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.
