Out-of-band signaling has the following advantages: It allows for the transport of more data at higher. It allows for signaling at any time in the entire duration of the conversation, not only at the beginning of the call. It enables signaling to network elements to which there is no direct trunk connection.

The SS7 is also used to implement the network roaming when users need to use different network providers. A hacker accessing the SS7 system can snoop target users, locate them, and transparently forward calls.

The access to the SS7 system is possible by using any number of networks. In response to the disclosure of security issues related to the SS7 protocol, telco bodies, and operators, including the GSMA, have introduced monitoring services to prevent intrusions or abuse.

Recently a group of hackers demonstrated how spy on mobile users simply using their phone numbers; they have chosen as a target complacent US Congressman. There is nothing new in the revelation because the telco community was aware of the technique adopted by security experts, the same team illustrated in the past the technique that exploits security flaws in the Signalling System No.

They could hear any call. Pretty much anyone has a cell phone. It could be stock trades you want someone to execute. It could be a call with a bank.

Karsten Nohl and his team investigated the presence of security flaws in the SS7 system back in Despite the huge investment in security made by telco companies, the adoption of flawed protocols exposes customers to serious privacy and security risks. Despite the access to the information managed by operators is restricted to the technical operation of the network, voice calls, and short messages can be initiated to your phone number from almost anywhere in the global SS7 network.

The packets were revealing the subscribers location and potentially the contents of their phone calls to be obtained. The effect was that one of the affected MTS used tried to call someone else, their call would be forwarded to a physical land line number in St. Petersburg, Russia allowing the interception of the communication.

The Ukrainian regulator then assigned responsibility for the nodes that generated the SS7 based on the origination addresses in the SS7 packets received. Names, addresses, bank account details and medical data stolen due to a security vulnerability that could give hackers the access to their mobile devices.

Software from Ericsson misinterpreted this very rare signaling messages stopping parts of mobile traffic up. Ericsson identified how the misperception of signaling occurred and applied the necessary correction to fix the issue. The reality is that old and insecure protocols could harm our privacy dramatically enlarging our surface of attack.
