Modernizing Offensive .NET Techniques for Red Teams

/ 1 min read

🧩 Modernizing Offensive .NET Tradecraft: Enhancing Red Team Techniques. Red teams are evolving their strategies for executing .NET assemblies in memory, focusing on custom command-and-control (C2) frameworks and advanced post-exploitation tools. This article discusses the use of Common Language Runtime (CLR) customizations to improve operational security and bypass the Anti-Malware Scan Interface (AMSI). Key techniques include managing memory allocations and implementing a custom assembly loading manager, which allows operators to load assemblies from memory without triggering AMSI scans. The author provides a proof-of-concept demonstrating these methods, emphasizing the importance of understanding CLR mechanics for effective defense strategies against post-exploitation tooling. The research highlights the ongoing cat-and-mouse game between offensive tactics and defensive measures in cybersecurity.
