FBI Issues Warning about Telephony Denial of Service Attacks

By Rich Steeves, TMCnet Managing Editor


The FBI’s Internet Crime Complaint Center (IC3) has a warning for you. The organization, which aims to protect American citizens against online crimes, frequently posts updates, letting us know how to make our passwords safer, how to defend against the latest scams and warning us about trends in cybercrime. With Telephony Denial of Service (TDoS) attacks on the rise, it is important to aware of this increasing danger.


In a TDoS attack, criminals hack into automated VoIP dialing programs in order to flood the phone lines of their victims, inundating them with hundreds or thousands of calls. The biggest worry in this regard is when hackers attack emergency service numbers, putting them out of commission and therefore unable to attend to genuine emergencies.

These criminals are also attacking individuals by using VoIP to spoof the telephone number of the police department. The hackers then tell the victims that there is warrant out for their arrest for defaulting on a loan. Then the same criminals use VoIP to spoof the victim’s number, placing multiple harassing calls to the police, sending the cops to the victim’s doorstep. It’s a creepy and sinister plan to say the least.

Fortunately, for those of us who are concerned about these sorts of attacks, there are solutions out there that offer fraud detection capabilities. For example, SDReporter, from least cost routing and VoIP fraud specialist TransNexus (News - Alert), has new and improved fraud detection capabilities. It can recognize fraud based on IP address, group ID or caller idea, and can stop call frauds from occurring. For more information on fraud detection solutions, click here.
