In 2014 I went nearly a week without sleep. I was running PayPal and attackers were inside our corporate network. They'd compromised an eBay employee's laptop, got onto the VPN, taken over a domain controller and made themselves domain admins. eBay and PayPal were one company then, on one Windows network. They stole 145M eBay user records, then came for the segregated vault holding PayPal's card credentials. We fought them off. They never got in, but they got close. Too close. Yesterday Binance lost ~$6.3B in what looks like the same way. A DevOps engineer's laptop, then a service inside the withdrawal stack, then withdrawals the signer approved because they came from a trusted source. Hot wallets emptied in under four hours. No key was stolen. Nobody broke cryptography or a ledger. They found someone with access and used the trust that came with it. Banks get hit exactly the same way. 2016: attackers inside Bangladesh Bank used its own SWIFT access to send $951M of payment orders to the NY Fed. $81M was lost. The rest was held because an unrelated sanctions filter tripped on the word "Jupiter". That was luck, and it only worked because wires took days to settle. June 2025: an IT employee at C&M Software, which connects Brazilian banks to Pix, sold his credentials for about $2,700. Attackers used them to send fake Pix transfers out of six institutions' reserve accounts at the central bank. ~$140M in under three hours. August 2025: stolen vendor credentials at Sinqia, another Pix connector. ~R$710M out of HSBC and one other institution in a single afternoon. The central bank froze most of it, after it had already moved. Same attack every time. Speed is what changed. When settlement took days, a filter, a correspondent bank or someone in ops could catch a bad payment. Pix, FedNow, SEPA Instant and blockchains settle in seconds. Payment security was mostly built for the slow world. PayPal's card and user data survived 2014 because domain admin on the corp network couldn't unlock it quickly enough, and our alerting caught the unusual activity on the network. That's the model. Approval policy no laptop or vendor login can reach. Velocity and anomaly limits enforced outside the system that sends. Dynamic caps on what any one wallet, account or service can move per hour. All of it in real time. About $3B of what left Binance has been frozen, almost all of it stablecoins. The $1.4B in bitcoin is sitting in 19 wallets and nobody can touch it. I don't think that's the problem. For decades the ability to reverse a wire or a card charge let a lot of weak security slide. You either stop the transfer before it's signed or you eat the loss. Nothing about the technology failed here. The chains processed exactly the transactions they were handed. Binance's own systems handed them the wrong ones because an engineer's laptop was compromised. That's operational security. eBay in 2014, Bangladesh Bank and two Pix connectors all failed at it on their own rails. In 2014 the attackers never reached the vault. If they had, the fraud losses would have been the small part. PayPal existed so people could pay without handing their card details to every merchant on the internet. We held those details so they didn't have to. Losing them would have broken the one thing the company was built on, and I'm not sure we would have recovered. I expect blockchains and digital assets to become the standard way money moves. Every custodian of digital assets, or of fiat on a real-time rail, is in that position now. The controls have to adapt to settlement in seconds, crypto or not.

BINANCE’S CZ CLASHES WITH ELON MUSK OVER $6 BILLION HACK Binance founder CZ asked Elon Musk to stop trolling after Musk reacted to a post comparing Binance’s assurances to FTX’s claims before its collapse. “Elon, have a lot of respect for you, but bad time to troll. Please stop,” CZ wrote. CZ added that Binance’s $500 million investment in Musk’s Twitter acquisition is now worth more than $1 billion. Binance co-CEO Yi He also weighed in, saying the exchange generates enough annual revenue to cover the losses without selling its SpaceX shares.

Binance's initial investigation suggests that the security incident may involve a compromised DevOps engineer’s laptop, which allowed an attacker to gain access to a service container and submit unauthorized withdrawal transactions. We have found no evidence of any wallet private key leak. We will share a detailed technical post-mortem once the investigation is complete and the facts are fully verified. The estimated total impact sits at around $6.3B. We have worked with blockchain partners to freeze affected assets, with ~$3 billion frozen on-chain so far. Binance will cover all losses from the SAFU fund and the company’s funds. User funds are safe. We will also publish an updated Proof of Reserves once the remediation is complete. As an immediate precaution, Binance has: - temporarily suspended deposits and withdrawals while security checks are completed; - revoked the affected address authorisation; - engaged law enforcement and blockchain intelligence partners to trace and recover funds. Our teams are working around the clock to resolve this issue safely and thoroughly. We are working closely with our law enforcement partners to confirm the identity of these criminals and bring them to justice. Please rely only on official Binance channels for updates. Please feel free to contact Binance Customer Support if you have any further questions. binance.com/en/support/annou…
