XMPP Stanza Smuggling or How I Hacked Zoom

Explore a groundbreaking security vulnerability in XMPP-based applications through this 36-minute Black Hat conference talk. Delve into the concept of XMPP stanza smuggling, a novel attack vector targeting XMPP client software. Discover how subtle XML parsing quirks can be exploited to inject attacker-controlled XMPP control messages into victim clients, and understand why the XMPP protocol's design makes it particularly vulnerable to such attacks. Learn how this technique led to a zero-click remote code execution vulnerability in the Zoom client. Presented by Ivan Fratric, this talk provides valuable insights for security professionals, developers, and anyone interested in messaging protocol security.
