The Financial Supervisory Commission (FSC) issued a warning on Saturday over the recent proliferation of "phishing" scams.
The commission reminded users of online banking services to check their bank's Web site address before engaging in any transactions or information exchanges in order to protect themselves from being "phished" by cyber-criminals.
The FSC's warning came after the technology crimes prevention and control center of the Criminal Investigation Bureau (CIB) revealed it had recently discovered that some computer hackers from China have been acquiring online banking users' personal information, such as bank account numbers and passwords, through false bank Web sites.
Anti-technology crime police officers said that "phishers" copy Web site pages of legitimate banks to trick users into disclosing sensitive personal information.
People who do not have the habit of checking the official Web site address of their banks could easily be cheated as the false bank Web sites look almost identical to the real ones, the police said.
The CIB said that in addition to personal information of bank clients, "phishers" have also been found to steal money from bank accounts online by cooperating with criminal rings in Taiwan.
The FSC called for the public to be on alert against this new type of online fraud and to avoid communicating by e-mail with any banks or other businesses with which they are not familiar.
People should always check information on exchanges through their online bank accounts and contact their bank at once if they suspect that their bank accounts and passwords have been used without their authorization, the FSC said.
