T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a large number of external links, many pointing to other PDFs, indicative of a link farm or phishing lure. The heuristic 'PDF_SEO_LINK_FARM' specifically flags this behavior, and the ClamAV detection 'Pdf.Phishing.Trojan-d2528dad23a95d95-d2528dad23a95d95-10044376-0' strongly suggests a phishing or malicious intent. The document body, though heavily obfuscated, contains text related to 'instructions', aligning with a lure. No scripts were extracted, but the extensive link farm suggests the primary goal is to redirect the user to malicious content.

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.

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://trafffe.ru/123?utm_term=my+first+trampoline+instructions
