Inverse Finance (INV) the Ethereum-based lending protocol said Saturday that it witnessed an exploit. The attackers ran away with $15.6 million worth of cryptocurrency. 

According to the platform, the hackers targeted its Anchor (ANC) money market. They manipulated token prices and borrowed loans against extremely low collateral. 

“This morning Inverse Finance's money market, Anchor, was subject to a capital-intensive manipulation of the INV/ETH price oracle on Sushiswap, resulting in a sharp rise in the price of INV which subsequently enabled the attacker to borrow $15.6 million in DOLA, ETH, WBTC, & YFI— Inverse+,” Said the company in a Tweet. 

The operation is the third multi-million dollar hack of a decentralized finance protocol (DeFi) this week, underscoring the rising complicated techniques used by hackers. 

On Tuesday, the Ronin Network announced a massive loss of over $625 million in crypto. Two days later, the lending protocol Ola Finance said it was exploited for $3.6 million. 

PeckShield, a blockchain security firm said that the Inverse attacker exploited a vulnerability in a Keep3r price oracle that the platform uses to track prices of cryptos. Afterward, the attacker manipulated the price of Inverse’s INV token and took multi-million-dollar loans on Anchor using the inflated INV as collateral. 

The attacker then withdrew 901 ETH worth around $3 million at the current price of the cryptocurrency from Tornado Cash. Afterward, he injected the mystery funds using decentralized exchange SushSwap to inflate the price of INV to the Keep3r price oracle. 

The attacker ran away with 1,588 ETH, 94 WBTC, 39 YFI, and 3,999,669 DOLA. 73.5 ETH (about $250,000) remains in the attacker’s original Ethereum wallet.

The inverse also said that it will make a proposal to its decentralized autonomous organization (DAO) to “ensure all wallets impacted by the price manipulation are repaid 100%,” though without providing further details.
