Researchers Discover MediaTek Chip Vulnerability That Could Impact Millions of Android Phones
Ledger Donjon, a group of security researchers for the cryptocurrency wallet firm Ledger, claimed to have discovered a vulnerability that potentially affects millions of Android phones powered by MediaTek chipsets. Ledger’s Chief Technology Officer (CTO) Charles Guillemet claims that the security researchers used the CMF Phone 1 to discover the MediaTek vulnerability. The company executive claims that they were able to breach the phone’s foundational security within 45 seconds using a laptop. MediaTek Dimensity and Helio chipsets use Trustonic’s Trusted Execution Environment (TEE) to protect sensitive data on phones.
