« Telephony Denial of Service (TDoS) Webinar Link | Main | Voice/VoIP Security Toll Fraud List of Attack »

The story almost seems to suggest they were allowing anyone to authenticate against the system, or using extensions with blank passwords or something. Allowing remote SIP connections is one thing, but allowing them from anyone without requiring even a password is something else. I'd definitely be interested to hear if you get more info. I'm trying to understand whether this was absolutely terrible security, or if I'm missing something.
