M365 SharePoint/OneDrive File Access via PowerShell source high: Identifies file downloads or access from OneDrive or SharePoint using PowerShell-based user agents. Adversaries may use native PowerShell cmdlets like Invoke-WebRequest or Invoke-RestMethod with Microsoft Graph API to exfiltrate data after compromising OAuth tokens via device code phishing or other credential theft techniques. This rule detects both direct PowerShell access and PnP PowerShell module usage for file operations. FileAccessed events are included to detect adversaries reading file content via API and saving locally, bypassing traditional download methods. Normal users access SharePoint/OneDrive via browsers or sync clients, making PowerShell-based file access inherently suspicious.T1059, T1059.001, T1213, T1213.002, T1530↳ also matches FileDownloaded

O365 OneDrive Anonymous File Accessed source medium: Anonymous links can be used to export files from OneDrive.

M365 SharePoint Search for Sensitive Content source low: Identifies search queries in SharePoint containing sensitive terms related to credentials, financial data, PII, legal matters, or infrastructure information. Adversaries who compromise user accounts often search for high-value files before exfiltration. This rule detects searches containing terms across multiple sensitivity categories, regardless of the access method (browser, PowerShell, or API). The actual search query text is analyzed against a curated list of sensitive terms to identify potential reconnaissance activity.T1213, T1213.002, T1530, T1619

M365 audit records use different field names on each surface #

The same Unified Audit Log record uses different field names on each surface. A query built for one surface can silently miss on another. These pages document the Management Activity API JSON names, the same names Search-UnifiedAuditLog and the Office 365 Management Activity API return.

Purview CSV export flattens each record to four columns (CreationDate, UserIds, Operations, AuditData). The API field names live only inside the AuditData JSON blob. Expand it with ConvertFrom-Json. The wrapper columns are renamed too: CreationDate not CreationTime, UserIds not UserId, Operations not Operation.
Sentinel's OfficeActivity table renames several fields and turns two integer enum columns into strings. The table below maps them.

API JSON (event pages)	OfficeActivity column	Note
`Id`	`OfficeId`	Renamed.
`Workload`	`OfficeWorkload`	Renamed.
`ObjectId`	`OfficeObjectId`	Renamed.
`CreationTime`	`TimeGenerated`	Renamed. OfficeActivity has no `CreationTime` column.
`SiteUrl`	`Site_Url`	Renamed (SharePoint family).
`RecordType`	`RecordType`	Same name; the Int32 enum becomes its string enum name.
`UserType`	`UserType`	Same name; the Int32 enum becomes a string.
`ClientIP`	`ClientIP`, `Client_IPAddress`	Both columns present on OfficeActivity.
`Scope`	(none)	No OfficeActivity equivalent under any name. Recover it from the API JSON or the Purview `AuditData` blob.
`Operation`, `UserId`, `ResultStatus`, `UserKey`, `AppAccessContext`, `OrganizationId`	same names	Unchanged. No `_s` / `_d` suffixes (a native table, not a custom log).

Mapping verified against the OfficeActivity table reference, the Management Activity API schema, and the Purview audit-record export format.
