A cross-platform assistant for creating malicious MS Office documents. Can hide VBA macros, stomp VBA code (via P-Code) and confuse macro analysis tools. Runs on Linux, OSX and Windows.
At the time of writing, this tool is capable of getting a default Cobalt Strike macro to bypass all major antivirus products and most maldoc analysis tools (by using VBA stomping in combination with random module names).
