G0056 Nation-stateour call,
not MITRE’s ATT&CK Group

PROMETHIUM

How MITRE ATT&CK characterizes this group¹: PROMETHIUM is an activity group focused on espionage that has been active since at least 2012. The group has conducted operations globally with a heavy emphasis on Turkish targets. PROMETHIUM has demonstrated similarity to another activity group called NEODYMIUM due to overlapping victim and campaign characteristics.

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

Also tracked as: StrongPity — ATT&CK group page¹

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.

ReachFurthest outcome. This actor's cited tradecraft reaches as far as outcome 2 — Keys to the kingdom — privilege/identity takeover. (editorial mapping over ATT&CK tactics).

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 — furthest is 2 · Keys to the kingdom. (furthest-position idiom, reused from the landing map).

A dot = this technique advances that outcomeColumn 3 (Lateral reach) is empty — Compare: a hands-on-keyboard intruder lights column 3.Column 4 (Data at risk) is empty — Compare: an espionage / data-theft actor lights column 4.Column 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

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.

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