    Requests for files that exist only to be stolen - .env, .git internals, configuration and database backups. A web sensor reports this after several distinct such paths from one address, never after a single 404.

Correlation2 multi-signal, 10 single-signal

Addresses sharing an observed attribute with this one. Arrival proximity uses a ±30 minute window around first observation.

Showing the 12 strongest of 220 related addresses, ranked by how much each shared value narrows the field.

These are shared observations, not attribution. Abuse Radar does not claim common ownership, operation, coordination or intent between these addresses.

Abuse Radar publishes sanitized indicators only. Severity is a triage hint computed from detection volume, sensor corroboration, signal class and recency — it is not an attribution claim. See methodology.
