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

The PDF document is identified as a fake download lure, using SEO poisoning techniques to trick users into clicking malicious links. The embedded URLs and document body content point to a deceptive download gateway. The primary malicious URLs are http://uncpbisdegree.com/download3.php?q=walking-in-the-dust-of-rabbi-jesus-how-jewish-words-can-change-your-life-lois-tverberg.pdf and http://uncpbisdegree.com/download4.php?q=walking-in-the-dust-of-rabbi-jesus-how-jewish-words-can-change-your-life-lois-tverberg.pdf, which are designed to deliver a payload.

Heuristics 4

  • Fake 'free download' SEO-poisoning PDF critical PDF_SEO_FAKE_DOWNLOAD
    The ML classifier flagged this PDF AND it carries a visual download/call-to-action lure AND an off-domain server-side download-gateway link whose query string names a document payload. This three-signal conjunction is the fake-document / 'free PDF download' SEO-poisoning delivery pattern: the page is padded with benign decoy links to dilute classifier scores while funnelling the victim through the gateway to malware/scareware. Acting only on the conjunction keeps benign download-bearing PDFs from being misflagged.
  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
