T1566.001 Spearphishing Attachment
The PDF file was detected as malicious by ClamAV and an ML classifier, indicating a phishing attempt. The heuristic 'PDF_SEO_UTM_REDIRECTOR_LINK' specifically points to an image lure designed to redirect users to a phishing site via a Google feedproxy URL. No scripts were extracted, but the presence of embedded URLs and the nature of the heuristics suggest a phishing attack pattern.

Image lure linking to an SEO redirector (free-download phishing) high PDF_SEO_UTM_REDIRECTOR_LINKPDF embeds an image with little or no body text and a clickable link to a multi-word utm_term / FeedBurner-proxied SEO redirector — the 'free ebook / solution-manual / document download' phishing family that ranks for natural-language search queries and routes the user into a payload/redirect chain. The PDF carries no exploit; the risk is the linked destination. Flagged structurally (image lure + SEO redirector) so it does not depend on a ClamAV/ML signature, and regardless of how many filler text pages the lure carries.

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://feedproxy.google.com/~r/sq/ugae/~3/7R6buoffwiA/square?utm_term=can+you+go+to+uni+without+level+3 PDF link annotation
