CyberWire Daily at 10: The breaches we still talk about. [Special Edition] Mar 29, 2026

Show notes

In this special edition of CyberWire Daily’s 10th anniversary series, N2K CyberWire's Maria Varmazis and Dave Bittner discuss the biggest breaches over the past 10 years.

The foundational 2014 Sony hack kicks off our conversation, then Maria and Dave highlight:

the 2015 OPM breach, which exposed sensitive security-clearance data and was attributed to long-term access by China amid outdated government systems and security
2017’s WannaCry and NotPetya's global disruption and Equifax's ongoing fallout
the 2020 SolarWinds breach underscored supply-chain risks and raised concerns about potential personal criminal liability for CISOs.

The conversation illustrates two main threat-actor categories—nation-state espionage and financially motivated criminals—and the increasingly blurred lines between them. Join us as we reflect on how the industry and cybercrime have evolved over the past decade.

When “safe” documents aren’t. [Research Saturday] Mar 28, 2026

Show notes

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:
