Taiwan says China behind cyberattacks on government agencies, e-mails

Democratic Taiwan has been urging its people to be alert for what officials call "omnipresent infiltration" from China, involving from Beijing-backed media campaigns to cyberattacks, against the island that China considers its territory.

"Chinese hacking groups have been infiltrating government agencies and their information service providers for a long time," said the deputy director of the Taiwan Investigation Bureau's Cyber Security Investigation Office, Liu Chia-zung.

"They were aiming to acquire important government documents and data," Liu told reporters. "Some government data might have been leaked. This has posed a great threat."

The attacks, which started as early as 2018, targeted at least 10 government agencies and the email accounts of some 6,000 officials, Liu's office said, adding it had not been able to identify what data has been stolen as the hackers had concealed their tracks.

Among those who were attacked and infiltrated by two Chinese hacking groups were at least four Taiwan tech companies that had been providing information services to the government, the office said.

China's Taiwan Affairs Office did not respond to a request for comment. The Chinese government routinely denies involvement in hacking and says it punishes those who do it.

Liu said Taiwan believed the two hacking groups involved, Blacktech and Taidoor, were backed by the Chinese Communist Party. They targeted loopholes in the systems provided by the Taiwan government's information service providers, he said.

Government agencies should increase scrutiny of their providers, Liu said.

He said his office was investigating service supply chains to see if any Taiwan companies or individuals have worked with the Chinese hackers.

News of the hacking comes during a period of heightened tension between the island and China.
