What happened
Vesper Finance tweeted that its No. 23 lending pool Vesper Lend beta launched on the interest rate agreement Fuse has been attacked again. The attacker manipulated an oracle and depleted the beta test borrowing pool of DAI, ETH, WBTC, and USDC of approximately $1 million. This is not an attack on the Vesper contract, no VSP or VVSP is threatened. Vesper has banned the lending of all tokens in Beta Vesper Lend Rari Pool #23, and also switched the oracle from VUSD/USDC to VUSD/ETH (Uni v3). Prior to this, the Vesper Lend loan pool on Rari Fuse was attacked, and the attacker made a profit of 3 million US dollars.
