Binance hack update: How the $6.3 billion crypto hack happened

Binance, the world's largest cryptocurrency exchange, suffered a significant breach resulting in a loss of $6.3 billion. The attack occurred over several hours, during which the hacker drained Binance's wallets, siphoning a substantial amount of BTC, ETH, USDC, USDT, and other cryptocurrencies. While the exchange's co-CEO, Richard Tang, confirmed the total loss at $6.3 billion, crypto analyst Wazz estimated the figure to be $6.17 billion by analyzing crypto wallets.

Binance founder and CEO, Changpeng Zhao, did not disclose the exact amount, but he confirmed the approximate figure.

Initial reports revealed that the company's wallet private keys had not been compromised. Instead, it was a compromised DevOps engineer's laptop that the hacker exploited to gain access to a service container, enabling unauthorized withdrawal transactions. This incident raised concerns about the adequacy of Binance's security measures, as a single compromised laptop could potentially result in such a massive loss of funds.

Binance subsequently shared additional details about the incident, revealing that the attack process was more intricate than initially reported. The attacker gained access to a service container through the compromised laptop, subsequently submitting unauthorized withdrawal transactions. While the company has not attributed responsibility to any individual, it emphasized that no evidence of a wallet private key leak was found.

Binance stated that it would publish a detailed technical post-mortem once the investigation is complete and all facts are verified, as well as provide an updated Proof of Reserves.

Fortunately, a significant portion of the stolen funds has been frozen by the issuers. In response to Elon Musk's criticism, CZ mentioned that roughly $3 billion in funds had been frozen. The company also holds a SAFU fund worth over $1 billion and more than $1 billion in SpaceX shares, a playful jab at Musk.
