Description
A process queried the ADFS database decryption key (DKM key) via LDAP.
Attacker's Goals
- An attacker wanting to perform a golden SAML attack will want to steal the ADFS token-signing certificates.
- To steal the token-signing certificates, the attacker will need to access the ADFS database
- To access the encrypted ADFS database, an attacker will attempt to retrieve the decryption key via an LDAP query.
Investigative actions
- Check if the LDAP search query was allowed for the user (logged on at event time) or process.
- Check for unusual ADFS logins.
- Check the process that initiated the query.
- Investigate the LDAP search query for any suspicious indicators.
Variations
LDAP query explicitly queried the ADFS database decryption key (DKM key)
