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2015 OPM breach, which exposed sensitive security-clearance data and was attributed to long-term access by China amid outdated government systems and security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.
