eSIM hack allows for cloning, spying 

Research focusing on eSIM security has led to the discovery of a hacking method that could have serious implications.

Embedded SIMs, or eSIMs, have become increasingly common. They eliminate the need for physical SIM cards in mobile phones and other IoT devices that require cellular communications. One important component of the eSIM ecosystem is the embedded Universal Integrated Circuit Card (eUICC), which enables remote SIM provisioning and the use of multiple profiles for connecting to different mobile networks. 

Security Explorations, the research lab of Poland-based AG Security Research, has conducted an extensive analysis of eSIMs and eUICC and found vulnerabilities that could be exploited to clone a target’s eSIM and spy on their mobile communications.
