BlockBeats reported that on September 21, according to monitoring by Web3 security agency Ancilia, Inc., ShezmuETH (ShezETH) tokens appeared to be attacked, possibly due to a key leak. An additional 9,900 ShezETH tokens have been minted and exchanged for 332 ETH (worth $880,000).

In addition, ShezmuUSD was also hacked, and it is impossible to determine whether this is related to the Deployer key leak. The mortgage contract does not have mint() protection, which allows anyone to mint mortgage tokens.
