Practically-Exploitable Cryptographic Vulnerabilities in Matrix

Explore critical cryptographic vulnerabilities in the Matrix standard for federated realtime communication and its flagship client, Element, in this 34-minute Black Hat conference talk. Delve into how these flaws compromise confidentiality and authentication guarantees against malicious servers, despite the use of well-known cryptographic building blocks. Learn from security experts Martin Albrecht, Sofía Celi, Benjamin Dowling, and Dan Jones as they present their findings and discuss the implications for Matrix's security claims.
