Kerberos offers plenty of user authentication features. Its main ‘bricks’ are tickets; in the course of penetration testing, the attacker dumps such tickets from the LSASS process memory at least once. Today, I will explain how this operation can be performed without sophisticated hacker tools.

To implement a number of pass-the-ticket attacks, you have to inject a Kerberos ticket into the compromised system. Such tools as Mimikatz, Impacket, or Rubeus can be used for this purpose, but they are easily detected by antiviruses, thus, making this approach ineffective. In this article, I will explain how the ticket injection problem can be solved without special tools: all you need is WinAPI and some magic.

In Windows, privileges play a key role: only the admin has the authority to grant special rights to users so that they can perform their tasks. This article discusses a software tool called Privileger: it enables you to search the system for accounts with certain privileges and change privileges assigned to a given account.

In Windows, most security mechanisms are based on user account passwords. Today, you will learn several techniques making it possible to intercept a password at the time of user authentication and write code that automates this process.
