Over on our Vimeo, Fortalice Director of Offensive Cybersecurity Operations (OCO) Matt Shirley talks the red team's perspective on cyber threats and exploiting them on behalf of our clients.
Take a look:
Active Directory Certificates and PKINIT are hot topics these days and our operators at Fortalice have been doing their best to stay on top of the new research and tools. My previous blog touched on PyWhisker and referenced one of its resources available on https://thehacker.recipes. While reading through the documentation there, a note near the bottom caught my eye, which stated: User objects can't edit their own msDS-KeyCredentialLink attribute while computer objects can.
On a recent red team engagement, our team was tasked with focusing on Active Directory Certificate Services (ADCS) exploitation. The objective was to identify certificate template misconfigurations and potentially achieve privilege escalation by abusing them. The concepts and attacks used were based around the work and whitepaper by Will Shroeder (@harmj0y) and Lee Christensen (@tifkin_).
