Active Directory: DACL Abuse

Today, we'll explore the exploitation of insecure ACEs within the DACL of users and groups in an Active Directory environment.

Active Directory: Windows ACLs

Today, we’ll explore the fundamentals of ACLs in Windows and later demonstrate common attacks that exploit ACL misconfigurations in an Active Directory environment.

Active Directory: Attacking Kerberos

Today, we'll explore the exploitation of an AD environment, demonstrating how to carry out these attacks and apply the Kerberos Authentication Protocol in real-world exploitation scenarios.

Active Directory: Understanding Kerberos Authentication Protocol

In this article, we will dive into the theoretical foundations of Kerberos, explaining its core components, how the authentication process works.

Understanding the Heap: A Foundation for Advanced Exploitation

In this article, we explore the fundamentals of the heap as a stepping stone to understanding advanced memory corruption exploitation techniques.

Buffer Overflow - Ret2libc (Part 2)

Today, we will continue exploring the Ret2libc technique, with a focus on 64-bit exploitation.

64-bit vs 32-bit

Up to this point, we have covered exploiting binary vulnerabilities in 32-bit programs. However, with the prevalence of 64-bit computing systems today, this article will introduce x64 binary exploitation.

Format String Vulnerability
