The Department of Homeland Security is investigating a breach of its platform, which federal, state, and local governments and law enforcement use to share intelligence, with one senior lawmaker warning that the information spill could risk national security.
News sites Nextgov, which first broke news of the incident, and Bleeping Computer report that DHS officials are probing a cyberattack on its Homeland Security Information Network, or HSIN, which allows government agencies and local officials to plan, coordinate, and share information and intelligence about major events and respond to emergencies.
