T1204.002 Malicious File
T1566.001 Spearphishing Attachment
T1059.005 Visual Basic
The file is an Excel 4.0 macro-enabled spreadsheet that uses an Auto_Open macro to execute. It impersonates DocuSign, a common lure to trick users into enabling macros. The extracted URLs are likely used to download a second-stage payload. The XLM macro itself is heavily truncated, preventing a more detailed analysis of its specific actions.
