The vulnerability affects various SIM card types, making a wide range of users potential victims.
Simjacker Overview
Simjacker, a sophisticated mobile security vulnerability, allowed attackers to remotely control mobile phones without user interaction, essentially turning them into surveillance devices. This wasn’t achieved through a simple app or malware download; it exploited a far deeper, more fundamental weakness in the mobile network infrastructure.Simjacker leverages vulnerabilities within the SS7 (Signaling System No. 7) protocol, the backbone of global telecommunications.
SS7, while crucial for connecting calls and text messages, contains inherent security flaws that Simjacker ruthlessly exploited. Instead of directly targeting the phone’s operating system or applications, Simjacker manipulated SS7 signaling to send malicious commands directly to the SIM card itself. This bypassed traditional security measures focused on the phone’s software.
Simjacker’s Mechanism
The core of Simjacker’s attack lies in its ability to send malicious commands to a victim’s SIM card using SS7. These commands, crafted specifically to exploit weaknesses in the SIM card’s firmware, could trigger a range of actions, from retrieving location data to intercepting calls and messages. Crucially, the victim remained completely unaware of the attack. The attacker didn’t need access to the phone itself or even the phone number; only access to the SS7 network was required.
This highlights the critical need for enhanced security measures within the SS7 protocol itself, as well as robust SIM card firmware.
Susceptible SIM Cards
A wide range of SIM cards were vulnerable to Simjacker attacks. The vulnerability wasn’t tied to a specific manufacturer or operating system. Instead, it exploited weaknesses in the SIM card’s firmware, which is the low-level software that controls the SIM card’s functionality. Older SIM cards, lacking robust security features, were particularly susceptible. Even modern SIM cards, depending on their firmware version and security implementations, could potentially be vulnerable.
The attack targeted the SIM card’s ability to process commands from the network, making almost any SIM card potentially vulnerable, depending on its security level and how it handled incoming SS7 messages.
Stages of a Simjacker Attack
A Simjacker attack typically unfolds in several stages. First, the attacker gains unauthorized access to the SS7 network. This access could be achieved through various means, potentially exploiting vulnerabilities within the network infrastructure itself. Second, the attacker identifies a target SIM card. Third, the attacker crafts and sends malicious commands to the target SIM card via the SS7 network.
These commands are designed to exploit vulnerabilities in the SIM card’s firmware. Fourth, the SIM card executes these malicious commands, unknowingly providing the attacker with access to the victim’s data and communication capabilities. Finally, the attacker collects the desired information or carries out the intended actions, such as location tracking or call interception, often without leaving any trace on the victim’s device.

This section delves into the specific protocols exploited, the steps involved in an attack, the types of actions possible, and the necessary network infrastructure.
SS7 Signaling Protocols Exploited by Simjacker
Simjacker cleverly exploited several SS7 (Signaling System No. 7) messages, specifically focusing on those designed for legitimate mobile network operations. These include the “Send SMS” and “Read SMS” messages, but also more subtly, the “Mobile Equipment Identity” (IMEI) request and “Location Information” messages. By manipulating these messages, the attackers could surreptitiously interact with a victim’s SIM card without their knowledge or consent.
The attack hinges on the fact that SS7, while powerful, lacks robust authentication and authorization mechanisms in many implementations, allowing malicious actors to inject commands and receive sensitive data.
Technical Steps Involved in a Simjacker Attack
A Simjacker attack unfolds in several stages. First, the attacker identifies a target and obtains their IMSI (International Mobile Subscriber Identity). Next, they use this IMSI to interact with the SS7 network, exploiting vulnerabilities to send malicious commands to the victim’s SIM card. These commands, typically crafted as seemingly legitimate SS7 messages, instruct the SIM card to execute specific actions.
Finally, the attacker receives the response from the SIM card, potentially containing sensitive information or confirming successful command execution. The entire process happens without the victim’s knowledge or interaction.
Types of Actions Executed Remotely via Simjacker
The range of actions remotely executable through Simjacker is disturbingly broad. This includes the ability to surreptitiously read SMS messages, potentially revealing sensitive information such as one-time passwords (OTPs) for banking or other services. Furthermore, Simjacker can remotely retrieve the victim’s location data, allowing for real-time tracking. Critically, the attacker can also execute commands that could potentially lead to the installation of malware or compromise the victim’s device, offering a potential springboard for more intrusive attacks.
Network Infrastructure Required for a Simjacker Attack
A successful Simjacker attack requires access to the SS7 network. This typically involves compromising or leveraging weaknesses within a telecommunications provider’s infrastructure or through partnerships with malicious actors who possess such access. The attacker needs to be able to send and receive SS7 messages to and from the victim’s mobile network operator. This isn’t easily achieved, highlighting the sophistication and specialized knowledge required for this type of attack.
It also emphasizes the systemic vulnerabilities within the global telecommunications network.
Diagram Illustrating the Flow of a Simjacker Attack
Imagine a diagram showing three main sections: The Attacker, the Mobile Network, and the Victim.The Attacker’s section shows a computer connected to a server. This server is connected to a gateway which has access to the SS7 network.The Mobile Network section displays various interconnected nodes representing elements of the mobile network infrastructure, including the Home Location Register (HLR), the Visitor Location Register (VLR), and the Mobile Switching Center (MSC).The Victim section depicts a smartphone with a SIM card.The attack flow is as follows: The attacker sends malicious SS7 messages (e.g., “Send SMS” or “Read SMS”) via their server and gateway to the SS7 network.
These messages are routed through the MSC and VLR to the victim’s SIM card. The SIM card executes the commands, sending the requested data (e.g., SMS content, location data) back through the network to the attacker’s server. The entire process is covert, occurring outside the awareness of the victim and their mobile operator. The diagram visually emphasizes the attacker’s ability to bypass typical security measures by directly interacting with the SIM card via the vulnerable SS7 network.
