G0012 Nation-stateour call,
not MITRE’s ATT&CK Group

Darkhotel

How MITRE ATT&CK characterizes this group¹: Darkhotel is a suspected South Korean threat group that has targeted victims primarily in East Asia since at least 2004. The group's name is based on cyber espionage operations conducted via hotel Internet networks against traveling executives and other select guests. Darkhotel has also conducted spearphishing campaigns and infected victims through peer-to-peer and file sharing networks.

Origin / sponsor: not established from a curated public advisory — see Coverage & confidence. Not asserted here.

Read this as · tier is our editorial call, not MITRE’s

Read as a state-directed operator, not a smash-and-grab.

A nation-state classification means patience, tradecraft, and an intelligence objective. When this name attaches to a vulnerability, the question shifts from “will someone exploit it” to “has a well-resourced service already built it into an operation.” All tradecraft below is sourced to MITRE ATT&CK.

Tradecraft heatmap

— ATT&CK techniques mapped onto the five attacker-outcome narratives

Each row is a documented technique (MITRE ATT&CK). Each column is one of the five attacker-outcome narratives a defender funds against. A filled cell means this technique’s own ATT&CK tactic defensibly advances that outcome. The mapping of technique→outcome is our editorial alignment over ATT&CK's tactic data, not a separately-sourced MITRE edge. A filled cell means one of the technique's own ATT&CK tactics defensibly advances that outcome; enabler tactics (C2, Defense Evasion, Discovery) heat no column.

Reach: this actor’s cited techniques light columns 1·2·3·4 — furthest is 4 · Data at risk. (furthest-position idiom, reused from the landing map).

A dot = this technique advances that outcomeColumn 5 (Lights out) is empty — Compare: a ransomware or wiper actor lights column 5.

Editorial: the technique→outcome alignment is our call over ATT&CK’s tactic data, not a separately-sourced MITRE edge — same basis the landing page declares. Enabler tactics (C2, defense evasion, discovery) heat no column.¹

ATT&CK lists no first-class campaign object for G0012 at this snapshot. Public reporting may tie this actor to operations; those enter only with a named advisory under the same cite-or-die rule.

snapshot

The most recent cited activity in this card is the ATT&CK record itself. We do not paste a “last seen this week” line we cannot source. Recency from secondary reporting appears here only when attached to a named advisory.

ATT&CK snapshot, compiled 2026-06-22Coverage gap — live “currently active” status not asserted

CVE ↔ actor bridge: no confirmed CVE link is established for this group. ATT&CK provides no first-class group→CVE relationship, so this card does not claim specific CVEs as “exploited by this actor” unless a named advisory says so. Absence of a CVE here is a coverage gap, never a clean bill — confirmed links surface as a cited, linked list as the advisory bridge grows.

Coverage gaps — stated, not hidden

Origin/sponsor not established from a curated public advisory. ATT&CK prose may imply attribution but is not asserted here — absence of a curated source is a coverage finding, not a clean bill of attribution.

Threat tier is OUR editorial classification (rule-based), not a MITRE field — labeled as such.

Technique → outcome heatmap is editorial alignment over ATT&CK tactic data, not a separately-sourced MITRE edge.

Activity bounds are a floor from attributed-campaign dates only — flagged approx., not a true active-since range.

ATT&CK has no first-class group→CVE relationship; this card asserts no specific CVE without a named advisory.

No attributed ATT&CK campaign object — activity bounds cannot be established.

Empty heatmap column(s): Lights out — consistent with this actor's nature, stated as a finding.
