$1.4 billion was hacked in Ethereum, which is a huge amount of ETH. 2 Apparently the trouble started with their cold wallet, where they keep a lot of their crypto offline. The investigation points to the North Korean Lazarus Group as the likely culprits, and it seems the attack originated from some malicious code within their wallet provider, Safe Wallet.
Currently there's a big push to track down the stolen funds, and Bybit's even offering a bounty, but it's unlikely the funds will be recovered. It's important to understand that this wasn't necessarily a fault of Bybit's own security, but rather a problem with the wallet provider they were using.
Bybit has reassured users that withdrawals remain unaffected and other cold wallets are secure. While investigations into the incident continue, early speculation about Bybit buying back ETH to cover losses, which briefly boosted ETH's price, was dispelled by CEO Ben Zhou. He clarified that a bridge loan covered 80% of the stolen ETH, and there are no plans for spot market purchases. The hackers now holds a substantial amount of ETH across multiple wallets, raising concerns about potential drops should they decide to sell, but this may occur gradually over many months or even years (since they didn't buy it / it will not matter at what price it is sold).
This hack coincides with ETHDenver, a major Ethereum event typically associated with bullish market conditions and optimism. But overall, the outlook for Ethereum isn't looking as bright as it usually would be and this may lead to a further sell-off once more people catch on.
