The sample is an Excel 4.0 (XLM) macro sheet, which is a strong indicator of malicious intent. The document body contains text that impersonates a document signing service, likely to trick the user into enabling macros. The presence of multiple URLs suggests a downloader functionality, aiming to retrieve and execute a secondary payload. No scripts were extracted from this sample.
