Senator Warner Calls for Thorough Investigation and Accountability
Democratic Senator Mark R. Warner, Vice Chair of the Senate Select Committee on Intelligence, issued a statement expressing deep concern over the compromise of HSIN. Warner noted that for more than two decades, the HSIN platform has been used by federal, state, local, Tribal, territorial law enforcement, and private sector partners to share intelligence, plan, coordinate, and collaborate on events, and respond to incidents. Warner stated that the information in HSIN, while not classified, is highly sensitive, and its exposure risks national security. He called on DHS and the Department of Justice to thoroughly investigate who breached HSIN, what the attackers accessed, and ensure all DHS partners receive timely information and tools to mitigate associated risks. Warner further stated that DHS must account for how the breach happened and ensure it does not happen again, emphasizing the need for the homeland security community to have confidence in HSIN's security and for the American public to trust that the Department responsible for America's cybersecurity has its own house in order.
