erc-20 smart contract security

A team of blockchain security analysts at Chains Guard recently made public that a third party ERC-20 smart contract code being used by one of their teams was secretly transferring customer funds to an unknown wallet.

According to Zer0Man, a security analyst at Chains Guard, the smart contract was supposed to make a transfer of funds between two addresses, but the contract also included code to execute an additional transfer to a wallet owned by the smart contract writers, of a 1% of the overall amount of the operation.

Although this could be considered a transfer commission, after a research performed by the security consulting company, it was confirmed that the contract provider did not stated this commission or fee anywhere, therefore it was being charged illicitly to the customers in a type of hidden backdoor in the smart contract.

This example highlights the need of security auditing of 3rd party smart contract, and the convenience of self-deployment of smart contracts in order to ensure that the service provider remains on top of what is being executed by the contract.
