eSIM security flaw
July 14, 2025
A major eSIM security flaw tied to outdated test profiles and a six-year-old Java Card bug could let attackers install malicious software, clone identities, or spy on users. Billions of devices are potentially at risk. Exploitation requires brief physical access but allows remote control afterward. Kigen and GSMA have issued patches and updated standards, but many devices may still be exposed.
