Microsoft president Brad Smith on "real concern" about Chinese malware targeting critical infrastructure

A Chinese-sponsored hacking campaign targeting critical infrastructure in Guam and other locations within the United States is "of real concern," Microsoft president Brad Smith warned. 

Microsoft revealed the hacking operation, code-named "Volt Typhoon," on Wednesday, saying it could disrupt communications between the U.S. and Asia during a future potential conflict. The operation has been active for about two years. 

"What we found was what we think of as network intrusions, the prepositioning of code. It's something that we've seen in terms of activity before," Smith said in an interview with "Face the Nation." "This does represent the focus on critical infrastructure in particular, and that's obviously of real concern."
