S0688: Meteor

Meteor is a wiper that was used against Iranian government organizations, including Iranian Railways, the Ministry of Roads, and Urban Development systems, in July 2021. Meteor is likely a newer version of similar wipers called Stardust and Comet that were reportedly used by a group called "Indra" since at least 2019 against private companies in Syria.[1]

Glexia's Take

Analyst context for executives and security teams

Analyst confidence Medium

Meteor matters because it is described by ATT&CK as a Windows wiper associated with destructive activity against government and transportation-related organizations. For leaders, the defensive value is not in memorizing the malware name, but in validating whether the organization can detect and recover from the behaviors ATT&CK links to it: scheduled execution, WMI and command-shell use, Group Policy modification, security-tool impairment, log clearing, recovery inhibition, account access removal, defacement, service stopping, and data destruction.

Executive priority

Treat this as a resilience and incident-readiness use case for destructive Windows intrusions. Priority questions are: can critical Windows and Active Directory environments withstand malicious GPO changes, service disruption, account lockout/removal, and recovery inhibition; are backups and recovery paths protected from administrative misuse; and can the SOC still see activity if endpoint tools or Windows logs are tampered with? This object supports tabletop, control validation, and audit evidence around destructive malware preparedness, especially where business continuity or cyber-physical operations depend on Windows systems.

Technical view

ATT&CK provides no official detection text for Meteor, so defenders should build coverage from the related techniques. Prioritize Windows telemetry for WMI execution, PowerShell, cmd.exe, scheduled task creation or modification, suspicious task/service naming, Group Policy changes in Active Directory/SYSVOL, Windows Event Log clearing, service stops, security-tool tampering, account access changes, recovery inhibition, file deletion, and destructive file activity. Because several related technique descriptions are broader than Windows, keep validation anchored to the supplied Meteor platform: Windows.

Likely telemetry

  • Windows Security, System, Application, PowerShell, WMI-Activity, and Task Scheduler logs
  • Endpoint process creation and command-line telemetry for powershell.exe, cmd.exe, schtasks.exe, WMI providers, service-control activity, and native API-backed execution indicators
  • Active Directory and Group Policy change auditing, including GPO object changes and SYSVOL policy file modifications
  • Service creation, service stop, and service configuration change events
  • Endpoint security tool health, tamper, service status, and policy-change events

Detection direction

  • Create behavior-focused detections mapped to the related ATT&CK techniques rather than relying on a Meteor-specific signature, since official detection guidance is not provided.
  • Correlate execution paths: WMI, PowerShell, Windows command shell, scheduled tasks, and native API activity occurring near discovery, tool transfer, service stopping, or destructive file operations.
  • Tune scheduled task and service masquerading analytics against known-good administrative naming patterns; false positives are likely from legitimate IT automation and software deployment tools.
  • Alert on Group Policy changes that affect security posture, account access, service behavior, recovery settings, or endpoint tooling, especially when followed by broad endpoint changes.
  • Monitor for log clearing and security-tool degradation as high-priority visibility-loss events, not merely cleanup activity.

Mitigation priorities

  • Prioritize recoverability: maintain protected, tested backups and recovery mechanisms that cannot be altered through ordinary endpoint or domain-admin paths.
  • Harden Active Directory and Group Policy administration with least privilege, change control, monitoring, and rapid rollback procedures.
  • Restrict and monitor administrative execution channels such as WMI, PowerShell, Windows command shell, and scheduled task creation where business operations allow.
  • Protect endpoint security tools and logging pipelines against tampering, and forward critical logs off-host quickly.
  • Implement service and account change governance for critical systems, including alerting on unusual service stops and access-removal events.
Analyst notes and limits

The supplied ATT&CK object identifies Meteor as a Windows wiper and links it to multiple execution, discovery, defense-impairment, stealth, persistence/privilege-escalation, command-and-control, and impact techniques. The strongest defensive takeaway is to validate destructive-intrusion readiness across Windows endpoints and Active Directory, not to assume a single malware indicator will be available or durable.

MITRE provides no official detection section for this object, no aliases, and no object-level tactics. The description includes historical reporting and a likely relationship to Stardust and Comet, but this take does not infer current activity, attribution, or exposure. Some related technique descriptions list non-Windows platforms; because Meteor’s supplied platform is Windows, local validation should focus on Windows unless an organization has separate evidence to expand scope.
