1. Thieves Took $6 Billion From Binance in 20 Minutes, and the Way In May Have Been One Engineer's Laptop
Binance is one of the largest cryptocurrency exchanges in the world. Its early finding is that the attackers may have gotten in through a single compromised laptop. The question for you is what one account or machine at your company can reach.
Binance, an exchange with more than 300 million registered users by the BBC's count, had about $6.3 billion stolen on Thursday October 29th, most of it in roughly 20 minutes. Chainalysis and TRM Labs, two firms that trace cryptocurrency, put the total at $6.36 to $6.4 billion, and the FBI says more than $6 billion. It is the largest crypto theft on record, roughly four times the February 2025 theft from the exchange Bybit, which the FBI put at about $1.5 billion.
It was planned. TRM traces the groundwork back at least 36 hours: the thieves funded the account they used to run the theft through a service that hides where money came from, then tested their code on the day. The money moved in one burst, with a second wave about three hours later.
Binance's early finding, relayed by ABC and the BBC, is that the attacker may have gained access through a compromised laptop belonging to a DevOps engineer, an employee who builds and runs the company's systems. ABC reports the investigation has since found additional points of breach, without saying where, and the technical report Binance promised is not out. TRM's own read is that the systems that approve payments out of Binance's wallets were compromised across several blockchains. Binance has not published a root cause.
On Saturday the FBI, with the Secret Service and IRS Criminal Investigation, attributed the theft to TraderTraitor, a North Korean group, though President Trump said the same day that Washington was not yet certain North Korea was involved. Chainalysis and TRM reached the same conclusion from the money trail, which mixed with funds stolen from the exchange Bitget in September. It is the third large exchange theft in 20 months tied to the same group.
Tether and Circle, the companies that issue the two largest digital dollars, froze about $1.8 billion of the stolen money within the hour and about $2.4 billion by that night, per TRM and the BBC. Frozen is not recovered, and TRM says the thieves still hold more than 420,000 ether and 18,270 bitcoin, two digital currencies that no company can freeze. Binance says it has replaced 95% of the stolen assets from its own funds, about $6 billion, and began resuming withdrawals in phases on Sunday.
