According to the Korean newspaper Chosun Ilbo, the South Korean National Tax Agency is accelerating preparations for the 2027 virtual asset taxation, including the establishment of a new digital asset comprehensive department and the construction of a virtual asset comprehensive analysis system. The 50000 person joint petition in Congress to abolish the virtual asset tax has not yet been put on the agenda, and discussions are stalled. The current tax system stipulates that virtual asset investment income is subject to a 22% tax after deducting 2.5 million Korean won, and virtual asset losses cannot be offset across years. The relevant discussions are expected to advance after the government's tax reform plan is announced at the end of July.

According to SlowMist Monitoring, the decentralized tipping protocol Drips Network was attacked, resulting in a loss of approximately 24900 DAIs. Slow fog analysis shows that the root cause of the attack lies in the integer type conversion defect of the give (address, uint128) function in the DaiDripsHub contract. This function converts the amount of uint128 type to int128 type without verifying whether the input parameter exceeds the maximum value of int128. The attacker passes in a specific value outside the int128 range, causing the converted amount to become negative, resulting in the transfer direction being reversed. The reserve contract executes abnormal withdrawals to the attacker's account, ultimately leading to the depletion of reserve funds.
