eSIMpocalypse: Kigen eUICC Hack Shatters Security Myths
Security Explorations has cracked the supposedly uncrackable Kigen eUICC, proving that eSIM security is as watertight as a colander. Despite prior dismissal, their 2019 Java Card vulnerabilities have now been validated. This hack places eSIM security risks in the spotlight—time to rethink those “tamper-proof” claims!

Hot Take:
***Who knew that a tiny chip, once thought of as secure as a bank vault, is now as exposed as your grandma’s Facebook password? The Kigen eUICC eSIM security has been cracked, and it’s a situation that demands your attention – unless you want your phone to play an unwelcome duet with a hacker.***
Key Points:
– Researchers cracked the Kigen eUICC card, exposing vulnerabilities in eSIM security.
– The hack demonstrates that eSIMs aren’t as secure as traditional SIM cards, despite claims.
– The compromise was achieved through physical access and key knowledge, but OTA vectors can’t be ruled out.
– This is the first public hack against consumer GSMA eUICC and Kigen eSIM.
– The research highlights the need for enhanced eSIM security awareness among MNOs and vendors.
