The investigation showed that the administrator address of the airdrop contract (0x8428…587D) was compromised, and the attacker called the sweepUnclaimed() function to illegally mint about 111 million ZK tokens from three airdrop contracts, accounting for about 0.45% of the total supply. The incident was limited to the airdrop distribution contract, and the ZKsync protocol and its token contracts, governance contracts, and authorized minters were not affected.

According to the official announcement of ZKsync, the security team discovered that an administrator account of the airdrop contract was leaked, and the attacker controlled and sold about 5 million US dollars of unclaimed ZK airdrop tokens. The incident was caused by the leakage of a single key, which did not affect the protocol itself and the ZK token contract, and user funds are always safe. The official investigation is underway and a detailed report will be released later.
