Omer Ninburg, CTO of Novee Security, joins us on this episode of Research Saturday to discuss their work on "From PDF to Pwn: Scalable 0day Discovery in PDF Engines and Services Using Multi-Agent LLMs." Historically, Portable Document Formats – the immutable, localized PDF – was once considered a “safe” component inside enterprise environments. That is no longer the case. To demonstrate how PDF services and engines can be exploited, the team at Novee used their proprietary, multi-agent LLM system to uncover vulnerability patterns, and systematically scale them into a broad discovery campaign across two PDF vendor ecosystems. The research uncovered 16 verified vulnerabilities across client-side PDF viewers, embedded plugins, and server-side PDF services. The research and executive brief can be found here: ⁠From PDF to Pwn: Scalable 0day Discovery in PDF Engines and Services Using Multi-Agent LLMs Hacker-Trained AI Discovers 16 New 0-Day Vulnerabilities in PDF Engines Learn more about your ad choices.
