Cybersecurity Threats to eSIM

A critical vulnerability has been discovered in the GSMA TS.48 Generic Test Profile versions 6.0 and earlier, commonly used in the eSIM industry for radio compliance testing. This flaw enables attackers with physical access to an embedded Universal Integrated Circuit Card (eUICC) to exploit publicly known keys, allowing the installation of unverified and potentially malicious JavaCard applets.
