Ledger Warns: Chip Used in Solana Phones Exposed to ‘Unstoppable’ Security Flaw
Ledger security experts have a serious, unfixable flaw in the MediaTek Dimensity 7300 chip, which powers smartphones like the crypto-focused Solana viewker. With physical access, attackers can use electromagnetic fault injection during the boot process to bypass all defenses, take complete control of the device, and access
A from Wednesday discusses a hardware-level flaw that makes mobile crypto wallets running on these processors more risky.
Targets of Vulnerability: Boot Process
Charles Christen and Léo Benito led Ledger’s Donjon team, which began investigating the exploit in February and finished by ahead May.
They used electromagnetic pulses to disrupt the chip’s initial beginup phase, change security settings, and bypass memory protections so that they could have “full and absolute control” of the gadget.
They said that the success rates for each effort range from 0.1% to 1%, but that repeated in quick succession might breach defenses within minutes.
MediaTek Talks About Chip Limits
MediaTek said the difficulty is not with the design of the Dimensity 7300, which is meant for consumer cellphones rather than high-security applications like hardware wallets.
The business told Ledger, “For products that handle sensitive information, manufacturers should put in place specific protections against physical attacks.” Vendors affected were notified, but there is no software patch because the difficulty is at the semiconductor level.
What This Means For Solana viewker and Crypto Users
The Solana viewker, billed as a gateway, is one of many mid-range 5G phones with this chip, making it easier for thieves to steal local Secret keys.
Ledger stressed that any device with the Dimensity 7300 that stores crypto keys is at the identical risk, since the attack affects the boot sequence on all devices. standards call for more physical security, which makes managing assets on a device more dangerous.
More Warnings About Mobile Security
Experts say that sophisticated system-on-chips, like the Dimensity 7300 launched in June 2024, still have significant difficultys that affect crypto holders in the real world. Ledger tells manufacturers to provide additional layers of protection for sensitive processes beyond what chips can provide.
As physical attacks become more advanced, users should not store critical Secret keys on phones that are simple to hack. Instead, they should use dedicated secure devices.
