T1566.001 Spearphishing Attachment
T1059.007 JavaScript
This PDF file was identified as malicious by multiple heuristics and an ML classifier, specifically flagged for containing a large number of external links, characteristic of a link farm. The primary URL, https://trafffe.ru/123?utm_term=slim+x+genie+keto+shark+tank, suggests a potential phishing or scam attempt related to weight loss products. No scripts were extracted, but the PDF structure itself facilitates the redirection to these external sites.

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=slim+x+genie+keto+shark+tank
