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

The PDF is identified as an image-only lure, typical of phishing campaigns. It contains a large number of embedded URLs pointing to other PDF files, suggesting a link farm or a method to distribute malicious content under the guise of legitimate documents. The primary URL, http://fireflytrail.org/uploads/1/3/0/4/130488810/130488810.html#c+the+complete+reference, is likely the initial point of interaction for the user.

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.
  • Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE
    PDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 25 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • 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.
