It posted 21 claims in the last 30 days, against 12 in the 30 days before. Small counts swing a lot and leak sites post in batches.

36% of its claims with a known country are in the United States.
BrainCipher 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.
