Summary

Researchers found that 0.75% of TLS certificates and 1.70% of additional certificates may be vulnerable due to insufficient entropy during key generation. They were able to obtain RSA private keys for 0.50% of TLS hosts and 0.03% of SSH hosts, and DSA private keys for 1.03% of SSH hosts, due to entropy problems. The vulnerable hosts were mostly headless or embedded devices, such as routers and firewalls, which generate keys automatically on first boot with limited entropy sources. The problems were caused by specific defective implementations that generate keys without sufficient entropy, and the researchers identified vulnerable devices and software from dozens of manufacturers. They recommend action by developers, device manufacturers, and users to mitigate these problems and created an online key-check service to test whether keys are vulnerable.
