Action Type Old Value New Value
Changed Description 
An integer overflow in the batchTransfer function of a smart contract implementation for Beauty Ecosystem Coin (BEC), the Ethereum ERC20 token used in the Beauty Chain economic system, allows attackers to accomplish an unauthorized increase of digital assets by providing two _receivers arguments in conjunction with a large _value argument, as exploited in the wild in April 2018, aka the "batchOverflow" issue. NOTE: the OKEx exchange suspended BEC trading as of 2018-04-22; however, the integer overflow in this codebase can still be exploited through transactions involving other exchanges and/or other tokens.
