T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a large number of external links, a technique often used for SEO manipulation or to distribute malicious content. The ML classifier strongly indicated maliciousness. The document body contains a URL that points to a Mossberg shotgun parts diagram, likely a lure to disguise the malicious intent. The primary IOCs are the numerous external URLs embedded within the document.

Heuristics 4
-
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.
-
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://cptsd-healing.net/uploads/1/3/0/8/130873795/130873795.html#mossberg+shotgun+parts+diagram PDF link annotation
