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

The PDF file contains a large number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic. The ClamAV detection indicates this is a known phishing or malicious redirection pattern. The embedded URLs likely lead to further malicious content or phishing sites, serving as a link farm to distribute traffic or host payloads.

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.
