MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of embedded links pointing to other PDF files across various domains. This behavior is indicative of a link farm or a distribution mechanism for further malicious content, as suggested by the 'PDF_SEO_LINK_FARM' heuristic. The ClamAV detection further supports its malicious nature. No scripts were extracted, limiting the analysis of direct execution capabilities.

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.
