WASHINGTON – Today, U.S. Sen. Mark R. Warner (D-VA), Vice Chairman of the Senate Select Committee on Intelligence and Co-Chair of the Senate Cybersecurity Caucus, issued the statement below after the Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), the Office of the Director of National Intelligence (ODNI), and the National Security Agency (NSA) released a joint statement attributing the SolarWinds hack to Russia:

“It’s unfortunate that it has taken over three weeks after the revelation of an intrusion this significant for this Administration to finally issue a tentative attribution. I would hope that we will begin to see something more definitive, along with a more public pronouncement of U.S. policy towards indiscriminate supply chain infiltrations of this sort in the future. We need to make clear to Russia that any misuse of compromised networks to produce destructive or harmful effects is unacceptable and will prompt an appropriately strong response.”
