RFC 3514 proposes an IPv4 flag to allow traffic to flag itself as malicious or not. This RFC’s authors reason that if malicious programs opt into this standard, it will become easier for IDS and other security products to distinguish between packets with good and evil intent. Naturally, this RFC was written in jest. If […]

Named Pipe Pivoting
One of my favorite features in Cobalt Strike is its ability to pivot over named pipes. A named pipe is a way for two programs on a Windows system to communicate with each other. From a programming perspective, working with a named pipe is a lot like working with a file. I use named pipes […]
Advanced Threat Tactics – Course and Notes
The release of Cobalt Strike 3.0 also saw the release of Advanced Threat Tactics, a nine-part course on red team operations and adversary simulations. This course is nearly six hours of material with an emphasis on process, concepts, and tradecraft. If you’d like to jump into the course, it’s on YouTube: Here are a few […]
Cobalt Strike 3.0 – Advanced Threat Tactics
Cobalt Strike’s mission is to help security professionals emulate “advanced threat tactics” during their engagements. I’ve executed on this since the product’s 2012 release.

Aggressor is a ground-up rewrite of Cobalt Strike’s team server and client to better serve its Red Team Operations and Adversary Simulation use cases. I expect to ship this work […]
Raphael’s Magic Quadrant
BlackHat is about to start in a few days. I think this is an appropriate time to share a non-technical, business only post. There is a new market for offensive tools and services. Our trade press doesn’t write about it yet. I don’t believe industry analysts have caught onto these ideas yet. The leaders behind mature […]
Cobalt Strike 2.5 – Advanced Pivoting
I spend a lot of my red time in the Access Manager role. This is the person on a red team who manages callbacks for the red cell. Sometimes, I like to grab a Beacon and drive around a network. It’s important to get out once in a while and enjoy what’s there. Cobalt Strike […]
WinRM is my Remote Access Tool
One of my favorite blog posts last year was Adversary Tricks and Treats from CrowdStrike. In this post, CrowdStrike details the tradecraft of an actor they dub Deep Panda. In an attempt to skirt advanced malware hunting capability, Deep Panda leverages native tools to control target systems and spread laterally in a network. With the […]
Models for Red Team Operations
Recently, I had an email from someone asking for a call to discuss different models of red team operations. This gentlemen sees his team as a service provider to his parent organization. He wants to make sure his organization sees his team as more than just dangerous folks with the latest tools doing stuff no […]
