Note on UTA identifiers: "UTA" stands for Unattributed Threat Actor. UTA-2026-017 is a tracking label The Hunters Ledger assigns to an actor I have observed but cannot yet link to a publicly named threat group. Other vendors and feeds will not use this label; it is specific to this publication. If later evidence ties the activity to a named actor, I will retire the label and update the report.

Summary

The lower-OPSEC customer of the same kit, separated from the kit author by a per-customer configuration delta and from the sibling customer by distinct wallets and public pools. The host was abandoned days after public disclosure and its earnings were never withdrawn, for reasons the report leaves unresolved.

The confidence levels above are the published report's figures. Every claim on this page is a summary of the linked reports, which remain the record.

Targeting

Targeting is given as region and sector, drawn from the reports. Victim names are deliberately not published here or in the reports.
