Source Attribution

ThreatActor.info is a research index built from public, attributed sources plus analyst-reviewed enrichment. This page summarizes the source families used by the site, how we use them, and where source-specific attribution appears.

How attribution is handled

Source inventory

Source How it is used Attribution and license notes
MITRE ATT&CK (STIX data) Group descriptions; ATT&CK IDs; technique/tactic/campaign/mitigation/software pages and actor relationships (ttps, software, campaigns); optional denormalized attck_techniques / attck_software / attck_references for APIs. MITRE permission notice appears on affected pages and in structured actor metadata for records imported from STIX.
abuse.ch ThreatFox Recent community IOC snapshots merged into existing actors when malware names or tags match (provenance.threatfox). ThreatFox data is attributed to abuse.ch; use is subject to abuse.ch terms and fair-use expectations for the community API.
MISP Galaxy Threat actor identities, aliases, descriptions, references, and relationship context. Imported MISP Galaxy records are marked as sourced from the MISP Galaxy threat-actor cluster and treated as CC0 licensed where that source metadata is present.
RansomLook and RansomLook repository Ransomware group names, aliases, descriptions, and reference-backed enrichment. RansomLook-derived data is attributed as RansomLook and marked CC BY 4.0 with the Creative Commons license URL in structured source metadata.
Malpedia by Fraunhofer FKIE Malware-family metadata and actor relationship enrichment. Malpedia-derived metadata is attributed to Malpedia/Fraunhofer FKIE and carries the Malpedia legal URL and CC BY-NC-SA 3.0 license metadata when imported.
ETDA / ThaiCERT Threat Group Cards Threat group cards, aliases, malware, operations, and timeline hints. Imported ETDA/ThaiCERT data is attributed as derived from the public Threat Group Cards and adapted for research enrichment.
tropChaud Categorized Adversary TTPs Offline snapshot under data/imports/categorized-adversary-ttps/; merged MITRE group–technique links with ETDA pivot metadata (victim industry/country, motivation). Powers /api/categorized_* JSON and /categorized-adversary-ttps/. MIT-licensed dataset; upstream merges MITRE ATT&CK (see MITRE permission notice) and ETDA Threat Group Cards (copyright ETDA as cited upstream). Attribution text appears on the pivots page and matching actor panels.
APTnotes Report-index provenance, source links, and chronology hints. APTnotes is used as a report index; copyright in linked reports remains with the original publishers.
APT Groups & Operations Alias, operation, malware, and report crosswalk enrichment. The public spreadsheet is attributed as a secondary research aid and crosswalk, not as a sole authoritative source.
CISA Known Exploited Vulnerabilities Catalog Known-exploited vulnerability context linked to selected actor pages. CISA KEV is attributed as a public government catalog; KEV entries are treated as vulnerability context, not as standalone actor attribution.
BushidoToken Breach Report Collection Reviewed breach-report links for existing actors. The collection is attributed as a report index; linked reports remain owned by their original publishers.
BushidoUK Ransomware Tool Matrix Reviewed ransomware tradecraft and tool observations for existing actors. The matrix is attributed as a secondary ransomware tradecraft reference, not sole attribution evidence.
BushidoUK Ransomware Vulnerability Matrix Reviewed CVE and exploitation observations for existing ransomware actors. The matrix is attributed as a secondary exploitation reference, not sole attribution evidence.
BushidoUK Russian APT Tool Matrix Reviewed Russian APT tool observations for existing actors. The matrix is attributed as a secondary Russian APT tradecraft reference, not sole attribution evidence.
Curated Intelligence MOVEit Transfer Tracking CL0P/MOVEit campaign event timeline enrichment. The tracking repository is attributed for event collection; linked reports remain owned by their original publishers.
BreachHQ Threat Actors Snapshot-backed secondary actor index used for reviewed name/alias matching and cross-source triage. BreachHQ data is attributed to Beyond Identity; this project treats it as a secondary reference index and preserves source provenance rather than sole attribution evidence.
EternalLiberty Alias cross-reference enrichment. EternalLiberty is attributed as a secondary alias crosswalk, not a sole authoritative source.
Analyst notes and manual entries Temporary coverage for subjects not yet covered by automated public sources. Manual entries are labeled as analyst notes or manual curation and should be superseded when a reviewed automated source becomes available.
Security news and reference fetchers Optional article/reference discovery utilities, including MISP references and security news feeds. These utilities collect links and summaries for review; source publishers retain ownership of their articles and reports.
