The GoSecure Titan Labs team saw an opportunity to further explore the topic of hash capturing (which is a must in the arsenal of any offensive team). This blog will examine RDP security modes, how they work and how to put that into action to capture NetNTLMv2 hashes via the RDP protocol using PyRDP—a library created by GoSecure.
