Singapore-based angel investor Mark Koh lost over $100,000 in cryptocurrency due to a phishing scam on December 5, 2025. The incident occurred when Koh, while testing a video game, was contacted via Telegram by an individual impersonating a MetaToy co-founder. After downloading a game launcher, his crypto wallet was compromised, leading to the loss of funds within 24 hours. Koh has reported the scam and cautioned others against downloading unverified software and emphasized the importance of safeguarding recovery phrases and two-factor authentication codes.
