This is a defensive tool-intelligence page. It is intended for analyst navigation, source review, and hunt planning. It is not a malware-analysis report and does not contain sample code or binaries.

Summary

• Associated actor(s): UNC1860
• Tool type(s): Associated family
• Confidence level(s): Medium
• Source ID(s): SRC-MALPEDIA-UNC1860

Behavior

Actor	Behavior Summary
UNC1860	Malpedia lists win.cryptoslay as an associated UNC1860 family and ties the reference set to Mandiant's UNC1860 reporting.

Hash And IOC Status

Actor	Status	Reference
UNC1860	Family confirmed by Malpedia; no per-sample hash committed in this repo.	SRC-MALPEDIA-UNC1860

Hashes and IOCs on this page are source pointers or representative public indicators. They SHOULD be refreshed from the linked source before operational use and MUST NOT be used alone for actor attribution.

Defensive Hunting Notes

Actor	Hunting Notes
UNC1860	Use as taxonomy enrichment; do not create production detections until behavior is tied to a primary source or sample-level report.

Handling Notes

Actor	Handling Notes
UNC1860	Malpedia taxonomy confirms association; behavior remains source-gated.

Related Actor-Level Repository Detections

These detections are mapped through the associated actor or scenario and are not automatically tool-specific. Promote a tool-specific detection only after the behavior is tied to telemetry and test evidence.

Actor	Detection	Release Status	DRL	Rule
UNC1860	DET-003 - Unitronics PLC HMI Web Interface Access	Hunt	4	detections/sigma/unitronics-plc-hmi-web-access.yml

Related Actor-Level Hunts

These hunts are mapped through the associated actor or scenario and may need narrowing before they are used for this specific tool.

Actor	Hunt	Hypothesis	Query
UNC1860	HUNT-003	If exposed PLC/HMI surfaces are targeted then OT management paths or ports will show external access	detections/sigma/unitronics-plc-hmi-web-access.yml
