The Signalling System 7 (SS7) is a set of protocols used to support the telecommunication network in the world. It is a communications protocol that is used to coordinate the exchange of information among different parts of the telecommunications network. It is also known as Common Channel Signalling System 7 or Common Channel Interoffice Signalling 7. It is a set of protocols used for communication in the integrated services digital network (ISDN) and other public switched telephone networks. SS7 is responsible for controlling the routing of telephone calls and texts, the database of mobile subscribers, and the forwarding of messages between mobile phone networks. It is the basis for mobile phone switching, roaming, and other features used by today's phone networks. Due to its importance and ubiquitous nature, the security of SS7 has become a topic of great concern. This is because it is vulnerable to various types of attacks, some of which have been used to exploit its weaknesses. In this article, we will discuss the security flaws in SS7 and how they can be exploited. Overview of SS7 Security Flaws Security flaws in SS7 can be divided into two main categories: passive and active. A passive attack consists of an attacker passively monitoring the communication between two systems, such as the signaling messages that are exchanged between the signaling points of the telephone networks. By monitoring the traffic, an attacker can gain access to private data and track the movements of individuals. An active attack involves an attacker actively sending messages to the network, such as malicious messages that can disrupt or manipulate the communication between two systems. The security flaws in SS7 are particularly concerning due to the nature of the protocol. It is based on trust, meaning that it does not require authentication or encryption. This makes it vulnerable to man-in-the-middle attacks, spoofing, and other forms of manipulation. SS7 is also vulnerable to various types of attacks, such as denial of service, traffic analysis, spoofing, and unauthorized access. These attacks can be used to intercept calls, manipulate call charges, and spy on users. The vulnerability of SS7 has been demonstrated in a number of real-world attacks, including the “Pool Attack” against a mobile network in the Netherlands and the “Macho Man” attack against a Spanish mobile network. In both cases, attackers were able to intercept calls and extract sensitive information. The lack of authentication and encryption makes SS7 vulnerable to attacks and the security flaws in the protocol have been exploited by malicious actors for many years. What Makes SS7 Security Vulnerable? The primary reason for SS7 security vulnerabilities is the lack of authentication and encryption. In SS7, messages are not authenticated or encrypted, which means that an attacker can send a message with any content and it will be accepted by the receiving node. This makes it possible for an attacker to intercept, manipulate or read messages between two nodes. In addition, SS7 does not use strong encryption algorithms, making it easier for an attacker to intercept and decrypt messages. The lack of authentication also makes it possible for an attacker to spoof messages, as they can send a message as if it were from a legitimate source. This makes it possible for an attacker to send malicious messages to a target without being detected. How to Mitigate SS7 Security Flaws The first step to mitigating security flaws in SS7 is to ensure the use of authentication and encryption. Authentication ensures that messages are only accepted from legitimate sources, while encryption ensures that messages cannot be read by an attacker. It is also important to ensure that encryption algorithms used by the protocol are strong and can resist brute-force attacks. In addition, it is important to ensure that all devices that use SS7 are kept up to date with the latest security patches. This will ensure that any security flaws in the protocol are patched as quickly as possible. The security flaws in SS7 are a major concern for the security of mobile networks and communications. The lack of authentication and encryption makes it vulnerable to a range of attacks, which can be used to intercept calls, manipulate call charges, and spy on users. To mitigate these security flaws, it is important to ensure the use of authentication and encryption, as well as to keep all devices that use SS7 up to date with the latest security patches. By taking these steps, organizations can ensure that their networks and communications are secure.
