Description
The CA policy EditFlags was queried.
Attacker's Goals
- Querying this registry value can indicate an attacker is looking for an enabled EDITF_ATTRIBUTESUBJECTALTNAME2 flag.
- When this flag is enabled, it allows users to request certificates with a Subject Alternate Name(SAN).
- This can allow an attacker to obtain a certificate with higher privileges.
Investigative actions
- Check if the action was allowed by the user.
- Monitor certificate enrollments with Subject Alternate Names.
- Check for unusual high privilege users certificate authentications.
