T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a large number of external links, many pointing to PDF files hosted on various platforms, suggesting a link farm or redirection mechanism. The primary URL, 'https://jacksth.ru/wix?keyword=distributive+property+and+combining+like+terms+worksheet+kuta', appears to be a lure designed to attract users searching for educational materials. While no scripts were explicitly extracted, the heuristic 'PDF_SEO_LINK_FARM' and the sheer volume of external URLs indicate a malicious intent to drive traffic to potentially harmful sites, likely for phishing or malware distribution.

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 https://jacksth.ru/wix?keyword=distributive+property+and+combining+like+terms+worksheet+kuta PDF link annotation
