Vulnerability in MediaTek Chips Could Impact 25% Android Smartphones Security researchers at Ledger’s Donjon team uncovered a boot‑chain vulnerability in certain MediaTek Android chipsets using Trustonic’s Trusted Execution Environment that could expose encryption keys and wallet seed phrases on roughly 25% of Android phones. They demonstrated an attack that, with brief physical USB access and no malware, recovered PINs and...

Security researchers found a boot-chain flaw in MediaTek chips using Trustonic TEE that lets attackers extract PINs and wallet seeds with brief USB access on 25% of Android devices. Fix available from OEMs. #MediaTek #TrustedExecution #India
