Nationstate Cybersecurity, Eric O’Neill’s Journey

Host: Dr. Darren Pulsipher
Guest: Eric O’Neill, former FBI Counterintelligence Operative, Author
Date: February 5, 2026

Episode Overview

This episode delves into the escalating threat landscape of nation-state cyber attacks, focusing on critical infrastructure vulnerabilities in the United States. Dr. Darren Pulsipher interviews Eric O’Neill, a celebrated former FBI counterintelligence operative known for capturing one of the most damaging spies in US history, Robert Hanssen. The conversation moves from O’Neill’s gripping background to a sobering look at cyber threats facing America, practical frameworks for defense, and the importance of proactive, intelligence-driven security at both national and personal levels.

Detailed Breakdown

Eric O’Neill’s Background and the Robert Hanssen Case (01:26 – 08:04)

• Origin Story:
  Eric shares his early career as an undercover FBI operative specializing in counterintelligence and anti-terrorism.
  • "My earliest job that really matters was working undercover for the FBI. I was a counterintelligence and counter terrorism undercover operative, which meant I chased spies and terrorists all over..." (01:26, Eric)
• The Hanssen Operation:
  O’Neill goes undercover at FBI HQ to catch Robert Hanssen, a notorious spy for the Soviet Union/Russia, code-named "Gray Suit".
  • “At one point during his career, he was asked to catch Grey Suit. So he was asked to catch himself, which was insane, right?” (03:26, Eric)
• Cybersecurity Connection:
  Hanssen headed the information assurance section, focusing on FBI cybersecurity, making the case a direct intersection between espionage and cyber defense.

Notable Quote:

"Robert Hanssen...survived for 22 years of his 25 year career... he was known only under the code name Gray Suit. This mythological legendary figure that the entire intelligence community had been hunting for decades." (02:19, Eric)

The Modern Nation-State Cyber Threat Landscape (08:04 – 14:24)

• United States “Under Siege”:
  O’Neill describes the heightened and ongoing cyberwarfare waged by foreign adversaries—specifically China, Russia, Iran, and North Korea.
  • “The Cold War never ended for Russia and China has jumped on the bandwagon. Iran knows that the only way they can attack us here in the homeland is through cyber.” (08:41, Eric)
• Critical Infrastructure as Key Target:
  SCADA systems, power grids, water supply, sewage, financial sectors, and telecom are the primary targets.
  • “The only real realistic threat, is a large scale cyber attack that denies us the critical infrastructure that makes our lives happy, healthy and whole.” (00:00 & 09:17, Eric)
• Probing Attacks:
  Nation-state actors launch reconnaissance and maintain persistence in infrastructure to test and exploit vulnerabilities.

Notable Quote:

“Cyber attacks, cyber terrorism...allows any country that has a bone to pick with the United States to attack us on our homeland, whether it's stealing information, actually stealing money, or preparing for a future war.” (08:56, Eric)

U.S. Infrastructure Challenges & Vulnerabilities (11:35 – 15:22)

• Decentralization as Double-Edged Sword:
  The U.S. grid is patchwork—state-run, federal, and private. This makes blanket attacks harder but not impossible.
  • “Here in the US, our power grid is...a patchwork grid. But...if nine separate sub grids are brought down at once, the entire grid collapses under its own weight.” (12:17, Eric)
• Water Systems Complexity:
  Numerous autonomous districts, e.g., California counties, each with unique infrastructures—harder to attack as a whole but not immune to impact.

Federal Response & Practical Gaps (14:24 – 16:30)

• Inconsistent Government Action:
  Federal efforts to secure critical infrastructure have lacked consistency and speed, regardless of administration.
  • “It hasn't been great in any of the last administrations...And that's the problem with administrative oversight and some of the red tape that happens.” (14:26, Eric)
• Basics Still Missing:
  Many organizations fail to implement foundational cyber hygiene (patching, 2FA, basic controls).
  • “The Cybersecurity 101, right...are the 99% things that you should be doing we are not doing across the board.” (15:37, Eric)

Memorable Moment:

"I don't think a change is going to happen until there is a large scale cyber attack." (16:30, Eric)

Why the System Waits for Crisis (16:30 – 19:44)

• Pearl Harbor Effect:
  The U.S. historically mobilizes only after catastrophe.
  • “We weren’t ready for World War II until Pearl Harbor.” (16:34, Darren)
• Criminal Threats Now Rival Nation-States:
  Modern ransomware syndicates can paralyze entire cities/companies. Double extortion is now common (“double extortion attacks where they steal a lot of data...and they tell the city, you know, we're going to publish all this if you don't pay.” – 17:50, Eric)
• Colonial Pipeline Example:
  Administrative-side attack led to a full operational shutdown, causing a fuel crisis.
  • “They didn't have the ability to say...‘let's shut down all the administrative, segment it from operational and continue to pump gasoline.’ They do now. They didn't then.” (18:47, Eric)

Notable Quote:

“The only difference between a foreign intelligence service cyber attack and a cybercrime syndicate cyber attack is the outcome. They use the same protocols, the same tool bag.” (20:56, Eric)

Defense Frameworks – "PAID" & "DICED" (22:09 – 29:06)

PAID – An Actionable Security Methodology

• Prepare: Proactively set yourself up with good practices (e.g. strong passwords, 2FA, skepticism online)

• Assess: Constant vigilance, treat security as dynamic, not static

• Investigate: Be ready and able to dig into suspicious messages and activity

• Decide: Take action—don’t freeze when faced with threats

  • “As an individual, you can do all of this and as a CISO...the only difference is scale.” (22:16, Eric)
  • “People don’t act. They feel like I can’t or it won’t happen to me, or they put their heads in the sand.” (23:00, Eric)

DICED – Understanding Attacker Tactics

• Deception

• Infiltration and Impersonation

• Confidence schemes

• Exploitation

• Destruction

• “There are six different ways they attack...that acronym, by the way, comes out to dice.” (28:15, Eric)

Memorable Quote:

“The number one thing that we as individuals have to do is learn about it, is understand the different ways that we're being attacked. If you can see the attack coming, then you can defend against it.” (28:25, Eric)

Role of Individuals, Organizations, & Reporting (25:21 – 29:06)

• Act Locally, Report Effectively:
  Local law enforcement can help with cybercrime; FBI is essential if espionage/nation-state involvement is suspected.
  • “If they think it’s a nation state, then they will come in and help. If they think it’s espionage, they will come in and help.” (26:09, Eric)
• Personal Vigilance:
  Everyone can be a "spy hunter" by using PAID and DICED.
• Fostering a Security Culture:
  “We are responsible for protecting ourselves.” (28:05, Eric)

Resources & Continued Learning (29:06 – 30:32)

• Eric’s Books:
  "Gray Day" (Hanssen case) and "Spies, Lies and Cybercrime" (practical cybercrime defense)
• Newsletter and Community:
  Weekly newsletter at EricONeill.net offers ongoing updates and community for defenders.
  • "...every week on Tuesday morning, I publish a newsletter that keeps the book alive...with cyber attacks, they never stop." (30:08, Eric)

Notable Quotes & Moments with Timestamps

• Eric O’Neill on the Big Threat:

  “The only real threat to the United States right now, the only real realistic threat, is a large scale cyber attack that denies us the critical infrastructure that makes our lives happy, healthy and whole.” (00:00, Eric)

• On Motivations and Tactics:

  “The only difference between a foreign intelligence service cyber attack and a cybercrime syndicate cyber attack is the outcome... They use the same tactics, the same protocols, the same tool bag.” (20:56, Eric)

• On Defensive Mindset:

  “The number one thing that we as individuals have to do is learn about it, is understand the different ways that we're being attacked. If you can see the attack coming, then you can defend against it.” (28:25, Eric)

• Actionable Acronyms:

  “PAID stands for prepare, assess, investigate and decide.” (22:11, Eric)
  “Counterintelligence is DICED and the cyber spy hunting is PAID.” (28:20, Eric)
