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

The PDF file contains a large number of embedded URLs pointing to other PDF files hosted on various domains. This behavior is indicative of a link farm or SEO manipulation tactic, as flagged by the PDF_SEO_LINK_FARM heuristic. The ClamAV detection further supports its malicious classification. The document body's content is largely unreadable due to encoding issues, but the presence of numerous external links is the primary indicator of malicious intent.

Heuristics 3

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
