Telephonic DoS tied to Ukraine power grid takedown
The Ukrainian DoS attack took out the company's call center so its customers could not call and let workers know that service was being disrupted, according to a published report. A telephonic DoS attack works in the same manner as one hitting a computer system, but in this case a call center is overwhelmed with calls to shut it down.
In addition, with the telephone system down the utility company staffers could not communicate effectively to fix the problem.
Telephonic DoS attacks can be used to obfuscate any type of attack to attract an IT department's attention while the real assault takes place against another segment of the network.
