The conservative Washington Free Beacon reported on Sunday that hackers linked to the Chinese government had breached the White House Military Office.
The White House would not say if the attack originated in China, describing it as a “spear-phishing” attempt.
“Spear-phishing” typically works by sending fake e-mails that look like legitimate correspondence, but which link to a malicious website or file attachment.
“These types of attacks are not infrequent and we have mitigation measures in place,” the official, who was not authorised to speak on the record, told the Associated Press and other US media.
Cyber-attacks from Chinese-linked hackers have been an increasing concern among US government offices, including the Pentagon, the head of intelligence for US cyber defence told Reuters last week. – BBC
