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.
Names are analytic constructs
Current activity
Recently reported OT threat activity
A human-reviewed digest, not a live feed. Each entry links to the public reporting it summarises.
Joint government advisory detailed persistent pre-positioning in US critical infrastructure using living-off-the-land techniques.

26 publicly reported activity groups
Filter by activity, OT capability or sector. Search matches vendor aliases too — try “Volt Typhoon”, “APT44” or “PIPEDREAM”.
VOLTZITE
activeDragos · 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
activeDragos · 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
activeDragos · 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
XENOTIME
unknownDragos · 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
CHERNOVITE
unknownDragos · 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
BAUXITE
activeDragos · 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
AZURITE
activeDragos · 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
SYLVANITE
activeDragos · 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
GRAPHITE
activeDragos · 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
PYROXENE
activeDragos · 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.
No publicly associated names established
KOSTOVITE
activeDragos · 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.
No publicly associated names established
HEXANE
activeDragos · 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.
Also reported as OilRig-adjacent reporting, Lyceum
ALLANITE
activeDragos · OT-focused access
ALLANITE is reported for access operations against electric utilities in the United States and United Kingdom, including collection of information from business and operations networks. Public reporting emphasises reconnaissance and access rather than demonstrated ICS effects.
Also reported as Palmetto Fusion / Dragonfly-adjacent reporting
CHRYSENE
activeDragos · IT access with OT relevance
CHRYSENE is reported for operations against petrochemical, oil and gas and electricity generation organisations, with public reporting describing a relationship to the tooling ecosystem associated with the Shamoon-era wiper activity. Reported activity is focused on IT-side access into organisations that run industrial processes.
Also reported as OilRig / Greenbug-adjacent reporting
DYMALLOY
activeDragos · OT-focused access
DYMALLOY is reported for deep and long-lived access into electric utilities, oil and gas, and advanced industrial organisations, including access to operator interfaces. Public reporting describes overlap with the widely reported Dragonfly / Energetic Bear activity.
Also reported as Dragonfly / Berserk Bear / Energetic Bear
MAGNALLIUM
activeDragos · IT access with OT relevance
MAGNALLIUM is reported for targeting oil and gas and aerospace organisations, with public reporting describing overlap with activity other vendors track as APT33. Reported operations focus on enterprise access at organisations that operate industrial processes.
Also reported as APT33, Peach Sandstorm
PARISITE
activeDragos · IT access with OT relevance
PARISITE is reported for exploiting known vulnerabilities in VPN appliances to gain access to aerospace, oil and gas, government and utility organisations, and for providing that access to other operations.
Also reported as Iran-linked access operations reported by multiple vendors
PETROVITE
activeDragos · IT access with OT relevance
PETROVITE is reported for targeting mining and energy operations, primarily through reconnaissance and information collection about operational environments rather than demonstrated ICS effects.
No publicly associated names established
RASPITE
unknownDragos · IT access with OT relevance
RASPITE is reported for reconnaissance and access operations against electric utilities, including credential-theft techniques delivered through compromised websites. Reported activity is access-focused, with no publicly demonstrated ICS capability.
Also reported as LeafMiner-adjacent reporting
STIBNITE
unknownDragos · IT access with OT relevance
STIBNITE is reported for targeting wind generation and electric utility organisations in North Africa, using credential-theft websites and phishing to gain access to operational organisations.
No publicly associated names established
TALONITE
unknownDragos · IT access with OT relevance

No publicly associated names established
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.
