BTC24H, a new ERC20 smart contract token launched on the Polygon blockchain, was compromised due to an access control vulnerability in its Lock contract. The flaw in the contract’s claim function allowed unauthorized users to claim BTC24H tokens after a specified date without verification of eligibility. This security breach led to an estimated loss of approximately $85,700 worth of tokens, as attackers exploited the vulnerability to drain the funds. The BTC24H project does not appear to have any social media or website, and it is unclear how the project is responding to the loss situation.
