Cobalt Strike, a Defender’s Guide

In this research, exposes adversarial Tactics, Techniques and Procedures (TTPs) as well as the tools use to execute mission objectives. In most of cases, the threat actors utilizing Cobalt Strike. Therefore, defenders should know how to detect Cobalt Strike in various stages of its execution. The primary purpose of this articles is to expose the most common techniques from the intrusions track and provide detections. Having said that, not all of Cobalt Strike’s features will be discussed.

ntTraceControl — Powershell Event Tracing Toolbox

Want to simulate any ETW logs using powershell, even the security one?
Do you want to import any evtx files into the current eventlog session?

ntTraceControl is a set of Powershell commands to forge/generate Windows logs. Simply put, ntTraceControl supports Detection teams by simplifying the testing of detection use cases and alerts without using complex infrastructure, tools, or the testing of vulnerabilities.

⏱ Scheduled Task Tampering

In this post we will explore two approaches that can be used to achieve the same result: create or modify a scheduled task and execute it, without generating the relevant telemetry. First, we will explore how direct registry manipulation could be used to create or modify tasks and how this did not generate the usual entries in the eventlog. Finally, an alternative route based on tampering with the Task Scheduler ETW will be presented that will completely suppress most of logging related to the Task Scheduler.

⚙️ WTFBins

WTFBin(n): a binary that behaves exactly like malware, except, somehow, it's not?
Site detailing noisy, false positive binaries created that's super helpful in getting filter ideas together for monitoring and hunting rules.

📒Simulating attacks with Sysmon

SysmonSimulator is an Open source Windows event simulation utility created in C language, that can be used to simulate most of the attacks using WINAPIs. This can be used by Blue teams for testing the EDR detections and correlation rules. I have created it to generate attack data for the relevant Sysmon Event IDs.

Attack coverage:

— Process Events
— File Events
— Named Pipes Events
— Registry Actions
— Image Loading
— Network Connections
— Create Remote Thread
— Raw Access Read
— DNS Query
— WMI Events
— Clipboard Capture
— Process Image Tampering

🛡 On Detection: Tactical to Functional

The goal of this series is to facilitate a conversation about the more technical aspects of attacks and how a deeper understanding at the more foundational levels helps to provide a batter base to build assumptions from.

🦮 BlueHound

It is an open-source tool that helps blue teams pinpoint the security issues that actually matter. By combining information about user permissions, network access and unpatched vulnerabilities, BlueHound reveals the paths attackers would take if they were inside your network
It is a fork of NeoDash, reimagined, to make it suitable for defensive security purposes.
