Description
This module provides a hands-on deep dive into the creation and delivery of malicious Microsoft Office documents using VBA macros, commonly leveraged as an initial access vector in red team operations and real-world cyberattacks. It begins by walking the reader through the lab setup using Windows 10 and Parrot OS, followed by the generation of reverse shell payloads using msfvenom, their encoding (e.g., XOR), and embedding them in Office macros via the VBA scripting language. Key API functions like VirtualAlloc, RtlMoveMemory, and CreateThread are explored to inject and execute payloads directly in memory, with advanced evasion strategies such as sandbox detection, AMSI bypass, and delayed execution.
The guide also addresses stealth and delivery tactics, from phishing scenarios and macro obfuscation to bypassing Protected View and Microsoft Defender. To support both red and blue teams, the module concludes with detection tips for defenders, emphasizing behavioral signals like Office spawning LOLBins and memory injection patterns. Overall, this training offers a full-cycle offensive methodology while stressing the importance of ethical boundaries, testing only in authorized or lab environments.
