Dark Angels

Aliases: Dark Angels ransomware, Dunghill Leak

Source profile review date: 2026-06-21

Added to the source registry: Date unknown · Source snapshot: 2026-09-15

Source metadata is not independently verified. The registry date is not necessarily the first attack date. Source synopses are translated automatically where needed; the feed may contain outdated assessments.

Research status: Existing researched dossier

This dossier separates actor-specific source information from general defensive analysis. Recommendations and investigation questions are not additional claims about the actor. Public evidence remains limited where explicitly stated.

Executive summary

Dark Angels is known for highly targeted big-game extortion and sometimes quiet negotiations without broad publicity.

Dark Angels is seen in public CTI as a group that selectively approaches large organisations and uses data extortion. The group is also linked to Dunghill Leak.

    These are public claims attributed to the group, not independently confirmed breaches. Dates indicate publication or discovery, not necessarily the attack date.

    Executive summary

    Dark Angels is relevant because the pattern revolves around high data volumes, selective victims, exfiltration and pressure around confidentiality. Encryption is not always the only or most important issue.

    The focus is on what can be defended: initial access, identity, lateral movement, data access, exfiltration, encryption and recoverability. A group name becomes useful only when translated into concrete controls.

    For groups with less hard public technical reporting, confidence is lower. The profile is then used as a scenario based on known patterns, not as absolute technical attribution.

    Group and development

    Dunghill or leak-site claims, proof data, large data transfers, archives and communication with extortionists are core artefacts.

    Ransomware brands change quickly. Affiliates, code, leak sites and access brokers can change names while the underlying playbook remains recognisable.

    This profile is kept when the name appears in feeds and has defensive value.

    Attack pattern from public cases

    Victims are attractive when one incident creates very high data risk and reputational pressure.

    Most attacks become visible only at a claim, ransom note or encryption. Earlier phases matter more for prevention: suspicious login, discovery, archiving, outbound transfer and abuse of administrative rights.

    Technical conclusions must always be tied to internal telemetry: logs, process trees, command lines, accounts, file locations and network connections.

    Known IOCs and artefacts

    Detect bulk export from crown-jewel data, privileged-account access to many repositories and long-running staging.

    Hard IOCs are useful for retro-hunting, but age quickly. Behavioural indicators such as remote access, RMM tooling, data staging, service stops and mass file writes remain useful longer.

    Record indicators per incident with source, date, confidence and incident phase.

    Victim pattern and lessons

    Strictly limit data access, monitor large exports and define leadership decision-making around data extortion in advance.

    Use victim patterns as risk scenarios. Sector, data types, dependency on systems and recovery capacity determine extortion pressure.

    A claim at a comparable organisation should trigger checks of your own access routes, data exposure and recoverability.

    Practical detection logic

    Use Dark Angels reporting as context, but validate claims with local telemetry and incident-specific artefacts.

    Look for chains instead of isolated events. A suspicious VPN login plus share discovery plus archiving plus outbound traffic is much stronger than a single alert.

    Check endpoints, file servers, cloud storage, backup platforms, hypervisors and RMM tools.

    Concrete hardening priorities

    Treat Dark Angels primarily as a targeted data-extortion scenario focused on confidentiality pressure.

    Enforce MFA on external access, restrict RDP, segment servers, use separate privileged accounts and monitor bulk data actions.

    Protect backups and virtualisation outside the ordinary domain administration layer.

    Identity, naming and attribution

    For Dark Angels, the operational starting point is an exact identity match. The local dossier records the following names or aliases: Dark Angels ransomware, Dunghill Leak. An alias is a search aid, not independent evidence of shared operators. Similar names, reused logos and the same extortion vocabulary cannot establish a relationship between groups. Analysts should retain the original spelling of a claim and distinguish the publisher, malware family and suspected intrusion operator. Those roles can belong to different people. This prevents an incident being assigned to the wrong group simply because a filename or public post resembles an earlier case. Any proposed relationship needs its own dated, attributable source.

    Timeline and interpretation of dates

    The source registry date available for Dark Angels is Date unknown; the metadata snapshot was collected on 2026-09-15. These timestamps describe the available record, not a proven beginning of criminal operations. Registration may follow earlier activity, and a claim can concern an older incident. A defensible timeline separates suspected intrusion, data access, discovery by the victim, publication by the claimant and discovery by the monitoring service. The profile review date is another independent timestamp. Analysts should not silently convert one date into another. When sources disagree, preserve both observations and their provenance, then explain the uncertainty rather than presenting a falsely precise attack chronology.

    Victim claims and targeting assessment

    The victim panel for Dark Angels shows up to five distinct organisations from the stored claim history. It is a moving observation window, not a complete incident census. Public listings can omit victims, repeat old material or exaggerate access. Consequently, a short run of organisations in one country or industry does not by itself prove deliberate targeting of that sector. The useful comparison is with the organisation's own dependencies: shared providers, remote access arrangements, exposed services and sensitive data flows. A supplier appearing in a claim justifies verification through established contacts, but does not establish that downstream customers were compromised. Separate confirmed statements from the claimant's assertions.

    Evidence quality and confidence

    The source material listed for Dark Angels should be evaluated observation by observation. A technical report can substantiate a specific sample or incident without proving that every affiliate uses the same method. A leak-site description provides a different kind of evidence: it documents a public assertion, not the underlying access. Keep quotations, analyst interpretations and direct telemetry separate in working notes. Record which conclusion would change if a source were withdrawn or corrected. Confidence should follow the quality and independence of the evidence, not the prominence of the group name. Missing technical reporting is an intelligence gap; it is neither proof of sophisticated tradecraft nor proof that the actor is harmless.

    Indicators of compromise (IOCs)

    Indicators are historical observations, not proof of a current infection. Validate source, age and context before hunting or blocking; legitimate administrative tools can produce false positives.

    Evidence and limitations

    Attribution describes the source assessment, not a verified identity. A leak-site listing alone does not prove encryption, data theft, a particular vulnerability or an affiliate relationship. Missing information is left explicit.
