A portion of the Department of Defence’s nonclassified email network used by Army General Martin Dempsey and other members of the U.S. military’s Joint Staff has been shuttered after “suspicious activity” was detected on the systems over the weekend.
“We continue to identify and mitigate cybersecurity risks across our networks,” Lieutenant Colonel Valerie Henderson said. “With those goals in mind, we have taken the Joint Staff network down and continue to investigate.”
The Pentagon has not released details of the nature of the event being investigated, but did confirm that the shutdown was initiated by the DoD and was not the result of malicious activity directly.
