VBA Macros

olevba - a tool to extract VBA Macro source code from MS Office documents (OLE and OpenXML)

olevba is a script to parse OLE and OpenXML files such as MS Office documents (e.g. Word, Excel), to detect VBA Macros, extract their source code in clear text, decode malware obfuscation (Hex/Base64/StrReverse/Dridex) and detect security-related patterns such as auto-executable macros, suspicious VBA keywords used by malware, and potential IOCs (IP addresses, URLs, executable filenames, etc). It is part of the python-oletools package.
