T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, with a critical heuristic identifying it as a "PDF_SEO_LINK_FARM". One of the primary external links, https://ketchas.ru/pbw?utm_term=kettlebell+fat+loss+program+pdf, suggests a lure related to a fitness program. The ClamAV detection and ML classifier strongly indicate malicious intent, likely phishing or a scam. No scripts were extracted, but the PDF structure itself is used to host a large number of external links.

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://ketchas.ru/pbw?utm_term=kettlebell+fat+loss+program+pdf
