Foresight News reports that SlowMist Security Team has released an analysis report on the Truebit Protocol security incident. On January 8, Truebit Protocol was attacked due to an integer overflow vulnerability in its Purchase contract. The attacker was able to mint TRU tokens at nearly zero cost and stole 8,535 Ethereum (approximately $26.44 million). The root cause was the lack of overflow protection mechanisms in the contract, leading to incorrect price calculations. The stolen funds were subsequently transferred to Tornado Cash. It is recommended to always use SafeMath to protect all arithmetic operations in contracts compiled with Solidity versions prior to 0.8.0 to prevent overflow-related logical flaws.
