T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a heuristic firing for PDF_SEO_LINK_FARM, indicating it's part of a link farm designed to generate traffic and potentially host malicious content. The embedded URL points to a suspicious domain, and ClamAV detection confirms its malicious nature as a phishing trojan. The document body, though heavily obfuscated, suggests a lure related to educational content to entice clicks on the external link.

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://soxebez.ru/strik?utm_term=bill+of+rights+worksheet+answers+key PDF link annotation
