The hackers behind the massive breach of SolarWinds’ Orion software were able to access the email accounts of top officials at the Department of Homeland Security, including those of then-Secretary Chad Wolf and members of the department’s cybersecurity staff, reports the Associated Press. “The SolarWinds hack was a victory for our foreign adversaries, and a failure for DHS,” remarked Senator Rob Portman (R-OH), ranking member of the Senate Homeland Security and Governmental Affairs Committee. “We are talking about DHS’s crown jewels.”

During interviews with numerous current and former U.S. government officials, AP learned new details about the breach of DHS’s systems, and that hackers also accessed the private calendars of top Department of Energy officials, including then-Secretary Dan Brouillette.
