Note on UTA identifiers: "UTA" stands for Unattributed Threat Actor. UTA-2026-006 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

A complete AdaptixC2 operator toolkit covering the full intrusion kill chain, exposed with its team server, C2 and staging co-located on one Uzbekistan-hosted IP. A Linux build fingerprint, recovered listener configuration and a matched loader pair make the operator trackable; two APT candidates were ruled out on tradecraft.

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

No live victim traffic was captured; targeting could not be assessed.

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

Reports

Artifacts this operator chose or created: handles, channels, operator brands and domains, wallets and the like. Each is printed in a report linked above; the full indicator set, with its caveats, is in each report's IOC feed.
