⚔️ Maelstrom: C2 Development Blog Series

We wanted to explore how C2s function in 2022, what evasive behavior's are required, and what a minimum viable C2 looks like in a world of sophisticated endpoint protection.

Which gave us our goals for this blog series:

- Document the internals of a minimum viable C2:
* What are the ideas behind popular C2 implementations?
* What are their goals and objectives?
- Analyse and implement evasive behaviors:
* What is required to run on a contemporary Windows system?
* What is required to bypass up-to-date, modern endpoint protection?
- Produce a proof-of-concept C2:
* What is the minimum viable C2 for an operator in 2022?
* What is required to detect this minimum viable C2?

🐞 Malware Development for Dummies

In the age of EDR, red team operators cannot get away with using pre-compiled payloads anymore. As such, malware development is becoming a vital skill for any operator. Getting started with maldev may seem daunting, but is actually very easy. This workshop will show you all you need to get started!

🔴 Reversing BRc4 Red-Teaming Tool Used by APT 29

On May 19, a malicious payload associated with Brute Ratel C4 (BRc4) was uploaded to VirusTotal, where it received a benign verdict from all 56 vendors that evaluated it. Beyond the obvious detection concerns, we believe this sample is also significant in terms of its malicious payload, command and control (C2), and packaging.

👨‍👩‍👦 Book Can Save A Life

I will be very happy if this book helps at least one person to gain knowledge and learn the science of cybersecurity. The book is mostly practice oriented. This book is dedicated to my wife, Laura, and my children, Yerzhan and Munira. Also, thanks to everyone who is helping me through these difficult times. The proceeds from the sale of this book will be used to treat Munira, who is currently battling for her life at a hospital in Istanbul, Turkey.

The book is divided into three logical chapters:

— Malware development tricks and techniques;
— AV evasion tricks;
— Persistence techniques.

This book costs $16 but you can pay as much as you want. All money will go to the treatment of her daughter.

Dear cocomelonc (@abuyerzh) I wish you and your daughter health and well-being!

🐚 PSAsyncShell: Asynchronous Firewall Bypass

PSAsyncShell is an Asynchronous TCP Reverse Shell written in pure PowerShell.

Unlike other reverse shells, all the communication and execution flow is done asynchronously, allowing to bypass some firewalls and some countermeasures against this kind of remote connections.
