Inside Zero-Days: Nicole Perlroth Warns of Digital Doomsday Arms Race
Nicole Perlroth explains the shadowy global market for zero‑day vulnerabilities, how governments and brokers buy and weaponize them, and why this fuels a new era of “mutually assured digital destruction.”
She traces the culture and ethics of hackers, the evolution from hobbyist curiosity to lucrative offense, and the enormous collateral damage from ransomware and state cyber operations on hospitals, infrastructure, and businesses.
Perlroth and Lex Fridman discuss individual security practices, structural weaknesses in U.S. critical infrastructure and regulation, and why basic defenses like multi‑factor authentication still block most attacks.
They close with broader questions about surveillance, intelligence agencies, whistleblowing, the future metaverse, and why cultivating ethical defenders and authentic, informed citizens is essential to avoiding worst‑case outcomes.
Key Takeaways
Zero-days are now a mature global market and core state capability.
Previously niche bugs, zero-day exploits are now routinely bought for six- and seven-figure sums by governments and brokers, putting powerful surveillance and sabotage tools into the hands of many nation-states and some authoritarian regimes.

Basic cyber hygiene still stops the majority of attacks.
Perlroth stresses that multi-factor authentication, proper patching, and not reusing passwords would prevent a huge portion of real intrusions—including headline incidents like Colonial Pipeline, which hinged on a single unprotected, old account.

Ransomware has moved from nuisance to national security threat.
Modern ransomware, increasingly using zero-days and supply-chain vectors, can shut hospitals, paralyze cities, and disrupt vaccine production; paying or not paying often presents agonizing trade-offs between funding criminals and preserving essential services.

U.S. critical infrastructure is structurally vulnerable and poorly regulated.
Because over 80% of critical infrastructure is privately owned, with minimal mandatory security standards or breach reporting, adversaries can quietly pre-position in pipelines, grids, and plants, planning leverage in future geopolitical crises.

The offense–defense imbalance and talent gap are dangerous.
Offense is sexier and better funded, drawing hackers to zero-day sales and offensive agencies; meanwhile, millions of defensive roles go unfilled globally, leaving hospitals, utilities, and companies under-protected against increasingly sophisticated attackers.

Attribution and proxies make cyber ‘Geneva Conventions’ hard to enforce.
Unlike nuclear weapons, cyber tools are cheap and deniable; states can outsource to criminals or “patriotic” hackers, muddying responsibility and complicating any attempt to ban attacks on civilian targets like hospitals or power grids.

Usable, privacy-preserving security and authentic behavior are crucial.
Security that adds too much friction gets ignored; solutions like better 2FA, hardware keys, behavioral detection, and data vaults must be easy to use, while individuals are safer—socially and digitally—when their public and private selves align.

If one side is hacked, you can just unleash all hell.
We have stumbled into this new era of mutually assured digital destruction.
How far are people willing to go?
You can capture their location. You can capture their contacts that record their telephone calls, record their camera without them knowing about it. Basically, you can put an invisible ankle bracelet on someone without them knowing. You could sell that to a zero-day broker for $2 million.
The following is a conversation with Nicole Perlroth, cybersecurity journalist and author of This Is How They Tell Me The World Ends: The Cyber Weapons Arm Race. This is the Lex Fridman Podcast. To support it, please check out our sponsors in the description. And now, dear friends, here's Nicole Perlroth. You've interviewed hundreds of cybersecurity hackers, activists, dissidents, computer scientists, government officials, forensic investigators, and, uh, mercenaries. So let's talk about cybersecurity and cyberwar. Start with the basics. What is a zero-day vulnerability and then, um, a zero-day exploit or attack?
So (sighs) at the most basic level, let's say I'm a hacker and I find a bug in your iPhone iOS software that no one else knows about, especially Apple. That's called a zero-day because the minute it's discovered, engineers have had zero days to fix it. If I can study that zero-day, I could potentially write a program to exploit it, and that program would be called a zero-day exploit. And for iOS, the dream is that you craft a zero-day exploit that can remotely exploit someone else's iPhone without them ever knowing about it, and you can capture their location. You can capture their contacts that record their telephone calls, record their camera without them knowing about it. Basically, you can put an invisible ankle bracelet on someone without them knowing, and you can see why that capability, that zero-day exploit, would have immense value for a spy agency or a government that wants to monitor its critics or dissidents. And so there's a very lucrative market now for zero-day exploits.
So you said a few things there. One is iOS. Why iOS? Why- which operating system? Which one is the sexier thing to try to get to or the most impactful thing? And, uh, the other thing you mentioned is remote versus, like, having to actually come in physical contact with it, though. Is that the distinction?
So iPhone exploits have just been a government's number one priority. Recently, actually, the price of an Android remote zero-day exploit, something that can get you into Android phones, is actually higher. The value of that is now higher on this underground market for zero-day exploits than an iPhone iOS exploit. So things are changing.
So the- there's probably more Android devices, so that's why it's better, but then the iPhone side, if I- so I'm an Android person because I'm a man of the people, but it seems like all the elites use iPhone, all the people at nice dinner parties. So, uh, is that, is that the reason that, like, the more powerful people use iPhones? Is that why?
