The "flash" warning to businesses described
tools and techniques used by the hackers and asked companies to
contact federal authorities if they believe they are the victims
of such attacks.
The document said the agency recently obtained information
regarding "a group of Chinese government affiliated cyber actors
who routinely steal high-value information from U.S. commercial
and government networks through cyber espionage."
FBI spokesman Josh Campbell confirmed via email that the FBI had
released the document, which was obtained by Reuters and
described specific mitigation steps that companies should take
following attacks.
"The FBI has recently observed online intrusions that we
attribute to Chinese government affiliated actors," he said.
"Private sector security firms have also identified similar
intrusions and have released defensive information related to
those intrusions."
The Chinese embassy in Washington fired back by asking "the U.S.
side to stop this kind of unfounded accusation," echoing past
responses to U.S. allegations of government-backed cyber
security breaches.
"I’m not aware of the investigation by the U.S. FBI," Chinese
embassy spokesman Geng Shuang said. "Judging from past
experience, conclusions of this kind of investigations are
usually lacking in provable facts and hard evidence."
