Special Segment: The Breaches That Defined a Decade

Timestamps: [12:43] – [23:52]
Guests: Maria Varmazes & Dave Bittner

Theme

A 10-year retrospective on the cyber breaches that have most influenced industry practices, mindsets, and policy directions.

Key Breaches Explored

Sony Pictures Hack (2014)

• "It grabbed a lot of people's attention that a big major brand could get hit this way. And sort of, I think, set the global stage for these large scale breaches." – Dave ([13:52])
• Emblematic of the fusion between geopolitics, media, and corporate security.
• Notoriously linked to North Korea and the release of "The Interview" movie.

US OPM Breach (2015)

• "This was a major breach of all kinds of information...including things about people's security clearances. So some of our nation's greatest secrets were revealed.” – Dave ([15:08])
• Contributing Factors: Outdated equipment, neglected protocols.
• Set precedent for accountability and highlighted national security implications.

WannaCry and NotPetya (2017)

• “Showed global disruption, where shipping companies got affected and systems were actually shut down.” – Dave ([16:34])
• Proved that ransomware/wipers can have worldwide, physical supply chain impacts.

Equifax Breach (2017)

• “Still dealing with the fallout from that one to this day.” – Maria ([17:11])
• Impact: Massive personal data exposure; ongoing consequences for consumers and regulations.

SolarWinds Supply Chain Attack (2020)

• “That was really the one that put a big red star on supply chains and third party providers.” – Dave ([17:24])
• Sparked conversation about CISO legal liabilities, personal accountability, and software supply chain risks.
• “...The CISO was in jeopardy of legal criminal charges.” – Dave ([17:50])

Trends and Reflections

Convergence of Threat Actor Motivations

• “You'll see perhaps state actors, state sponsored actors who are doing a little side work, who are out there getting some money, and the nation states are willing to look the other way, allow them to supplement their incomes...” – Dave ([19:53])
• Financial crime and espionage increasingly intersect; boundaries blur.

Industry Mindset: Acceptance and Empathy

• “When you go through the stages of grief and land at accept, I'm kind of there. ...I try to remind myself to maintain my empathy and my sympathy for the folks that this happens to.” – Dave ([21:09])
• Critique of "smug superiority" in infosec, emphasis on community, continual learning, and realistic approaches.

Hope Amid Challenges

• “You see the people who are out there doing the good work, who are innovating, who are, as I said, in good faith, trying to make this world a little bit safer ...and all of those things I find uplifting and they do give me hope.” – Dave ([22:43])

Notable Quotes and Moments

• “Retrospective negligence...” – Dave ([15:05]) (on outdated protocols contributing to OPM breach)
• “It can get you down. You can feel like I'll joke sometimes that, 'Hi, I'm Dave Bittner, and here's today's bad news.' But on the other hand, you see the people who are out there doing the good work...” – Dave ([22:43])
• "I try to remind myself to maintain my empathy and my sympathy for the folks that this happens to...I have no time or patience for [smug superiority] because I don't think it's helpful.” – Dave ([21:09])

Other Security Stories and Closing Notes

AFC Ajax Breach (Sports Case Study)

• Timestamps: [26:23] – [27:41]
• Suspected underreporting of exposure—API flaws allowed impersonation, ticket theft, stadium ban evasion.
• “...the ability to manipulate accounts as well as access data points to a deeper breakdown—less a contained breach and more a system that left the door wide open and the playbook sitting right next to it.” – Maria ([27:22])
