Recently, Anzen Finance, a provider of RWA stablecoins, experienced a major attack resulting in a loss of $500,000. The cause of this incident was a decimal error between the blast and base chains, which allowed the attacker to exploit the vulnerability for theft. However, through concerted efforts, a white-hat hacker from the YAM community successfully identified the attacker's identity. After paying a $50,000 bounty to the white-hat hacker, the hacker was persuaded to return $450,000 of the funds. This event serves as a reminder to participants in the cryptocurrency industry of the critical importance of enhancing security awareness and technical protection.
