MITRE ATT&CK
T1204.001 User Execution: Malicious Link T1566.002 Phishing: Spearphishing Link

The sample is a PDF containing a high volume of external links (31 total) to other PDFs hosted on disparate domains, triggering the PDF_SEO_LINK_FARM heuristic. The document body contains nonsensical text and binary data, which is typical of SEO spam designed to deceive search engines rather than human readers. ClamAV has flagged this as Pdf.Phishing.TtraffRobotInstall, indicating a known phishing pattern.

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.
