Remember the Simjacker vulnerability? Earlier this month, we reported about a critical unpatched weakness in a wide range of SIM cards, which an unnamed surveillance company has actively been exploiting in the wild to remotely compromise targeted mobile phones just by sending a specially crafted SMS to their phone numbers. If you can recall, the Simjacker vulnerability resides in a dynamic SIM toolkit, called the S@T Browser , which comes installed on a variety of SIM cards, including eSIM, provided by mobile operators in at least 30 countries. Now, it turns out that the S@T Browser is not the only dynamic SIM toolkit that contains the Simjacker issue which can be exploited remotely from any part of the world without any authorization—regardless of which handsets or mobile operating systems victims are using.

Cybersecurity researchers today revealed the existence of a new and previously undetected critical vulnerability in SIM cards that could allow remote attackers to compromise targeted mobile phones and spy on victims just by sending an SMS. Dubbed " SimJacker ," the vulnerability resides in a particular piece of software, called the S@T Browser (a dynamic SIM toolkit), embedded on most SIM cards that is widely being used by mobile operators in at least 30 countries and can be exploited regardless of which handsets victims are using. What's worrisome? A specific private company that works with governments is actively exploiting the SimJacker vulnerability from at least the last two years to conduct targeted surveillance on mobile phone users across several countries. S@T Browser , short for SIMalliance Toolbox Browser, is an application that comes installed on a variety of SIM cards, including eSIM, as part of SIM Tool Kit (STK) and has been designed to let mobile
