Harmony confirmed an exploit in which an attacker reportedly minted 4B ONE without authorization; ~97% of the proceeds were already moved to exchanges, elevating near-term sell pressure and liquidity stress. Efforts to freeze stolen funds may limit ultimate losses, but the incident undermines protocol security confidence and can trigger risk-off positioning across the Harmony ecosystem (tokens, dApps, and bridges).
