According to ChainCatcher, Ledger's Donjon research team has demonstrated that electromagnetic fault injection (EMFI) can completely compromise a commonly used Mediatek smartphone chip, which is found in many Android phone models. This issue requires attackers to have physical access to the device, highlighting the risks faced by users storing private keys on smartphones. Ledger stated that its team examined the Mediatek Dimensity 7300 (MT6878) chip produced by TSMC. Researchers used EMFI tools to disrupt the chip's boot ROM, successfully bypassing core security checks and gaining full control of the chip, allowing arbitrary code execution at the highest privilege level (EL3)
