Security researchers have uncovered significant vulnerabilities in Bambu Connect, an Electron-based 3D printer control application, highlighting potential security risks for users.
The investigation revealed that Bambu Connect relies heavily on "security through obscurity" principles, which experts consider an inherently weak security approach. The app's core functionality and sensitive data, including private keys and certificates, were found to be merely obfuscated rather than properly encrypted.
Through detailed analysis of the application's MacOS version, researchers discovered that the app uses asarmor protection, which can be bypassed using specific technical approaches. The investigation exposed how the app's encryption key could be extracted from the application files using reverse engineering tools like Ghidra.
The research team developed a Python-based solution that successfully decrypted the application's obfuscated strings, including private keys and certificates. This finding demonstrates that malicious actors could potentially access sensitive data stored within the application.
Industry experts recommend that Bambu Lab implement stronger security measures to protect user data. The current implementation raises concerns about the overall security architecture of the application and its potential impact on user privacy.
This discovery serves as a reminder to both developers and users about the importance of implementing robust security measures rather than relying on obscurity-based protection methods.
The findings have implications for both home users and professional environments where Bambu Connect is deployed for 3D printing operations. Users are advised to monitor future updates from Bambu Lab addressing these security concerns.
