A while back I stumbled upon an interesting issue with a hacked Asterisk server. It was routing calls to FreeConferenceCall.com and other free conference numbers.

- StudentStuff 8y agoToll fraud is quite common due to the VOIP industry not valuing security. Combined with free conference calling numbers costing a bit to call (and calls to these numbers lasting a fair while), I'm not surprised that most of the traffic was headed to these numbers.
- nwilkens 8y agoAny idea how this Asterisk server would have been added as a route? These callers that were recorded, were not the ones trying to leverage the hacked server, but rather just dialed the number and were routed through it.
- mkching 8y agoOne common exploit if only one user account is hacked is to set up a forward to a specific high cost number that receives a lot of traffic. There are carriers who aggregate these routes and even blend them in with legitimate routes and then resell them to other carriers at a low cost.
