This PDF file was flagged as malicious by multiple heuristics, including ClamAV and an ML classifier. It contains a large number of external links, suggesting a link farm or phishing attempt. The primary URL, https://smidgel.ru/pbw?utm_term=20+free+followers+instagram+trial, appears to be part of a lure to drive traffic to potentially malicious content hosted on various platforms like Weebly and s123-cdn-static.com.

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://smidgel.ru/pbw?utm_term=20+free+followers+instagram+trial
