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

The PDF document contains a high number of external links, many of which point to other PDF files hosted on similar domains. This pattern is indicative of a link farm or SEO spam tactic, often used to distribute malicious content or drive traffic. The heuristic 'SE_PAYMENT_REDIRECT_LURE' suggests a potential phishing attempt related to financial information. No scripts were extracted from this sample.

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.
  • Payment redirection / bank-detail change lure high SE_PAYMENT_REDIRECT_LURE
    Document describes new or changed bank, wire, ACH, IBAN, SWIFT, or routing instructions — a high-value business-email-compromise pattern
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
