I listen to alot of different podcasts and over the weekend I listened to the “Security Now” podcast and I thought it was fascinating. The guy who does the podcast is Leo Laporte (of Tech TV) and he speaks with Steve Gibson every week about various security issues.
This one was about IRC botnets (or Internet Weaponry as he calls it). I have vaguely heard about these things before but I never realized how powerful they are. Anyways this podcast is now a weekly “must listen” for me.
