What is SS7?
The SS7 protocol, also known as Signaling System No. 7, is a set of signaling protocols used in telecommunications networks to enable the exchange of information between network elements. It provides the necessary signaling for call setup, routing, and control in both fixed and mobile networks.
One of the key features of the SS7 protocol is its ability to support advanced signaling capabilities, including the delivery of short messages (SMS), caller ID, call forwarding, and call waiting. It also enables the implementation of more complex services like mobile number portability and mobile banking.
What are SS7 Attacks?
SS7 attacks, also known as Signaling System 7 attacks, are a type of telecommunication security threat that exploit vulnerabilities in the SS7 protocol. The SS7 protocol is a set of signaling protocols used to establish and manage telephone calls and text messages between different networks.
These attacks can have serious implications, as they allow hackers to intercept, manipulate, and redirect telecommunications traffic. This means that attackers can eavesdrop on phone calls, read text messages, and even track the location of targeted individuals.
Types of SS7 Attacks
One common type of SS7 attack is known as a “man-in-the-middle” attack. In this scenario, the attacker intercepts the communication between two parties and can then either passively listen to the conversation or actively manipulate the content of the communication. This can be particularly concerning when it comes to sensitive information, such as banking details or personal conversations.
Another type of SS7 attack is known as a “location tracking” attack. By exploiting vulnerabilities in the SS7 protocol, attackers can track the location of a targeted individual, even without their consent. This can pose a significant threat to personal privacy and security.
