This is the third in a three-part series of blog posts discussing how to abuse Kerberos delegation! If you haven't already, feel free to read the first blog post, as they discuss the Kerberos authentication process and how delegation plays an important role in solving the double-hop problem, and how to abuse unconstrained delegation.

This article was written to provide readers with an overview of a selection of our pentest results from the last 15 months. This data was gathered toward the end of September 2025. Shockingly, the data does not differ much from our prior analyses conducted at the end of 2022 or 2023.

In Active Directory exploitation, Kerberos delegation is easily among my top favorite vectors of abuse, and in the years I’ve been learning Kerberos exploitation, I’ve noticed that Impacket doesn’t get nearly as much coverage as tools like Rubeus or Mimikatz.

Imagine this: You’re an attacker ready to get their hands on valuable data that you can sell to afford going on a sweet vacation. You do your research, your recon, everything, ensuring that there’s no way this can go wrong. The day of the attack, you brew some coffee, crack your knuckles, and get started. A few hours into the service scan, you come to realize that all the network ports are open, but in use.

Many web application firewalls (WAFs) can be bypassed by simply sending large amounts of extra data in the request body along with your payload. Most WAFs will only process requests up to a certain size limit. How the WAF is configured to handle these large requests determines exploitability, but some common WAFs will allow it by default.

The Microsoft Store provides a convenient mechanism to install software without needing administrator permissions. The feature is convenient for non-corporate and home users but is unlikely to be acceptable in corporate environments. This is because attackers and malicious employees can use the Microsoft Store to install software that might violate organizational policy.

Whether it's forgotten temporary files, installation artifacts, READMEs, or even simple image files--default content on web servers can turn into a boon for attackers. In the most innocent of cases, these types of content can let attackers know more about the tech stack of the environment, and in the worst case scenario can lead to exploitation.
