This story describes a cool hack, for over $300K (even nearly $600K, if done at the right time). It is a white-hat hack. We performed it off-chain, demonstrated to Dinngo, the authors of the vulnerable service, and they reproduced it and applied it to rescue the funds of exposed accounts, securing them.
We were commissioned by the Ethereum Foundation to perform an impact study of Ethereum Improvement Proposals (EIPs) 4758 and 6780 on existing contracts.
Over one-third of even the latest Ethereum smart contracts consist mostly of junk!
