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

The PDF file contains a large number of embedded external links, as detected by the PDF_SEO_LINK_FARM heuristic. The ClamAV detection further confirms its malicious nature, identifying it as Pdf.Phishing.TtraffRobotInstall. The embedded URLs are likely used to redirect users to malicious sites or to manipulate search engine results. The document body contains fragmented text related to roofing contractors, which appears to be a lure.

  • 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.
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
