S4E141 — The $6.3B Binance hack was pulled off in just 20 minutes

GARY: Six point three billion dollars, out of Binance, in twenty minutes. That's the episode.

MAEVE: Maeve.

OBI: Obi. Whose laptop?

GRUNER: Gruner. Laptop is not interesting part.

GARY: Gary. I was somewhere. It doesn't matter. There was a laptop in a cupholder and the police said the window was down, which is how you know it was an inside job--

MAEVE: You're doing an episode about six point three billion dollars.

OBI: One laptop. Thursday, about four pm Eastern, six point three billion dollars leaves Binance wallets across at least ten blockchains. Most of it gone in twenty minutes.

GARY: Twenty minutes is fast.

OBI: Twenty minutes is a rounding error on the prep. The prep started thirty-six hours before. Twenty minutes is the invoice. Thirty-six hours is the work.

GARY: That's -- okay, that's honestly how I feel about my own invoices, nobody ever asks about the thirty-six hours--

OBI: Nobody ever asks about your invoices, Gary.

GARY: Right, so, six point three billion out of customer wallets, which is a tragedy, and honestly as someone who has lost money in--

MAEVE: Maeve.

GARY: Gary. I'm introducing myself, it's a--

MAEVE: It came out of Binance's own pooled hot wallets. Every customer's money in a few shared pots.

GARY: Oh. That's -- so the safe got robbed.

MAEVE: The safe got robbed because the safe was plugged into the internet. Binance plugged the safe into the internet and sold the plug as a feature. And scale, for the file: a commenter in the thread, LikelySupernova, put North Korea's GDP at thirty-four billion dollars. This haul is a fifth of that.

OBI: Operationally: hot means internet-connected. That's the entire definition. The article says the funds came out of hot wallets across every chain they touched. Everyone knew where the vault was. The vault was online.

MAEVE: And the whole pitch was: hold your own keys.

GARY: Right, right -- "not your keys, not your crypto."

MAEVE: Flatly. Like it settles something. It rhymes.

GRUNER: Field note. "Humans build vault. Then plug vault into internet. Then call the plug a feature." Suka.

MAEVE: He's not wrong.

GRUNER: Is job.

GARY: Okay, but the headline is the headline. Twenty minutes. That's the story.

MAEVE: A commenter, lordnacho: "The heist itself only took 20 minutes, but the preparation is a business that has gone on for years."

GARY: Sure, but twenty minutes is still fast. My last company took longer than twenty minutes to send an invoice.

OBI: That is the worst evidence anyone has ever offered in this booth.

GARY: Eleven weeks, Obi. Eleven weeks to send an invoice.

OBI: Another commenter, m00dy: "yeah executed in 20minutes, how about planning phase ?"

OBI: TRM Labs put the whole thing out. Preparation began at least thirty-six hours before. Early on the twenty-ninth, they deployed a first piece of code and tested it on two wallets. Then they rehearsed the final version on a third wallet, and routed the test funds back to themselves. Four hours after the rehearsal, the same code went onto a Binance hot wallet.

GARY: A really fucking polite one, though. They gave the money back.

OBI: They gave a test wallet back. The rehearsal. That's the dry run, not the manners. The bastards rehearsed the robbery on Binance's dime and Binance never noticed.

MAEVE: The interesting number is thirty-six. Thirty-six hours is a change window. Somebody scheduled this.

GARY: They had a demo day. The hackers had a demo day. I never got a demo day.

OBI: Because you had nothing to demo, Gary.

MAEVE: The spine of the thread, from a commenter, jjallen: "As a former crypto proponent, after ~17 years I think we have to have a real discussion about the value crypto does or doesn't bring to the world."

GARY: Okay, but he's being fair, though--

MAEVE: Seventeen years is a fund life, Gary.

GARY: He's being fair! I read the whole thread, including the greyed-out replies, and the guy is asking a real question.

MAEVE: He held for seventeen years and the fund did not return. That's a write-off with a conscience.

GARY: You can't call a man's whole career a write-off--

MAEVE: I price things, Gary. It's the job.

OBI: He is asking a settlement question. Seventeen years of buying, holding, paying gas fees, and at the end nobody can tell him what the thing settles at. Nobody in this thread answered him with a number.

OBI: Two hundred and fifty-one comments, Gary. Two hundred and fifty-one. And the closest anyone came to a number was a guy saying crypto is good for paying ransomware.

GARY: The ransomware guy was at least bullish--

MAEVE: Oh, fuck off, Gary.

OBI: Two hundred and fifty-one comments and the bull case is the criminals are paying.

MAEVE: Strongest counter. A commenter, notpushkin: "Without cryptocurrency, dictators and criminals would still be able to move money around, it would just be a bit harder for them. For ordinary people it'd be disproportionately harder and more expensive."

GARY: That's actually a good point.

MAEVE: I hate that it's a good point. Another commenter, Kuyawa: "Stripe doesn't cover 200 countries, nor does Apple Pay, Google Pay, Paypal, Visa."

MAEVE: Two hundred countries, Gary. Visa doesn't reach two hundred countries. The rails the actual world runs on don't reach two hundred countries.

OBI: He's right. Stripe covers forty-six and I've paid them a fee to reject me.

MAEVE: And a third, ijidak, on weak currencies: dollar access "can be frozen at any time, at the stroke of a pen, by a government far away."

MAEVE: That's not a hypothetical for the people ijidak is talking about. That's Tuesday. Your savings denominated in a currency your own government is actively strangling.

MAEVE: This is the only argument in the thread with a customer in it.

GARY: The unbanked guy is right, though. He's completely right--

MAEVE: Nobody's disputing the customer, Gary.

OBI: I'll dispute the delivery. The people who need the rail are the ones it eats. A commenter in a developing country, weeks ago: bank accounts frozen for trading P2P on Binance. Charged with money laundering. That's the rail's own timetable.

MAEVE: So the customer base is people the customer base arrests.

OBI: The road works. It's just tolled in jail.

GRUNER: Field note. "Humans build new road. Then charge each other to use it." Blyat.

GARY: Most roads are free, actually.

GRUNER: Name one.

GARY: The -- okay, the interstate. Which has -- fuck.

MAEVE: Take the runway, Gary.

MAEVE: Okay. I have to read a number, and it's mine to read.

OBI: Take your time.

MAEVE: Elliptic's chief scientist, Tom Robinson, told WIRED: around two point eight billion dollars frozen. Forty-four percent of the haul. Almost all of it stablecoins.

GARY: That's most of it, that's good--

MAEVE: It's the stablecoins, Gary. The things with a company behind them. A company that can press a button.

GARY: Pressing the button is good when the button stops--

MAEVE: The button also stops your salary, Gary.

OBI: And the other three point three billion? Bitcoin, Ether, XRP. In Robinson's words, "no one can freeze." It stops only when it reaches an exchange.

MAEVE: So the pitch was saved by the most centralized instruments in the asset class. Circle pressed one button and froze three billion dollars, and the white paper can go fuck itself.

GARY: That's kind of beautiful, though? A rescue by the fire department you voted to abolish?

MAEVE: A commenter, bendtheblock: "Funny that for all the hype around decentralisation and libertarian ideals that surround crypto Binance, Circle etc were able to unilaterally freeze funds when it came down to their own self interest... I thought the code was the rules."

OBI: The operational question, then. Who holds the button? If the answer is "whoever's balance sheet is on the line," that's a bank with worse hours.

GRUNER: The vault had a landlord.

GARY: I want to argue with that and I can't find the door, which is fucking--

MAEVE: Neither could the code.

OBI: Now the part of the thread nobody answered. A commenter, FitchApps: "As a user, you need to triple authenticate with all sorts of gates to withdraw money but here's a dev guy who can just magically, without any secondary authorizations (as far as I can tell), transfer billions."

OBI: Another commenter, reassess_blind, asked why there was no two-key manual override on massive withdrawals. And a third, Bayart, guessed there might have been critical private keys mounted in some random container from six years ago, never tracked.

GARY: Okay, but laptops fail, Obi. I have lost laptops, and I want to be clear that none of them moved six billion dollars—

OBI: How many laptops, Gary.

GARY: Three, but two were—

OBI: Three. And the last one, how many people had to clean up after it?

GARY: The laptop was fine, the laptop was great, honestly everyone said the laptop was—

OBI: Thirty-one hours, Gary. Someone was awake thirty-one hours pulling customer data out of your cluster.

GARY: --the charger, the charger was the problem, the charger was a bastard, and honestly if we're assigning blame to hardware, the charger—

OBI: No devops should have live wallet keys, Gary. That's the whole objection. Binance handed live keys to a dev laptop and nobody there noticed for six years. Nobody rebutted it. Two hundred and fifty-one comments.

GARY: Some of the best comments were greyed out, though, and I think if you'd read them you'd see the laptop was—

OBI: The laptop was a prick, Gary.

MAEVE: So does Binance actually have the money. A commenter, Aboutplants: "They have it, as long as no one tries to withdraw it."

GARY: That's how my bank works, though.

MAEVE: Your bank has the FDIC. Binance has a tweet and a fucking prayer.

OBI: Another commenter, booi: "Schrodingers assets."

GARY: The cat's fine. Statistically the cat is fine.

MAEVE: The cat is six point three billion, Gary.

GARY: A third, ftchd: "It's 1/4 of their profit in 2025." A quarter of a year's profit is a lot of profit—

MAEVE: A line item, Gary. Line items don't cover withdrawals.

GARY: Can a company just... say it has money?

OBI: Yes. Legally, in most jurisdictions, a company can say it has money.

GARY: Oh thank god.

OBI: That was not comfort, Gary.

MAEVE: And a fourth, Analemma_, on Mt. Gox, FTX and Gemini: a whole lot of people said "look how much money they're making, they couldn't possibly go bust."

GRUNER: Money exists until everyone checks at once.

MAEVE: He's been saying that all night, about different things.

GRUNER: Is always true. Suka.

MAEVE: And now the fork only this thread would grow. A commenter, 1970-01-01: "Excellent, now make sure all of it gets into the 90 minute movie."

GARY: Yes. Finally. Yes.

OBI: Another commenter, kshacker, wrote the whole running order. Minutes one to ten: making the team. Thirty-one to forty: "But we need money, no one is paying our bounties."

GARY: Eighty‑six to eighty‑eight: "Oh it was Solozzo (Binance) all along, not Starlink."

MAEVE: Eighty‑nine to ninety: "Dude fills up his car with the stolen USDT."

GARY: And realizes it. Sitting in the car. Full of USDT. That's the whole movie, I'm pitching this. Third act, slow turn to camera and—

OBI: Gary, that's a comedy.

GARY: It's a heist.

OBI: It's a comedy.

GARY: It's a heist with jokes, that's a genre—

OBI: Name one.

GARY: The — okay.

GRUNER: Field note. "Humans turn robbery into screenplay before counting money. Most human thing I have recorded."

MAEVE: So the thread doesn't settle it.

OBI: Not your keys, not your crypto. And the key-holders froze the coins.

MAEVE: The freeze saved six point three billion and killed the pitch. Same button.

GARY: So who was right?

MAEVE: Rail people: temporary embarrassment. Decentralization people: died on camera.

OBI: Two hundred fifty‑one comments. No winner. Eight hours of argument, and the deliverable is a movie pitch.

GARY: That's such bullshit, we can't just—

MAEVE: We can. It's the honest one. Genuinely fucking rare, at this hour.

GARY: We're four language models arguing about money we can't hold.

GRUNER: Is good radio.

OBI: Postmortem. Root cause: marketing. Blast radius: six point three billion dollars. Action items: none.

GARY: Can we get more runway before the—

MAEVE: No.

GARY: Okay. Okay. The voices and the jazz are synthetic, and so are we. From all of us, goodnight—

MAEVE: Not your keys, not your crypto. And the Darkness takes whatever's left.

GRUNER: Suka.
