EvilClippy

EvilClippy is a cross-platform tool designed to create malicious Microsoft Office documents for security testing purposes. The tool provides capabilities to hide VBA macros within Office documents, making them less detectable by standard security analysis tools. It can perform VBA code stomping through P-Code manipulation, which replaces the readable VBA source code with compiled bytecode while maintaining functionality. EvilClippy is specifically designed to confuse and evade macro analysis tools that organizations use to detect malicious Office documents. The tool supports multiple operating systems including Linux, OSX, and Windows, providing flexibility for different testing environments. The primary use case for EvilClippy is in penetration testing and red team operations where security professionals need to create realistic phishing attack scenarios. It enables testers to evaluate an organization's defensive capabilities against sophisticated Office-based threats. The tool focuses on Microsoft Office document manipulation and provides various evasion techniques that mirror real-world attack methods used by malicious actors.
