Overview of SS7
The Signaling System 7 (SS7) is a set of telecommunication signaling protocols that are used globally to control the setup, maintenance, and tear down of calls in Public Switched Telephone Networks (PSTNs). It is a vital component of phone networks, enabling the seamless routing of calls and messages between different network operators. SS7 plays a crucial role in ensuring the interoperability of telephone networks, allowing users to connect and communicate with each other regardless of their service provider.
What is SS7?
SS7, also known as C7 in Europe, is a suite of protocols that defines the exchange of information and flow control between network elements such as switches, databases, and signaling transfer points (STPs). It operates at the network layer of the OSI model and provides the means for signaling and control functions in a phone network. SS7 is responsible for functions such as call setup and teardown, call routing, and advanced features like call forwarding and roaming.
How does SS7 work?
SS7 operates on a separate network dedicated solely to signaling traffic. It uses out-of-band signaling, which means that it carries the control and signaling information on a separate network parallel to the voice or data traffic. SS7 messages travel over dedicated signaling links, separate from the voice or data channels, to efficiently handle call setup and other signaling functions.
When a call is initiated, SS7 signaling messages are exchanged between the originating and terminating switches to establish and maintain the call. SS7 protocols ensure the delivery of these messages and handle functions such as addressing routing, and error detection. The network elements involved in the call, such as switches and databases, use the SS7 protocols to communicate with each other and coordinate the call setup process.
Purpose of SS7 in phone networks
The primary purpose of SS7 in phone networks is to enable reliable and efficient call routing and control. By using SS7, network operators can establish and maintain calls, handle advanced features like call forwarding and roaming, and provide seamless connectivity for their subscribers.
SS7 protocols are designed to facilitate rapid call setup and teardown, allowing users to establish connections in a matter of seconds. It enables features such as caller identification, call waiting, call forwarding, and three-way calling. Additionally, SS7 is also used for services like Short Message Service (SMS), which allows the exchange of text messages between mobile devices.
Overall, SS7 is a critical component of modern telephony systems, ensuring the smooth operation of phone networks and the services they provide.
Vulnerabilities in SS7
While SS7 is essential for the functioning of phone networks, it is not without vulnerabilities. These vulnerabilities can be exploited by malicious actors to gain unauthorized access, intercept communications, and compromise the security and privacy of users.
Exploiting SS7 for unauthorized access
One of the main vulnerabilities in SS7 is its lack of authentication and encryption mechanisms. SS7 was developed in an era when security concerns were not as prevalent as they are today. As a result, many of the SS7 protocols do not provide sufficient mechanisms to verify the identity of signaling messages or encrypt the information they carry.
This makes it possible for attackers to intercept and manipulate signaling messages, allowing them to gain unauthorized access to the network.
Common vulnerabilities in SS7
Several vulnerabilities exist within the SS7 protocol that can be exploited. One notable vulnerability is related to the handling of global titles, which are used to identify network elements. Attackers can manipulate these global titles to redirect calls or messages to their own malicious devices. Additionally, weaknesses in the procedure for assigning temporary identities to mobile devices can also be exploited to perform fraudulent activities.
Signaling System 7 (SS7) protocol weaknesses
The SS7 protocol suffers from various weaknesses that expose it to potential exploitation. One such weakness is the lack of end-to-end security. While SS7 provides security mechanisms for signaling traffic between network elements, it does not guarantee end-to-end security for user communications. This allows attackers to intercept and manipulate user communications at network nodes where signaling messages are processed.
Another weakness is the reliance on trust between network operators. SS7 assumes that operators will accurately validate and propagate signaling messages, but this trust can be abused by malicious actors who gain unauthorized access to the network.

Gaining Control with SS7 Hacking
SS7 hacking refers to the act of exploiting vulnerabilities in the SS7 protocol to gain control over phone networks and the devices connected to them. This enables attackers to perform various malicious activities, compromising the security and privacy of users.
Understanding SS7 hacking
SS7 hacking involves exploiting the weaknesses in the SS7 protocols to gain control over the signaling traffic within a phone network. By intercepting and manipulating signaling messages, attackers can perform actions such as call and message redirection, eavesdropping on communications, and locating mobile devices.
Targeting a phone number
To gain control over a specific phone number, an attacker would need to identify vulnerabilities in the SS7 network that the number is connected to. By exploiting these vulnerabilities, the attacker can intercept the signaling messages related to the targeted phone number and manipulate them to their advantage.
Intercepting SMS messages
One of the common methods of SS7 hacking is intercepting SMS messages. By exploiting SS7 vulnerabilities, attackers can intercept the signaling messages that carry SMS communications. This gives them access to the content of the messages, allowing for unauthorized surveillance or theft of sensitive information.
Locating a mobile device
Through SS7 hacking, attackers can also locate a mobile device connected to the network. By intercepting signaling messages related to the device’s location, an attacker can track the movements of the device and potentially gain valuable information about the device’s owner.
Call and message redirection
SS7 hacking allows attackers to redirect calls and messages to other numbers or devices. By manipulating the signaling messages, they can reroute calls or messages to a destination of their choosing, potentially enabling them to eavesdrop on conversations or obtain sensitive information.
Remote eavesdropping
Another significant risk of SS7 hacking is the ability to remotely eavesdrop on phone calls. By intercepting the signaling messages that establish and maintain calls, attackers can gain access to the audio streams and listen in on conversations in real-time.
Methods to Exploit SS7
Various methods can be employed to exploit the vulnerabilities in the SS7 protocol and carry out hacking activities.
Spoofing a user’s identity
One method involves spoofing a user’s identity using SS7 vulnerabilities. By intercepting the signaling messages that handle identification and authentication, attackers can impersonate a legitimate user and gain unauthorized access to the network.
Obtaining Temporary Mobile Subscriber Identity (TMSI)
Attackers can exploit weaknesses in the process of assigning temporary identities to mobile devices. By intercepting the signaling messages that carry these identities, they can obtain the Temporary Mobile Subscriber Identity (TMSI) of a target device. This can be used to track the device’s movements or perform other malicious activities.
Duplicating SIM cards
Another method involves duplicating SIM cards using SS7 vulnerabilities. By intercepting the signaling messages related to SIM card authentication and encryption, attackers can clone a target device’s SIM card. This allows them to gain access to the device owner’s account, eavesdrop on communications, or carry out fraudulent activities.
SIM card cloning
Attackers can exploit SS7 vulnerabilities to clone SIM cards, enabling them to take over the identity of a target device. By intercepting the signaling messages that handle SIM card authentication, they can extract the necessary information to create a duplicate SIM card. This can grant them access to the target device’s account, allowing for unauthorized actions and surveillance.
