Key Leaks, Vault Failures, and TEE Attacks: Highlights from RWC 2026

Highlights from RWC 2026 summarize research showing systematic leakage of private keys (945,560 keys mapped to 139,767 certificates), multiple critical vulnerabilities in cloud password managers (27 attacks enabling master-key recovery or password leaks), and demonstrations of Trusted Execution Environment (TEE) attacks via memory-bus interposition that can extract keys; the article emphasizes fragility in PKI and secret management and the need for stronger protections for non-human identities.
