The ZKSYNC association has confirmed the resumption of $ 5 million in stolen chips of a ZKSYNC security incident on April 15, involving its airline distribution contract.
The pirate agreed to accept a premium of 10% and to return 90% of the remaining stolen tokens, transferring the ZKSYNC Security Council nearly $ 5.7 million to three transfers on April 23.
“We are pleased to share that the pirate cooperated and returned the funds in the deadline for Safe Harbor,” said the Zksync Association on X on April 23, which was then replaced by the ZKSYNC X account.
Matter Labs, the company behind the Zksync protocol, also republished the news shared on X.
The ZKSYNC X account previously confirmed that no user funds were compromised.
The pirate sent two transfers to the Blockchain of the Zksync era, made up of $ 2.47 million of Zksync (ZK) token (ZK) and $ 1.83 million ether (ETH) to the Zksync Security Council Zksync ether ether (ETH).
776 other ETH worth almost $ 1.4 million were also sent to Ethereum address of their Security Council, according to Etherscan data.
The first transfer was made on April 23 at 2:39 p.m. UTC and the last transfer was made about 13 minutes later – all in the 72 -hour window that ZK Sync had initially fixed.
The ZKSYNC association said that the company would publish a final report revealing more details of the security incident.
How the hack happened
The pirate violated the administration account of Zksync, allowing them to exploit the function of Sweepinclamed () of the Airprop distribution contract for Front 111 million un demanded ZK tokens, worth around 5 million dollars at the time of the attack on April 15.
Piracy occurred while Zksync was winning 17.5% of ZK’s token supply to the participants in the ecosystem.
The amount recovered – almost $ 5.7 million – exceeded $ 5 million originally stolen due to an increase in the market value of stolen chips, with ZK and ETH increasing 16.6% and 8.8% since the attack on April 15, according to Coindecko data.
Despite the recovery of assets, the ZK token has failed to increase considerably to news and is currently down 0.2% in the last 24 hours.
The ZKSYNC era is an Ethereum Layer 2 solution which uses zero knowledge rolls for lots transactions and treat transactions outside the chain. According to Defillama and Rwa.xyz, have almost $ 59 million of total value locked on its channel and has more than $ 2 billion in real assets.
