T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic. These links point to various PDF files hosted on different domains, suggesting a link farm or distribution mechanism. The ML classifier also strongly indicated maliciousness. No scripts were extracted, and the document body was unreadable, but the extensive link farm points to a malicious intent, likely to manipulate search engine results or distribute further malware.

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://infiniment.net/uploads/1/3/1/4/131452954/131452954.html#%25D8%25B5%25D9%2588%25D8%25B1+%2528%25D8%25B3%25D8%25AA%25D9%2588%25D8%25B1%25D9%2585%25D9%258A+%25D8%25AF%25D8%25A7%25D9%2586%25D9%258A%25D9%2584%25D8%25B2%2529+%25D8%25A7%25D9%2584%25D8%25AC%25D9%2586%25D8%25B3%25D9%258A%25D8%25A9
