<p>Forged web credentials in Office Suite contexts may appear as abnormal authentication headers in Outlook or Teams traffic, or unexplained OAuth grants in M365/Azure logs. Defenders should correlate token usage events with missing authentication flows and mismatched device/user context.</p>

Log sources and channels
Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.
| Log source | Channel | Data component |
|---|---|---|
| m365:oauth | OAuth grants or tokens issued without expected user consent | DC0006 Web Credential Creation |
| m365:signinlogs | Token usage events with device/user mismatch | DC0067 Logon Session Creation |
Mutable elements
Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.
| Field | Description |
|---|---|
OAuthAppAllowlist | Approved OAuth apps and flows; flag unapproved or unexpected token grants. |
