Been a very fun/interesting morning. Since so much has gone on, I figured I'd share. We have seen a larger than normal, if not, one of the largest attacks against some of our VoIP and video conferencing systems today. Initially, we fielded a report of a "system gone bad" followed by another, then another, and another. This has now carried on into some of our videoconference units (LifeSize). Because our goal is to get telephony up and running, there was not much we could do via incident response, so I have little to add on attack vectors however, I will state that PBXNSIP has been the primary target, with about a dozen of these being hit pretty hard to the point I've had to block all, stop the software and re-start it. My dealings with vulnerability disclosures has been that, vendors don't care, so if there is something specific with PBXNSIP, no one knows, and due to their political bickerings in house, no one is going to fix it. So for anyone using this software, long weekend dictates: "lock your **** down." Same goes for LifeSize. -- =+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ J.
