T1059.007 JavaScript
This PDF file was flagged by a machine learning classifier as malicious. It contains a large number of external links, characteristic of a link farm designed to host or redirect to malicious content. The PDF_SEO_LINK_FARM heuristic specifically indicates a mass of external PDF links, suggesting an attempt to distribute malware or conduct phishing operations. No scripts were extracted, but the embedded URLs are the primary indicators of malicious intent.

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://fun2gotravel.voyagerwebsites.com/uploads/1/3/0/7/130740205/130740205.html#%25D8%25B5%25D9%2588%25D8%25B1+%25D8%25AC%25D9%2586%25D8%25B3%25D9%258A%25D8%25A9+%25D9%2584%25D8%25B3%25D9%2581%25D8%25A7%25D8%25AD+%25D8%25A7%25D9%2584%25D9%2585%25D8%25AD%25D8%25A7%25D8%25B1%25D9%2585+%25D8%25A7%25D9%2584%25D8%25B4%25D8%25A7%25D8%25B0
