Recently, the StarkWare ecosystem manager made significant announcements through the X platform, pointing out multiple security vulnerabilities and design problems in the Fractal Bitcoin project that may endanger user assets. The specific issues include: 1. **RPC Credential Security**: Fractal Bitcoin's RPC credentials are hardcoded and cannot be configured via environment variables, making them susceptible to leakage. Moreover, publicly exposed RPC servers increase the risk of malicious attacks. 2. **Access Permissions for IP Addresses**: Any IP address can connect to the RPC server, meaning that user nodes may face potential attacks from anywhere globally, significantly increasing the possibility of system breaches. 3. **ZeroMQ Connection Security**: Some settings allow any IP address to establish ZeroMQ connections, leading to security vulnerabilities. Additionally, if the limit on connection cancellations is removed, the system may be exhausted by too many requests. 4. **Organization and Repository Management**: There are deficiencies in managing the official GitHub organization or repository, making it difficult to track and manage project documentation and code changes, affecting overall security and maintainability. In conclusion, Fractal Bitcoin has obvious security issues and design flaws in multiple areas, suggesting that developers and users should pay close attention and take corresponding measures to fix them to safeguard their assets.
