T1566.001 Spearphishing Attachment
T1059.007 JavaScript
This PDF document contains numerous external links, disguised as practice problems, which is a common lure for phishing or malware distribution. The ML classifier strongly indicated maliciousness, and the PDF structure suggests a link farm designed to redirect users to potentially harmful sites. No scripts were extracted, but the extensive use of external URLs points to a likely download or redirection attack.

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://xocobean.com/uploads/1/3/0/7/130740489/130740489.html#practice+algebra+2+problems+with+answers
