Threat of the Week: TDoS Will Hang Up On You
DDoS (Distributed Denial of Service) may be getting all the recent press, but now the FBI, Homeland Security and several more federal agencies have issued a no-nonsense warning about a spike in the number of TDoS (telephony denial of service) attacks which wipe out a victim’s telephone service.
The focus of the warning was a jump in TDoS against public sector emergency services agencies (police, ambulance, etc.) The warning noted: “The perpetrators of the attack have launched high volume of calls against the target network, tying up the system from receiving legitimate calls. ... Many similar attacks have occurred targeting various businesses and public entities, including the financial sector” (emphasis added).
