I published a threat model for a SeedSigner on a Nintendo DSi. Tear it apart.

The article announces the publication of a detailed threat model specifically developed for a SeedSigner device implemented on a Nintendo DSi. A SeedSigner is an open-source, air-gapped hardware signing device widely utilized by Bitcoin users for enhanced security and self-custody of their funds. By repurposing a Nintendo DSi, a common consumer electronic device, the project exemplifies the innovative approaches within the Bitcoin community to create cost-effective and secure signing solutions. The core purpose of a threat model is to systematically identify and analyze potential vulnerabilities, attack vectors, and risks inherent in a system. For a SeedSigner on a DSi, this would involve examining potential weaknesses ranging from supply chain attacks on components, software exploits specific to the DSi's architecture, and physical tampering attempts, to operational security risks. The invitation to "tear it apart" signals a call for peer review and community auditing, a crucial practice in open-source security projects to identify unforeseen flaws and harden the overall resilience of the device against real-world threats. This collaborative scrutiny aims to ensure the highest possible standard of security for users employing this DIY Bitcoin signing solution.
