T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV and an ML classifier, with heuristics indicating the presence of external URIs. While the document body is heavily obfuscated, the embedded URLs and the PDF structure suggest a phishing attempt. No scripts were extracted, limiting the ability to determine specific malicious actions beyond leading the user to external content.
