On Aug 4th, 2021, Popsicle Finance, a multi-chain revenue optimization platform, suffered a huge financial loss (over $20M) from an attack through its Popsicle LP token (PLP for short) liquidity pool. After manual analysis, BlockSecTeam confirm that it is a double-claiming attack, i.e., a loophole of its reward system allows the attacker to claim rewards repeatedly. The core of this vulnerability is that the same PLP certificate can bring benefits to multiple holders at the same time node due to the defect in the reward update record. Equating to the real world scenario, it means a user deposits money to a bank and the bank gives her a certificate of the deposit. Unfortunately, this certificate is neither anti-counterfeiting, nor associated with the user. In such a case, it is possible to make duplicates and spread them to others to gain profits from the bank.
