Description

Certutil was used to parse a pfx certificate file.

Attacker's Goals

Attackers want to check pfx details. If details suffice, the correct certificate can be used for authentication, persistence or NTLM extraction.

Investigative actions

  • Check if the pfx parsing is legitimate for the user (Testing, IT, etc.).
  • Follow further actions done by the user (ex. authentication using certificates).
