Phreaking Resurrected

Posted by Xavier Ashe on November 13, 2005

Industry sources have confirmed that a new
generation of “phreakers” may be able to manipulate data switched
through a hybrid TDM-VOIP network, allowing them to make free calls. Industry
executives confirmed that the hack was in the wild, although they could
not provide estimates of how serious the exploit was. News of the
exploit was originally published by the Broadband Business Forecast, a subscription newsletter for the broadband industry.

In a normal conversation, a caller is not charged if
the receiver does not pick up the handset, and the call is not diverted
to voice mail or to some other service – it's the receiver's decision
whether to respond to the call, and, indirectly, to charge the person
making the call. The exploit fools the billing system into thinking the
call was never made, when in fact the receiver did respond ad a
conversation took place.
