss"Read more of this story/a at Slashdot./ppa href="http://feedads.g.doubleclick.net/~at/n4NuM1EQBR-0W7nJxI-wY52TChc/0/da"img src="http://feedads.g.doubleclick.net/~at/n4NuM1EQBR-0W7nJxI-wY52TChc/0/di" border="0" ismap="true"/img/abr/a href="http://feedads.g.doubleclick.net/~at/n4NuM1EQBR-0W7nJxI-wY52TChc/1/da"img src="http://feedads.g.doubleclick.net/~at/n4NuM1EQBR-0W7nJxI-wY52TChc/1/di" border="0" ismap="true"/img/a/pimg src="http://feeds.feedburner.com/~r/Slashdot/slashdotDevelopers/~4/eI9ThXtqdGE" height="1" width="1"/
