T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF was flagged by an ML classifier as malicious and contains heuristics indicating it is a fake download lure. The document body and embedded URLs point to a domain designed to trick users into downloading further malicious content, likely a second-stage payload. The primary URLs associated with the fake download are http://uncpbisdegree.com/download3.php?q=solution-radiative-heat-transfer-modest.pdf and http://uncpbisdegree.com/download4.php?q=solution-radiative-heat-transfer-modest.pdf.

Fake 'free download' SEO-poisoning PDF critical PDF_SEO_FAKE_DOWNLOADThe 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.
