Running Once, Running Twice, Pwned! Windows Registry Run Keys

The Windows registry is a vast and complex topic and cannot be understood and defended in one article. One particular area of interest from a security perspective is registry run keys. In this article, we discuss who uses them, how to uncover abuse, and how to eradicate evil from them.

Pwning Windows Event Logging with YARA rules

The Event Log coupled with Windows Event Forwarding and Sysmon can be extremely powerful in the hands of defenders, allowing them to detect attackers every step of the way. Obviously this is an issue for the attackers. Before privilege escalation it is limited what we can do to evade event logging, but once privileges have been elevated it is an equal playing field. In the past I have released a...

Defending Your Malware

Malware is an important part of an engagement, though as many security solutions are now evolving past rudimentary signature comparisons to using more advanced techniques to detect malicious activity, it is important that we as attackers understand the methods they are using and how we can avoid them. Consider the following code I wrote for example. #include <stdio.h> #include...

shad0w

Post exploitation is large part of a red team engagement. While many organisations begin to mature and start to deploy a range of sophisticated Endpoint Detection & Response solutions (EDR) onto their networks, it requires us, as attackers to also mature. We need to upgrade our arsenal to give us the capabilities to successfully operate on their networks. That is why today, I am releasing shad0w.

shad0w is a post exploitation framework which is designed to operate covertly on such networks, providing the operator with much greater control over their engagements. Over future blog posts I will go into greater detail on the intricacies of how shad0w works. This blog post will, therefore, serve as an introduction into the usage and features that shad0w has to offer.

Bypassing Antivirus with Golang – Gopher it!

In this blog post, we’re going to detail a cool little trick we came across on how to bypass most antivirus products to get a Metepreter reverse shell on a target host. This all started when we came across a Github repository written in Golang, which on execution could inject shellcode into running processes. By simply generating a payload with msfvenom we tested it and found that it was easily...
