In this part we’re discussing the different types of windows hashes and focus on the NTLM authentication process.

We decided to look at the most popular on-premise helpdesk solutions. In this article we explain how we managed to find and exploit multiple vulnerabilities that eventually lead to remote code execution (RCE) at DeskPro software utilized by thousands of organizations using Bitdefender and Freelancer Inc in a case study. No full exploit is currently available, but steps can be easily reproduced and used to build one.

  Part of an upcoming series trying to shed the light on attacks targeting Microsoft Kerberos implementation in Active Directory …
