T1059.007 JavaScript
The PDF file contains a large number of external links, identified by the 'PDF_SEO_LINK_FARM' heuristic, suggesting a link farm designed to redirect users to potentially malicious content. While no scripts were directly extracted, the presence of numerous external URIs, including one with a suspicious URL fragment, indicates an attempt to lure users to external sites. This is consistent with a phishing or malware distribution campaign.

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://un-mariage-a-la-reunion.fr/uploads/1/3/1/8/131857419/131857419.html#%25D9%2585%25D8%25A7+%25D9%2587%25D9%258A+%25D8%25A3%25D9%2582%25D8%25B1%25D8%25A7%25D8%25B5+%25D9%2581%25D9%258A%25D9%2586%25D8%25A7%25D8%25B3%25D8%25AA%25D9%258A%25D8%25B1%25D8%25A7%25D9%258A%25D8%25AF+%25D8%25A7%25D9%2584%25D9%2585%25D8%25B3%25D8%25AA%25D8%25AE%25D8%25AF%25D9%2585%25D8%25A9+%25D9%2584
