The attacker can use any mobile device, a server application that can send binary text messages, phone or cellular modem to initiate an attack. Simjacker’s potential for wreaking havoc is significant because it takes advantage of a system that was designed to make it easy to access SIM-enabled devices.

They can send executable code directly to SIM cards and retrieve sensitive data from devices. Over the past two years, hackers have refined their ability to exploit the vulnerability created by the channel. This data message may contain the device’s location and other information, which can be stored, reused or sold. When the information the hacker wants is retrieved, the victim’s device then sends the information to the hacker’s device via another SMS or a BIP session. The SIM card receives the Simjacker SMS attack message and then sends specific instructions to the browser by using scripts, requesting location information and other information specific to the device.

Simjacker attacks rely on a piece of software called the browser, which resides in the SIM card. The code instructs the device’s SIM card to take control of the device to access its data or execute commands. How Does a Simjacker Exploit Work?Ī Simjacker attack begins when a mobile device or a server sends an SMS message that contains a specific type of code to a mobile device or GSM modem. Based on publicly available information, at least 1 billion devices are affected.

Simjacker has been used by surveillance companies and some governments around the world, and these organizations may still be using the exploit today. It can run on most 2G (GSM), 3G (UMTS), 4G (LTE) and even 5G devices.

Simjacker has been used against iPhones, Android phones and SIM-equipped Internet of Things (IoT) devices.

It’s important to note that all makes and models of cellular devices are vulnerable if the SIM card has the old technology installed on it, which is very common. Anecdotal evidence suggests that Simjacker has been used in approximately 30 countries over the past two years. Moreover, some governments have used Simjacker, and they don’t reveal this information. The ecosystem is very fragmented with many mobile operators worldwide, so it isn’t easy to compile an accurate estimate. However, statistics on how much damage has resulted from Simjacker attacks are hard to come by. Which Devices are Vulnerable?Ī broad attack surface exists because numerous carriers and SIM vendors around the world adopted the add-on technology. This blog provides an overview of the problem and directs you to additional resources that can help you protect your devices. However, if your IoT deployments have SIM cards from other sources, you may need to act. If you’re already a Telit Connectivity customer, you have nothing to worry about: Your SIM cards are safe. Telit Connectivity Solutions customers are protected from Simjacker attacks on their IoT devices.

Unfortunately, it also created the back door into the component. The add-on technology helped mobile carriers and SIM vendors create value-add services to monetize their SIM cards. The SIM toolkit is an environment that allows developers to leverage the capabilities of the SIM card to build applications. The problem is rooted in an old piece of technology built on top of the SIM toolkit standard. Malicious actors and government agencies use Simjacker attacks to eavesdrop, track movement, extract data and more - all without leaving a trace. These exploits, known as Simjacker attacks, take advantage of a common back door into the SIM card.
