$5 million in tokens stolen from ZKsync

An attacker compromised an admin account belonging to the ZKsync Ethereum layer-2 project, which is built by Matter Labs. By doing so, they were able to steal approximately $5 million worth of the ZK token, which the project said were "the remaining unclaimed tokens from the ZKsync airdrop".

The ZK token quickly dropped around 20% in price, likely as a result of the thief trying to sell the tokens.

KiloEx exploited for $7.5 million

KiloEx, a decentralized perpetual futures exchange, was exploited for $7 million. An attacker executed an oracle manipulation attack on KiloEx's pricing smart contracts to steal funds across the Base Ethereum layer-2 chain, BNB Chain, and Taiko.

KiloEx halted trading on the platform while investigating the exploit, and contacted the hacker to try to negotiate a 90% return of funds.
