Abusing Unsafe Defaults in Active Directory Domain Services: A Real-World Case Study

This past July, Kevin Robertson from NetSPI released a blog post entitled, “Beyond LLMNR/NBNS Spoofing – Exploiting Active Directory-Integrated DNS,” which introduced a new technique (to us at least) targeting weak default access control in Active Directory Domain Services. At GoSecure, since most of our engagements require some level of Active Directory security assessment, we followed our interest and decided to find a way to reliably exploit it.

As part of our four-month internship at GoSecure, we chose to work on creating a Remote Desktop Protocol (RDP) honeypot. To achieve this, we used a Linux server with an RDP man-in-the-middle (MITM) program that redirects traffic to a real Windows Server.

Large Scale Vulnerability Scanning with Jenkins

Find Security Bugs can often uncover interesting findings that may lead to the discovery of critical vulnerabilities. Back in May, we published on this blog two vulnerabilities in components of Spring, a Java web framework, using this tool. However, the process of using Find Security Bugs can be a little bit tedious to unseasoned Java users. Also, the process of analyzing compiled code and triaging the findings needed improvements. Here is the solution that was built to find vulnerabilities at scale.
