MITRE ATT&CK
T1566.001 Spearphishing Attachment

The sample is identified as a malicious Excel downloader by ClamAV. It contains an external hyperlink disguised as an invoice, which is a common lure for spearphishing attachments. The heuristic 'SE_INVOICE_LURE' further supports this, indicating the document's content is designed to trick users into clicking the link. No scripts were extracted, but the presence of external relationships and hyperlinks suggests the document is designed to download and execute a secondary payload.
