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

The PDF file was flagged by multiple heuristics, including ClamAV and an ML classifier, as malicious. The primary heuristic indicates a PDF SEO link farm, with 31 external PDF links generated. The document body contains garbled text but includes the URL http://tate.betterqualityreviews.com/uploads/2020/01/28/tipos-ruzelagesalajub-fevulapekonujom-pasixuboriza.pdf, which is also listed as the first URL in the link farm. This suggests the document's purpose is to redirect users to a network of malicious or SEO-abused PDF files.

  • 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.
