Which companies just had a verified incident, who lends to them and who owns them. Every claim carries its evidence level and its source. How we decide what is confirmed
US Critical Infrastructure Cyber Intelligence
Early warning, active monitoring, verified incidents and infrastructure dependencies. Provider status posts are shown as what the provider published; only analyst-reviewed findings are called cyber incidents.
Coverage is reduced: DFX is not reading 105 of 124 status feeds, because their robots.txt does not allow it or could not be read, while we move to the incident feeds providers publish.
Filtered to all sectors, CO. Clear filters
Where the findings are
Shaded by the number of public findings in each state. A filled marker means the finding documents a site in that state; a ring means it is placed by headquarters only, which says nothing about the area around it. Select a state to filter the page.
Confirmed cyber incidents
Incidents confirmed by the organisation, a regulator or compelling corroborated evidence, reviewed by an analyst. Live provider posts never enter this list on their own.

Emerging operational signals
What providers published on their own status pages in this window, with the kind of wording they used. A disruption, a restriction or even security language is a provider statement, not a DFX finding that an attack occurred.
