Unpatchable Flaw in Smartphone Chip Exposes Devices to Electromagnetic Attacks

A recent discovery by Ledger’s Donjon lab has revealed a significant vulnerability in a widely used smartphone chip developed by MediaTek. The flaw, which resides in the chip’s boot ROM, can be exploited through precisely timed electromagnetic pulses, allowing attackers to gain full control of the device. This unpatchable flaw has significant implications for the security of smartphones and the blockchain ecosystem as a whole.

Key Findings

  • The vulnerable code sits in the chip’s boot ROM, making it impossible to correct with a software update.
  • The MediaTek Dimensity 7300 (MT6878) chip, found in many Android phones, is affected by this flaw.
  • By applying carefully timed electromagnetic pulses, researchers were able to bypass memory-access checks and escalate into EL3, the highest privilege level in the ARM architecture.
  • The success rate of the attack is estimated to be between 0.1%-1%, allowing for a full compromise within minutes under lab conditions.

Implications for Cryptocurrency Holders

The report comes at a time when attacks targeting Bitcoin (BTC) and other cryptocurrency holders are on the rise. According to a July report by Chainalysis, over $2.17 billion has been stolen from cryptocurrency services so far in 2025, exceeding the entirety of 2024. While physical attacks are growing, the majority of crypto-related thefts are still perpetrated by hackers through phishing attacks or scams.

Hardware vs. Software Wallets

The discovery highlights the importance of secure, tamper-resistant chips in hardware wallets. Ledger’s Donjon team notes that smartphones’ threat models cannot reasonably exclude hardware attacks, and security should ultimately rely on Secure Elements, especially for self-custody. In contrast, software wallets or "hot wallets" are apps that allow users to store their digital assets on various devices, leaving them vulnerable to hacks and phishing attacks.

Broader Market Implications

The news of this unpatchable flaw has significant implications for the broader market. As the use of smartphones for cryptocurrency transactions becomes more widespread, the risk of electromagnetic attacks poses a growing concern for retail investors. The fact that this flaw cannot be patched with a software update means that devices built on the affected chip will remain exposed, potentially leading to a surge in hardware-based attacks. This could lead to increased demand for secure hardware wallets and a shift towards more robust security measures in the cryptocurrency industry. As the market continues to evolve, it is essential for investors to stay informed about potential security risks and take necessary precautions to protect their assets.

In conclusion, the discovery of this unpatchable flaw in the MediaTek chip serves as a reminder of the importance of robust security measures in the cryptocurrency industry. As the market continues to grow and evolve, it is crucial for investors to stay vigilant and take necessary precautions to protect their assets from potential threats.
