Threats · Activity groups

One adversary. Many names.

A cross-reference for publicly tracked threat groups affecting operational technology and critical infrastructure — connecting vendor names, activity clusters, campaigns, malware, techniques, industries, and reported OT impact.

Registry last reviewed

Names are analytic constructs

Threat-group names are analytic constructs. Different organizations may track overlapping but nonidentical activity under different names. “Associated” does not always mean “identical.” Every relationship on this site is labelled with the kind of link the source supports.

VOLTZITE

active

Dragos · OT-focused access

VOLTZITE is the Dragos activity group tracking intrusions into US critical infrastructure that overlap heavily with the activity governments and vendors report as Volt Typhoon. The defining characteristic is patience: long-dwell access obtained through internet-facing edge devices, maintained almost entirely with living-off-the-land techniques, and used to collect information about operational technology rather than to cause an immediate effect.

Also reported as Volt Typhoon, BRONZE SILHOUETTE, Vanguard Panda +4

ELECTRUM

active

Dragos · Stage 2 ICS effects

ELECTRUM is the Dragos activity group associated with ICS-capable operations against the Ukrainian electric sector, including the 2016 Kyiv transmission substation event and later attempts using updated Industroyer capability. It is the cluster that demonstrably possesses and has deployed malware able to speak electric-sector protocols directly to field equipment.

Also reported as Sandworm Team, APT44, Seashell Blizzard +6

KAMACITE

active

Dragos · IT access with OT relevance

KAMACITE is the Dragos activity group focused on gaining and maintaining access to industrial organisations — phishing, credential theft and initial-access operations — with reported operational relationships to ICS-effects activity carried out by ELECTRUM.

Also reported as ELECTRUM, Sandworm-associated activity, BlackEnergy operations

Attribution · Moderate

XENOTIME

unknown

Dragos · Stage 2 ICS effects

XENOTIME is the Dragos activity group associated with the TRITON / TRISIS intrusion, in which malware was written to interact with Schneider Electric Triconex safety instrumented systems at a petrochemical facility. It is the only publicly reported activity group whose capability was aimed directly at a safety instrumented system.

Also reported as TEMP.Veles, TRITON / TRISIS, HatMan

Attribution · High

CHERNOVITE

unknown

Dragos · Stage 2 ICS effects

CHERNOVITE is the Dragos activity group credited with developing PIPEDREAM, the modular ICS attack framework discovered before deployment. PIPEDREAM is capability, not an actor: it is the toolset, and CHERNOVITE is the cluster that built it. Conflating the two is the single most common naming error in OT threat intelligence.

Also reported as PIPEDREAM, INCONTROLLER

Attribution · Moderate

BAUXITE

active

Dragos · OT-focused access

BAUXITE is the Dragos activity group associated with attacks on internet-exposed industrial devices across water, energy and manufacturing. Public reporting describes technical overlap with the hacktivist-branded persona CyberAv3ngers, which CISA and partner agencies have linked to IRGC-affiliated actors.

Also reported as CyberAv3ngers

Attribution · Moderate

AZURITE

active

Dragos · OT-focused access

AZURITE is a Dragos activity group reported for interest in engineering workstations and the operational data held on them — controller configuration, HMI screens, alarm lists and process documentation. The pattern is collection rather than immediate effect, but the material collected is exactly what an actor would need to build a targeted capability later.

Also reported as Flax Typhoon, Ethereal Panda, UNC5923 +2

Attribution · Moderate

SYLVANITE

active

Dragos · IT access with OT relevance

SYLVANITE is reported as an access-development cluster: it specialises in compromising internet-facing edge infrastructure, rapidly weaponising newly disclosed vulnerabilities, and establishing footholds that other operations then use. Public reporting describes handoff of that access to VOLTZITE follow-on activity.

Also reported as VOLTZITE

Attribution · Moderate

GRAPHITE

active

Dragos · IT access with OT relevance

GRAPHITE is a Dragos activity group targeting energy, oil and gas, logistics and government organisations, with public reporting describing technical overlap with the actor widely tracked as APT28. The overlap is technical and analytic — it is not presented here as a direct alias.

Also reported as APT28, Forest Blizzard

Attribution · Moderate

PYROXENE

active

Dragos · IT access with OT relevance

PYROXENE is a more recently named Dragos activity cluster reported against industrial and critical-infrastructure organisations. Public technical reporting remains limited relative to older clusters, and this profile deliberately separates what is technically evidenced from what is geopolitical assessment.

KOSTOVITE

active

Dragos · OT-focused access

KOSTOVITE is reported for compromising remote-access infrastructure at energy organisations and operating almost entirely with living-off-the-land techniques once inside, including reaching OT networks through the same remote-access path legitimate engineers use.

HEXANE

active

Dragos · IT access with OT relevance

HEXANE is reported for targeting oil and gas and telecommunications organisations, with public reporting describing overlap with activity other vendors track as an Iran-linked cluster. Reported tradecraft is largely IT-side: phishing, credential theft and access to organisations that operate industrial processes.

Why should I care?

An advisory naming “Volt Typhoon”, a vendor report naming “VOLTZITE” and an internal ticket naming “BRONZE SILHOUETTE” can all describe the same problem in your environment. Reconciling them is what turns three disconnected reports into one defensive priority.
