U.S.M.S.C.S.C.T. WAS ATTACKED AT A LOSS OF ABOUT 70.83 ETH

On 10 August, according to slow fog monitoring, the United StatesM of the Decentralized Stabilization Currency Project was attacked, resulting in a loss of approximately 70.83 ETH. Reason: There are flaws in the pricing logic of ethFromDefund() in the USM Contract Defund() foreclosure function. This function, in a single foreclosure calculation, is calculated on the basis of an arithmetic average of the current FUM bid and the projected final FUM bid, but the algorithm does not have the same split. The combination of a single buyout with a state contraction factor (adjShrinkFactor) and an integer mechanism, an equal number of FUM assets, divided into 64 small foreclosure operations, and the total amount of overleaf that can eventually be extracted is much higher than a one-time large buyout。
