Watch Out: Some Users’ Bitcoin and Altcoins Could Be in Danger, Vulnerability Detected in Chinese Chip – Here’s What You Need to Know

A newly discovered vulnerability in a widely used Chinese microcontroller puts billions of devices and the Bitcoin (BTC) stored on them at serious risk, according to cybersecurity researchers. Risky Chip Used in Numerous Bitcoin and Cryptocurrency Cold Wallets The vulnerability, officially cataloged as CVE-2025-27840, affects the ESP32 chip, a popular microcontroller found in a number of Internet of Things (IoT) devices, including hardware wallets used to store Bitcoin. Security experts warn that the flaw could allow hackers to remotely steal private keys or forge BTC transaction signatures, potentially giving users unauthorized access to their funds. The ESP32 chip is made by Chinese company Espressif Systems and is used in devices such as the Blockstream Jade wallet, which relies on the chip to generate cryptographic signatures for Bitcoin transactions. However, researchers found that the chip’s random number generator lacks sufficient entropy and is therefore vulnerable to brute force attacks that could reveal private keys.

A team of white-hat hackers demonstrated the practical seriousness of the problem by managing to decrypt the private key of an active Bitcoin wallet holding 10 BTC. Beyond the random number generator flaw, the chip’s update mechanism is also vulnerable. Hackers could use module updates to sign unauthorized transactions or inject malicious code, turning the chip into a covert access point for digital theft. With billions of ESP32 chips embedded in devices around the world, the scale of the threat is immense, especially for individuals and companies that rely on self-storage solutions for digital assets. Crypto Deep Tech and other researchers are currently working under responsible disclosure protocols, warning wallet manufacturers and developers while calling for urgent action. However, with the flawed chips already embedded in a large number of devices, experts warn that the path to securing the affected infrastructure will be complex and lengthy. For now, users of hardware wallets featuring ESP32 chips are advised to be on the lookout for firmware updates and follow the guidance of their wallet providers as security patches are developed. *This is not investment advice.
