Dirk-jan is one of the core researchers of Active Directory and Azure AD at Fox-IT. Amongst the open source tools published to advance the state of AD research are aclpwn, krbrelayx, mitm6, ldapdomaindump and a Python port of BloodHound. He blogs at dirkjanm.io, where he publishes about new Active Directory attack chains, which included the discovery of the PrivExchange vulnerability. He is also co-author of ntlmrelayx and contributor to several other open source tools and libraries. After discovering that breaking stuff is a lot of fun he never looked back at his freelance web developer days, but is still thankful for the knowledge and experience that those days provided him.
