According to ChainCatcher, Singaporean angel investor Mark Koh has fallen victim to a phishing scam, resulting in the loss of cryptocurrency assets valued at at least 100,000 yuan. Koh, an early investor in the blockchain platform Polygon, has been involved in the Web3 sector since 2017. The incident occurred when Koh encountered a post about the game project 'MetaToy' in a Telegram group. A user named Shanni, claiming to be the co-founder of the 'Meta team,' contacted him and requested the download of a game launcher. Upon downloading, malware infiltrated his system and stole data from his crypto wallet. Despite conducting a full system scan and reinstalling his system, Koh discovered that multiple electronic wallets connected to browser extensions were emptied within 24 hours. Koh suspects that the scammers used the name of a legitimate game project to plant malware on a fake website. Ironically, Koh is the co-founder of 'RektSurvivor,' an organization dedicated to assisting victims of cryptocurrency scams, yet he now finds himself a victim. He reported the incident to the authorities on the 12th and has urged the public to avoid downloading software from unknown sources and to refrain from sharing mnemonic phrases and two-factor authentication information.
