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.
