Note on UTA identifiers: "UTA" stands for Unattributed Threat Actor. UTA-2026-010 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 customer-side operator of a commodity infostealer, identified by a homebrew loader with zero-public-hit strings, an unusual key length and a hollowing target no other documented customer uses, calling back to a C2 that stayed stable for almost three years and outlived a law-enforcement takedown. The stealer's vendor is a separate, well-documented target and is explicitly outside this designation.

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.
