⚠️ Security Alert: Some Android devices equipped with the MediaTek 7300 SoC have been found to be vulnerable to USB injection attacks. Once an attacker obtains the device, even if it is powered off, they can still extract the encryption key, unlock the storage space, and ultimately obtain the seed phrase stored in the software wallet within approximately 45 seconds. If you're used to keeping large sums of money in your mobile hot wallet, you should be aware of these risks. Many people underestimate the threat of physical contact attacks. Mobile phone chips are primarily designed for general-purpose computing, not specifically for private key security. Simple suggestion: 🔹 Keep large or long-term assets in a hardware wallet (with private key isolation via a secure chip). 🔹 Update the system promptly and try to prevent the device from falling into the hands of strangers.
