DC0073: Instance Modification
Changes made to a virtual machine (VM) or compute instance, including alterations to its configuration, metadata, attached policies, or operational state. Such modifications can include updating metadata, attaching or detaching resource policies, resizing instances, or modifying network configurations. Examples:
- AWS: instance modifications include API actions like `ModifyInstanceAttribute`, `ModifyInstanceMetadataOptions`, or `RebootInstances`. - Azure: modifications can be tracked through operations like `Microsoft.Compute/virtualMachines/write`. - GCP: instance modification events include operations like `instances.setMetadata`, `instances.addResourcePolicies`, or `instances.resize`.
*Data Collection Measures:*
- AWS CloudTrail: Log Location: Stored in S3 or forwarded to CloudWatch. - Azure Activity Logs: Log Location: Accessible via Azure Monitor or exported to a storage account. - GCP Audit Logs: Log Location: Logs Explorer or BigQuery.

Executive priority
DC0073: Instance Modification is an official MITRE ATT&CK data component. Glexia treats it as defensive behavior context for prioritizing monitoring, control validation, and response planning without using the object by itself as an attribution claim.
Technical view
Security teams should validate DC0073: Instance Modification by reviewing the official ATT&CK relationships, mapped tactics (the mapped ATT&CK tactic context), supported platforms (the platforms named in the official object), and available local telemetry before making detection or mitigation decisions.
Likely telemetry
- Official ATT&CK relationships and object metadata
Detection direction
- Validate whether DC0073: Instance Modification appears in your detection coverage and tabletop scenarios.
- Use the object to align executive risk language with SOC, incident response, and detection engineering work.
- Do not treat ATT&CK relationship context as attribution without corroborating evidence.
Mitigation priorities
- Map the object to existing controls and identify missing telemetry or response ownership.
- Prioritize mitigations that reduce exposure on the listed platforms and tactics.
- Review adjacent ATT&CK relationships before changing policy, detections, or reporting language.
Additional notes and limits
Baseline Glexia take generated from the official MITRE ATT&CK STIX object, source hash, tactics, platforms, and detection fields. It is safe to replace with a richer model-generated take for the same source hash later.
This baseline take is source-grounded and schema-validated, but it does not include environment-specific telemetry, incident evidence, or threat-intelligence corroboration.

How security teams should use this page
Treat this object as behavior context, not an attribution claim. Validate the related groups, software, data sources, and mitigations against official ATT&CK relationships and your own telemetry before making control-coverage decisions.

Object version and sync metadata
The fields below describe the current mirrored snapshot. When Glexia retains multiple ATT&CK source imports, you can open the table to compare the same object across releases (hashes and MITRE timestamps). For MITRE’s own release notes and roadmap, see ATT&CK resources — Updates.
Imported snapshots across ATT&CK releases(3)
| Release | Bundle imported | Object version | Modified | Status | Raw hash |
|---|---|---|---|---|---|
| 20.0 | 2.1 | Older bundle | 5f5f9e6c6ce2… | ||
| 19.2 | 2.1 | Current bundle | 5f5f9e6c6ce2… | ||
| 19.1 | 2.1 | Older bundle | 5f5f9e6c6ce2… |
Mirrored ATT&CK source object
The raw object is retained through the mirrored ATT&CK source bundle and object hash. The raw endpoint returns the exact object from the mirrored bundle when available.
External references and citations
MITRE external references are preserved separately from Glexia analysis so citations remain traceable to their original source records.
