G0055 Unknownour call,
not MITRE’s ATT&CK Group

NEODYMIUM

How MITRE ATT&CK characterizes this group¹: NEODYMIUM is an activity group that conducted a campaign in May 2016 and has heavily targeted Turkish victims. The group has demonstrated similarity to another activity group called PROMETHIUM due to overlapping victim and campaign characteristics. NEODYMIUM is reportedly associated closely with BlackOasis operations, but evidence that the group names are aliases has not been identified.

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

Motivation not classified from the public record.

We could not place this actor into a coarse motivation tier from ATT&CK’s intrusion-set type and description prose. That uncertainty is itself a finding — the tradecraft below is still cited; the “why” is a coverage gap. All tradecraft below is sourced to MITRE ATT&CK.

No techniques are recorded for this group in the ATT&CK snapshot below — the tradecraft heatmap is empty. That is an honest coverage gap (sparse / legacy / revoked group), never a claim that the actor does nothing.¹

Stated, not hidden

ATT&CK lists no first-class campaign object for G0055 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.

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 techniques attributed to this group in ATT&CK — a real source coverage gap, surfaced honestly, never fabricated.

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