Intelligence Summary
The Department of Homeland Security says it is investigating a cyberattack involving the Homeland Security Information Network (HSIN). HSIN is used to share sensitive information across federal, state, local, and private-sector partners. The intrusion may have exposed data or impacted how partners access and exchange information. DHS has not released detailed findings in the report. Organizations that rely on HSIN should review related access activity and watch for indicators of compromise.
Recommended Action
Inventory where Homeland Security Information Network (HSIN) runs in your environment and treat this as an active remediation item. Until then, watch authentication and outbound traffic logs for the indicators described in the source. This signal rests on a single report, so corroborate it before acting on anything irreversible.
