MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF contains a large number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic, which is a common technique for distributing malicious content or conducting phishing attacks. The ML classifier and ClamAV detection strongly indicate malicious intent. The document body is heavily obfuscated and does not provide clear user-facing content, but the presence of numerous external links points to a redirection-based attack. No scripts were extracted from this sample.
