### Description
ADFS DKM key attribute (thumbnailphoto) access in AD container, potential Golden SAML token forging attempt.
### Attacker's Goals
The attack goal is to forge a valid SAML token to impersonate any user and gain persistent, unauthorized access to cloud resources, effectively bypassing MFA and standard security controls.
### Investigative actions
* Check for recent changes to the SAML signing certificate on both the Identity Provider and the Service Provider to rule out a configuration drift or expiration issue.
* Check for other correlated alerts on on-premises systems that may be related to the Golden SAML attack.
* Look for signs that the user account is compromised (e.g. abnormal logins, unusual activity).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://cortex-docs.paloaltonetworks.com/analytics-alerts/alerts-by-name/adfs-dkm-key-access.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
