The Ledger research team has identified a vulnerability in the widely used Android smartphone processor chip, potentially putting Web3 users who rely on software wallets at risk of physical attacks. Ledger's Donjon team successfully bypassed core security checks and took full control of the Mediatek Dimensity 7300 chip through a hardware fault injection attack demonstration. Ledger emphasizes that even the most advanced smartphone chips are vulnerable to physical attacks, and relying solely on smartphone hot wallets to protect private keys poses risks. (TheBlock)
