What is the SS7 communication protocol?
The SS7 protocol, not a loophole, is a communications protocol developed in 1975 that is responsible for connecting and connecting local and international telecommunications companies. It is responsible for enabling roaming through your line and transferring the call from your local telecommunications service provider to your local telecommunications service provider. The international mobile subscriber identity is a 15-digit code generated with each line produced by the operators, which is generated as follows:
The first part of the figure is the Mobile country code or the country code and also the Mobile Network Code, which is the network code and the last code is generated through the network and is sent to the service providers in the rest of the world through your request to activate the roaming service on your line.
Initially, the SS7 protocol is called Short Message Service and Routing calls. It is also true for call forwarding and SMS. Any hacker can intercept and intercept this protocol, spy on text messaging services, listen to your voice calls, locate your location via the network location And telephone towers.
What is the weakness of the protocol?
In an article published in 2014 that through the SS7 protocol governments can intercept your calls and connections by 70%, but the system has been exploited to intercept text messages in the penetration of 2FA service or two-factor authentication or a system of verification via lines, which allows confirmation of ownership of your electronic accounts By sending a message confirming the ownership of the account with a text message on your phone, the information security professionals can intercept this activation message and penetrate your accounts in a simplified and easy way.
In fact, the networks have been using the protocol since 1980 until this moment and more than 800 service providers around the world are now operating and are now insecure because of their protection or encryption.
