AN1616: Analytic 1616
Detection of identity directory enumeration through API calls or administrative queries retrieving multiple account objects within a short interval.
Analyst context for executives and security teams
This analytic matters because rapid retrieval of many identity directory account objects can be an early warning that someone is mapping the organization’s user base through the identity provider. For leaders, the value is not just detecting a query spike; it is validating whether the identity platform can show who queried directory data, how much was retrieved, and whether that activity was expected administrative work.
Executive priority
Prioritize this as an identity visibility and incident-readiness control. Directory enumeration can affect business resilience because identity data often guides later unauthorized access attempts, phishing preparation, or privilege targeting. Executives should ask whether identity-provider audit logs are retained, searchable, and mapped to accountable users or applications, and whether SOC teams have thresholds and escalation criteria for unusual bulk account lookups.
Technical view
The supplied ATT&CK object describes detection of identity directory enumeration through API calls or administrative queries that retrieve multiple account objects within a short interval on Identity Provider platforms. SOC and detection teams should validate whether identity-provider audit events capture directory read/query operations, request initiator, application/client identity, source context, query volume, result count, and timing. Because no official detection logic or tactic mapping is supplied, local baselining is required to distinguish legitimate administration, synchronization, reporting, or helpdesk activity from unusual enumeration patterns.
Likely telemetry
- Identity provider audit logs for API calls and administrative directory queries
- Events showing account object reads, searches, listings, or bulk retrievals
- Initiating user, service principal, application, or administrative account identity
- Timestamp, source network context, client/application identifier, and request metadata where available
- Result counts or indicators of multiple account objects returned within a short interval
Detection direction
- Confirm that identity-provider logging records both API-based and administrative-query-based directory access, not only authentication events.
- Build or validate baselines for normal bulk account retrieval by administrators, automation, reporting jobs, and synchronization services.
- Alert on short-interval retrieval of multiple account objects when the initiator, application, source, or volume is unusual for the environment.
- Tune carefully to reduce false positives from legitimate identity administration, provisioning, compliance reporting, and directory synchronization.
- Ensure investigations can pivot from the query event to the initiating identity, permissions used, application/client, source context, and subsequent identity activity.
Mitigation priorities
- Restrict directory read permissions to roles, users, and applications with a documented business need.
- Review administrative and application permissions that allow broad account-object retrieval in the identity provider.
- Maintain identity-provider audit log retention and SOC access sufficient to support investigation of enumeration patterns.
- Use least privilege and periodic access review for administrative accounts, service principals, and automation that can query directory data.
- Document approved bulk directory-query use cases so detection teams can tune known-good activity and escalate deviations.
Analyst notes and limits
This is a detection analytic object, not a technique description. The available ATT&CK content is limited to the analytic name, platform, and description. There are no supplied relationships, tactics, mitigations, or official detection logic. The strongest defensive use is as a validation prompt for identity-provider audit coverage and baselined detection of bulk account-object retrieval.
No official detection implementation, relationship context, tactic mapping, or vendor-specific event fields were supplied. Thresholds such as 'multiple account objects' and 'short interval' must be defined from local identity-provider behavior, business processes, and logging capabilities.
