Ledger's research team has identified a critical vulnerability in a specific chip used in Android devices that could allow attackers to gain full control over the hardware. This flaw poses a significant risk to smartphone-based web3 wallets, as it enables potential physical attacks that could compromise private keys and funds stored on the device. The vulnerability facilitates a "full device takeover," highlighting the persistent security challenges facing mobile-based crypto storage solutions compared to dedicated hardware wallets. The researchers have flagged this issue to draw attention to the potential vectors for physical exploitation of consumer electronics holding digital assets.
