How Someone Tried to Exploit a Flaw in Our Smart Contract and Steal All of Its Ether

[/vc_column_text][vc_column_text el_class=”topfeed-summary-list”]

  • The weird transactions can be observed in the Internal Transactions tab of the CityMayor contract.
  • The execution seems to trigger the execution of the CityMayor contract (we can see that in the internal transaction tab again) and sends it the attackers 0.25 ETH.
  • Our attacker calls the function of his/her malicious contract, which seems to trigger the function of CityMayor.
  • CityMayor reimburses the attackers contract by sending it the 0.25 ETH but the transaction fails.
  • Whats even more interesting, is that this fallback function could call the CityMayor contract again.
