Workshop: Hands on Kerberos with Tim Medin

Workshop: Hands On Kerberos with Tim Medin Red Siege

Overview

  • Course Length: 4 hours
  • Support from expert instructors
  • Includes a certificate of completion
Instructor:

In this workshop, you’ll get an overview of Kerberos based on a section straight from Red Siege’s Offense for Defense (O4D) course and another excerpt from the new Pen Testing: Beyond the Basics class.

We’ll cover what Kerberos is, and how to attack it. You’d work through a hands on lab exercise involving Kerberoasting (Tim’s baby), the silver ticket attack, and the golden ticket attack.

Syllabus

  • Examine how Active Directory and Kerberos work to provide authentication and authorization

    • Kerberoasting
    • Silver Ticket Attack
    • Golden Ticket Attacks
    • Overpass-the-Hash

    • Kerberos Delegation Issues
