Chinese hacking against US rising in recent months: intelligence official

Joyce, a former White House cyber advisor for president Donald Trump, did not elaborate or provide an explanation of what he meant by critical infrastructure.

A senior US intelligence official warned that Chinese cyber activity in the United States had risen in recent months, and the targeting of critical infrastructure in such operations suggested an attempt to lay the groundwork for future disruptive attacks.

”You worry they are prepositioning against critical infrastructure and trying to be able to do the types of disruptive operations that would be the most concern,” National Security Agency official Rob Joyce said in response to a question about Chinese hacking at a Wall Street Journal conference.
