Hyperliquid Rekt: Market Manipulator Drains Millions in Flash Attack

Another day, another DeFi bloodbath—this time Hyperliquid takes the hit. A single actor exploited market conditions to siphon funds in a textbook manipulation play. Who needs regulators when you’ve got crypto’s self-correcting… uh, 'free market'?

How it went down: The attacker identified a liquidity gap, pumped the asset, then dumped hard—leaving Hyperliquid’s treasury lighter and traders fuming. Classic rinse-and-repeat, but with zero consequences (so far).

At this point, the perpetrator’s $3 million collateral was entirely wiped out. The system’s protective mechanisms could not avert this loss within the few seconds it transpired.
