New Vulnerability Found Using Techniques Taught at Black Hat USA
One of the topics I teach in Coalfire's Adaptive Penetration Testing course, given most recently at Black Hat 2017, is manual privilege escalation on Linux- and Unix-based systems. I also talk about how common it is to gain an initial foothold in an environment by leveraging default or easily guessable login credentials. During a recent red team engagement, I leveraged both of these techniques – not only to fully compromise the organization's Active Directory environment, but also to discover and exploit a previously unknown vulnerability in the Replibit Linux distribution installed on a server on their network.
