MITRE ATT&CK
T1566.001 Spearphishing Attachment T1566.002 Spearphishing Link

The PDF file contains a large number of embedded links to external PDF documents, as indicated by the PDF_SEO_LINK_FARM heuristic. The ClamAV detection also flags this as a phishing-related threat. The embedded URLs are likely used to distribute malicious content or perform SEO abuse. No scripts were extracted from this sample.

Heuristics 3
