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

The PDF file contains a large number of embedded URLs pointing to other PDF files, indicating a link farm or redirection scheme. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the 'PDF_SEO_LINK_FARM' heuristic strongly suggest a phishing or SEO abuse campaign. The embedded URLs are likely used to distribute malicious content or manipulate search engine results.

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.
