What is it?

Authentication is the process by which a system confirms the identity of a user or application. It's essentially all about who you are.

Targeting authentication mechanisms allow us to to impersonate users, admins, or systems and gain unauthorized access. Often, we look to attack logic issues and lack of brute-force protection.

Common targets in authentication attacks include:

  • Passwords or passphrases

  • Multi-Factor Authentication (MFA)

  • Session tokens

  • Cookies

  • Recovery questions and answers

For more details on specific authentication attack techniques, see the relevant child pages.
