ChainCatcher message, zkLend announced a compensation plan. Deposits in unaffected pools are expected to receive full refunds, while deposits in affected pools will receive partial refunds and zkLend will restore the claims positions of the pools, with the withdrawal process expected to begin within 2 weeks after the review of the claims portal.Repayments will be fully covered by the available liquidity in each unaffected pool. If there is a shortfall in any unaffected pool (due to relatively high utilization), the remaining liquidity from other unaffected pools will be used to cover the shortfall. All accumulated surpluses from unaffected funds will be liquidated and proportionally distributed to each affected fund, with partial repayments being made based on the remaining liquidity of each fund plus such redistributed (socialized) surpluses proportionally.zkLend stated that after team contributions, the total funding gap has been reduced to approximately $9,013,101.72323417.

ChainCatcher news, Slow Mist founder Cosine posted on X confirming that the hacker who attacked zkLend is the same as the hacker who attacked EraLend in July 2023.

ChainCatcher news reports that according to Yu Xian, the founder of Slow Mist, the lending protocol zkLend on the Starknet chain was hacked on February 12, resulting in losses exceeding $9.5 million. The reason for the attack lies in the safeMath library used by its market contract, which employs direct division for calculations. This led to a rounding error in the actual number of zTokens that needed to be burned during withdrawals, which the attacker exploited for profit.On-chain data shows that the attacker's address has an active history of 235 days and has interaction records with multiple platforms, including Binance. The hacker has since transferred the stolen funds across chains, with most of it moved to the Ethereum network. Yu Xian stated that by tracking the associated Starknet addresses, it was discovered that this attacker is linked to the hacking incident of EraLend on July 25, 2023.

ChainCatcher message, StarkWare posted on the X platform stating that the dApp zkLend built on Starknet was attacked by hackers. The StarkWare team immediately initiated a coordinated response and took the following steps:Alerted the zkLend team to suspicious activities.Worked closely with cybersecurity firms to investigate the incident.Confirmed that the vulnerability does not involve a flaw in Starknet's core technology, but rather an irreparable application-specific issue.

ChainCatcher message, regarding today's zkLend theft of over 9 million dollars, SlowMist released an analysis stating that the core reason for this attack lies in the safeMath library used in the market contract. During division calculations, direct division was used, resulting in a rounding vulnerability when calculating the actual amount of zToken that needs to be burned during withdrawals. Attackers may exploit this vulnerability to gain illegal benefits.Users are advised to closely monitor their asset status on zkLend and temporarily halt any deposit actions related to zkLend to avoid potential losses.

ChainCatcher message, Slow Mist Yu Sen posted on platform X stating that hackers have cross-chain transferred the stolen funds from zkLend on the Starknet network to other networks, with most of the funds flowing to the Ethereum network.

ChainCatcher news, according to Cyvers Alerts monitoring, the lending protocol zkLend suffered a vulnerability attack on the Starknet network, resulting in a loss of $4.9 million. The attacker attempted to transfer the stolen funds across chains to Ethereum and launder them through the privacy protocol Railgun, but due to Railgun's policy restrictions, the funds were forcibly returned to the original address.In previous news, zkLend has offered a 10% white hat hacker bounty to the attacker through on-chain messages, and the related transaction has been confirmed on the Ethereum blockchain.

ChainCatcher message, zkLend suffered a hacker attack this morning. The team issued an announcement through the ZEND token deployer account, proposing that the hacker may keep 10% of the funds as a white hat reward, but must return the remaining 3,300 ETH to a designated address by February 14 at 00:00 (UTC). zkLend promises that once the transfer is received, all liabilities of the hacker in this attack will be waived.Earlier news stated that zkLend reported a security incident and has urgently suspended the withdrawal function, urging users to pause deposit and repayment operations.
