Last week, shortly after returning from the BlackHat / DefCon conferences in Vegas, I resigned my current position with Citadel Security Software to take a Vulnerability Research position with a start-up in the Internet Telephony industry called Sipera Systems. At Sipera I’ll be doing much more actual research than I was doing for Citadel, as I was in a multi-use group at Citadel who’s other responsibilities fairly regularly trumped doing security research. I’m looking forward to the change and tearing apart some Internet Telephony products and protocols!
