T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a link farm designed to appear as a "12 week year study guide download" to entice users. The PDF_SEO_LINK_FARM heuristic indicates a mass of external links, likely to host further malicious content or phishing pages. No scripts were extracted from this sample, limiting the ability to determine specific payload delivery mechanisms beyond the embedded URLs.

Heuristics 5
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall 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.
-
Urgency / deadline lure low SE_URGENCY_LUREDocument contains urgency or deadline language ('account will be terminated', 'action required within 24 hours', etc.) — useful context, but low-signal without other findings
-
External URI info PDF_URIPDF contains an external URL action
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
-
Embedded URL info EMBEDDED_URLOne 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.URL http://scheercoaching.com/uploads/1/3/0/8/130813428/130813428.html#12+week+year+study+guide+download PDF link annotation
