Binance Suffers Biggest Crypto Hack In History With $6.3 Billion Affected [UPDATE]

UPDATE 10/30/26: Binance has temporarily suspended customer withdrawals after suffering what investigators say is the biggest crypto hack in history. According to Binance CEO Yi He, the company estimates roughly $6.3 billion in funds were impacted, with roughly $3 billion in assets frozen on-chain so far. Rest assured, "your money is safe, and we're covering every loss," said co-CEO Richard Teng in a LinkedIn post.

"This was a complex attack," said Teng. "The attacker also used a self-destruct mechanism that destroyed tooling and tracers, making it more difficult for us to trace." From a report: Teng said the incident was not carried out by one person. While the initial investigation indicated the involvement of a compromised laptop, further digging revealed additional points of breach. [...] Blockchain analysis firms TRM Labs and Elliptic have linked the theft to North Korean hackers, with TRM attributing it "with high confidence" to a group known as TraderTraitor, the same group responsible for last year's Bybit hack.

Elliptic estimated Friday that about 44% of the stolen assets have been frozen, with stablecoins accounting for nearly all of those funds. The firm estimated that attackers still controlled over $3 billion in crypto that token issuers cannot directly freeze.

The hackers appear to have compromised Binance's wallet-signing infrastructure, allowing them to authorize transactions that drained billions of dollars in cryptocurrency across multiple blockchains, according to the firms. Binance, in its preliminary stage, has conducted an investigation into the hack, which suggests the incident may have begun with a compromised engineer's laptop. The exchange added that it has found no evidence that wallet passwords were leaked. Below is the original story from yesterday, Oct. 29th.

Binance is investigating a potential hack after more than $2 billion in crypto was drained from one of its wallets into a new external account, with Blockaid estimating nearly $3.3 billion was moved.

"Our teams are aware of reports of a potential security issue and are actively investigating," said Binance on X.

"User funds are safe," said Binance founder CZ. "It does look like a hack on Binance. Appreciate the quick freeze from Tether (~$971m) and Circle (~$823m). I don't manage Binance anymore, but as a shareholder, I expect all user funds will be fully covered."

At around the same time, crypto-based prediction market Polymarket reported its own security incident that wiped out around $2.7 million in user funds.
