#DecemberMarketOutlook Android Phone Users Beware: Security Vulnerability Detected for Cryptocurrencies!

Ledger analysts have identified a security vulnerability on Android phones equipped with a specific processor.
The Donjon research team from cryptocurrency security firm Ledger has discovered a critical security vulnerability in a smartphone processor widely used in the Android ecosystem.

The vulnerability puts digital assets at risk if devices using software-based Web3 wallets are physically compromised.
Ledger researchers found that with electromagnetic fault injection (EMFI), the secure boot process of the processor can be bypassed on the MediaTek Dimensity 7300 chip, manufactured by TSMC. According to the vulnerability, attackers can disable the earliest security checks in the device’s boot ROM and gain full control over the processor.

Using open-source tools, the team sent electromagnetic pulses to the chip at precise moments, gaining access to the boot ROM’s operational data. By bypassing the filtering mechanism in the chip’s write commands, they were able to alter the return address in the ROM stack. This method enabled arbitrary code execution at the processor’s highest privilege level, EL3. According to Ledger, the attack can be repeated in just a few minutes.

The company emphasized that this finding does not affect Ledger hardware wallets, arguing that “even the most advanced smartphone chips are vulnerable to physical attacks.” Ledger stated that smartphones used as hot wallets are not suitable environments for storing private keys, and true security can only be achieved with hardware wallets that contain secure elements.
