Detects Corporate Breaches
Before Attackers Do

The first proactive solution that provides instant pain relief for Active Directory infrastructures - the common denominator of targeted cyber attacks.

Active Directory: The Main Target of Every Attack

In any organisation, Active Directory is the system that supports and provides access to all vital information and assets. Because this system is in constant mutation, breaches are unknowingly opened on a regular basis, making it the most vulnerable part of an organization's IT security. As a matter of fact, every modern cyber attack exploits Active Directory.

SingHealth hack#2: a more in-depth dive

In a previous post, we have tried to tell, in layman’s words, the tale of the now-infamous SingHealth hack. Today we take this discussion a step further.  A deep read through the 453-page report released by the Committee of Inquiry (COI) on January 10th allows for a safe assumption: the attack indeed reached a turning point when it succeeded compromising SingHealth’s Active Directory (AD). But what exactly went wrong with this critical infrastructure?

Abusing S4U2Self: Another Sneaky Active Directory Persistence

As part of the recent publication of Elad Shamir’s work on Kerberos delegation (“Wagging the Dog - Abusing Resource-Based Constrained Delegation to Attack Active Directory”), Alsid is publishing a series of blogposts deepening the uncovered new attack vectors and shedding a light on pragmatic solution for Blue Teams trying to measure the impact of this breakthrough on their Active Directory infrastructure. This second publication will be focused on Kerberos’ S4U2Self extension. In his paper Shamir describes a new Active Directory backdoor based on this unsung functionality. This blogpost will examine how this technique can be extended to target different types of AD accounts after describing how an attacker would deploy and use such a backdoor. Using the opposite delegation direction, we will then describe another possible loophole. We will end with specific details and considerations to help security teams protecting themselves against those scenario.

Kerberos Resource-Based Constrained Delegation: a new control path

This article is part of a series that explore new ways to compromise an Active Directory. The series follows an outstanding paper published by Elad Shamir: “Wagging the Dog - Abusing Resource-Based Constrained Delegation to Attack Active Directory”. The first article will focus on an AD objects ownership and permissions, the next one will address the backdoor aspect of the new-found persistence technique.
