By now you've probably heard of the staggering blow to crypto exchange Bybit, as they confirmed a massive $1.4 billion exploit, making it the largest crypto hack on record

We're now learning some additional details - according to Bybit CEO Ben Zhou, the attacker compromised one of the exchange’s Ethereum cold wallets, siphoning off huge quantities of ETH and stETH by manipulating a single transaction.

Bybit’s CEO says the hacker got hold of the private keys to a specific ETH cold wallet and transferred the funds to an unknown address. Top blockchain analytics groups like ZachXBT and Arkham Intelligence have verified these massive outflows, with Arkham noting that the stolen funds are now being split and sold through multiple addresses.

Is User Money Safe?

Zhou insists that other Bybit wallets weren’t impacted. The platform is still processing withdrawals—99% of user requests have reportedly gone through without a hitch. Bybit is maintaining they have enough liquidity to honor customer withdrawals in full.

Setting a New Record...

This new $1.4 billion hack officially takes the top spot for the largest theft in crypto history. It surpasses both the Ronin Network’s $625 million loss and the $611 million Poly Network exploit, both of which rocked the market in 2022.

Catching the Hacker...

The biggest hack is now offering the biggest reward, up to $140,000,000 (10% of total hacked funds) for anyone who can track down who is responsible.

This is bad news for the hacker, because unless we're looking at a government sponsored action (such as North Korea) you can be sure the hacker bragged about his accomplishment at least within a small circle of fellow hackers - if so, with a reward this size someone is bound to turn on them.

Blockchain researcher ZachXBT was among the first to flag the suspicious outflows. He reports the stolen ETH has been split across 39 different addresses—likely an attempt to hide the funds and evade tracking.
