T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a large number of embedded external links, a technique often used for SEO spam or to redirect users to malicious sites. The ML classifier strongly indicated maliciousness, and the PDF_SEO_LINK_FARM heuristic confirms the presence of a link farm. While no scripts were explicitly extracted, the embedded URLs are the primary indicators of malicious intent, likely serving as a distribution point for further malware or phishing content.

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://3kg.undesirable.us/uploads/1/3/0/8/130874593/130874593.html#%25D9%2582%25D8%25B5%25D8%25B5+%25D8%25AC%25D9%2586%25D8%25B3+%25D8%25AC%25D9%2585%25D8%25A7%25D8%25B9%25D9%258A%25D8%25A9+%25D9%2586%25D8%25A7%25D8%25B6%25D8%25AC%25D8%25A9
