T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains numerous external links, identified as a link farm, and is flagged by ClamAV as a phishing trojan. The primary URL, 'https://ponafet.ru/strik?utm_term=14.3+mechanical+advantage+and+efficiency+worksheet+answers', suggests a lure related to academic content to entice users to click. While no scripts were explicitly extracted, the PDF structure and link farm indicate malicious intent, likely to redirect users to a phishing site or download further malware.

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://ponafet.ru/strik?utm_term=14.3+mechanical+advantage+and+efficiency+worksheet+answers PDF link annotation
