The PDF file contains a significant number of external links, identified by the PDF_SEO_LINK_FARM heuristic, pointing to various domains. The document body text mentions 'Messenger apk para ios 7. 1. 2', suggesting a lure to trick users into visiting these malicious links. The primary attack pattern observed is a link farm used for phishing or distributing further malware. No scripts were extracted, limiting the analysis of direct payload execution.

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://jeansexpress.org/uploads/1/3/0/5/130542875/130542875.html#messenger+apk+para+ios+7.+1.+2 PDF link annotation
