Federal communications Commission, the United States requires operators to redirect calls to 911 dispatch centers without proper identification of the caller.


Even a relatively small botnet consisting of 6 million infected smartphones can cause major disruptions in telephone system centralized emergency 911 in one US state, say Israeli researchers.

According to experts of the research centre in cyber security at University named after Ben-Gurion, one of the key problems is that the Federal communications Commission, the United States requires operators to redirect calls to 911 dispatch centers without proper identification of the caller and check the status of the subscriber. This makes it difficult to prevent made with mobile devices TDoS attacks (telephony denial-of-service, since the attacker can use different IMEI, not to be in the black list.

Experts demonstrated the attack scenario involves the formation of a botnet of infected Android smartphones. Intizarova the device, an attacker C&C server to send to the smartphone, the team is always to dial 911. In addition, different types of malware can embed the audio in the 911 call to the dispatcher was quickly able to distinguish real calls from automatic.

Researchers have created a small experimental mobile network that allowed them to test TDoS attacks against 911. As it turned out, the botnet of a total of 6 million infected smartphones can seriously disrupt service in a single US state such as North Carolina, and the use of 200 thousand devices can lead to failures in the 911 throughout the country.
