What the data says
Chaos ranks #79 of the 122 groups profiled here, with 54 claimed victims (0.2% of all claims we track).
Its earliest reliably dated claim in our data is 14 April 2026; the latest is 3 November 2026.
It posted 2 claims in the last 30 days, against 9 in the 30 days before. Small counts swing a lot and leak sites post in batches.
Its claims lean toward Healthcare: 19% of its sector-labelled claims, against 10% across all groups (1.8× the usual share).
66% of its claims with a known country are in the United States.
Chaos activity, last 24 months
Claims per month, by the date our trackers first saw them, so batches can land late. We have almost no collection from June 2025 to March 2026: an empty stretch there means we weren't looking, not that the group was idle. The current month is partial.
Regions targeted
Sectors targeted
