The Hong Kong Monetary Authority (HKMA) has issued a warning about fraudulent websites impersonating its official site to deceive the public into conducting cryptocurrency transactions. These scam sites use the HKMA logo and claim to require payments for 'taxes' or 'account unlocking' to steal funds. The HKMA clarified that these sites have no affiliation with the official authority and do not contact individuals for transactions or account verifications. The HKMA has reported the matter to the police and advises the public to avoid suspicious links and verify financial investment information to prevent fraud.
