mean there aren’t excellent resources out there to help you along the way!

In our first instalment of this

blog

series, we covered some of the most common vulnerabilities and techniques threat hunters should be familiar with, and more importantly how you can hunt for them in your organizations. This time around, we are covering more sophisticated techniques that adversaries, from basic cyber criminals to advanced threat actors, use. Sit down, buckle up, and get ready for 3 MORE videos that will make you an even better threat hunter!

While the Windows operating system, offers legitimate users several ways to download files, for an adversary it isn’t always so easy. This is because in the early stages of a compromise, the actor may only be limited to a basic shell offering simple tools. However, those malicious actors have developed a number of methods of “ingressing” tools into an environment and threat hunters need to know what to look for to identify suspicious download activity.

Actors of all skill levels are known to actively target RDP for a variety of reasons. It is therefore imperative that threat hunters are familiar with its normal (and abnormal) behaviors in an environment. In this video we dive into how actors can hijack inactive RDP sessions using the Living off the Land (LotL) binary Tscon.exe
