The cryptographic keys meant for testing were used in production devices by numerous manufacturers, compromising the integrity of Secure Boot protections across several major devices.
These non-production test keys, marked as 'DO NOT TRUST', acted as a root of trust for systems across the computing device industry, leading to significant vulnerabilities.
With the private key of one test key publicly available, hackers can exploit this weakness to install rootkits, effectively undermining security for critical devices like ATMs and voting machines.
The implications of using these insecure keys are enormous, as this affects not just consumer systems, but also critical infrastructure including medical devices and financial transaction systems.
