The sample is a Word document containing VBA macros, including AutoOpen and Auto_Close, which are commonly used to execute malicious code upon opening or closing the document. The document body presents a fake management agreement, acting as a lure to encourage macro execution. The presence of VBA macros strongly suggests an attempt to download and execute a secondary payload.
