▪

Read, Watch or Listen

The U.S. Department of Homeland Security is investigating an intrusion into the Homeland Security Information Network (HSIN), a central information‑sharing system used by federal, state, local and international partners. According to individuals familiar with the matter, hackers accessed HSIN servers and an associated SharePoint collaboration system between late May and early June 2026. The compromised platform carries sensitive but unclassified data used for real‑time communication, document sharing, alerts and incident management. Officials are conducting a damage assessment to determine what material may have been accessed, while the breach draws added scrutiny because the United States is currently managing security operations for World Cup events nationwide.
