eSIM and its security and privacy issues: Embedded Subscriber Identity Module in a nutshell ☎️ 🐾🔎🌍🎯

Security researchers Maryam Motallebighomi, Jason Veara, Evangelos Bitsikas, and Aanjhan Ranganathan presented their comprehensive review of eSIM technology last month, and discussed the security and privacy issues it has.

Some gems from the paper:

💎 Starting an eSIM business is easier than starting a coffee shop.

💎 eSIMs can act like mini spyware - silently pinging servers or downloading hidden SMS messages.

💎 Travel eSIMs offer convenience but also come with hidden data routing, opaque resellers, and potential surveillance risks.

Very interesting and practical for many. Please enjoy the read and share it with your peers and friends.

Thank you.
