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

The PDF file contains a large number of embedded external links, identified as a PDF_SEO_LINK_FARM heuristic. The document body also contains a call-to-action phrase, 'CLICK HERE TO GET YOUR MANUAL INSTANTLY', suggesting a lure to download content. ClamAV detection confirms this as Pdf.Phishing.TtraffRobotInstall. The primary intent appears to be directing users to download potentially malicious files from a network of linked domains.

Heuristics 4

  • 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.
