T1566.001 Spearphishing Attachment
The ML classifier and ClamAV detection strongly indicate malicious intent. The PDF contains embedded URLs, one of which is a Google feed proxy, suggesting an attempt to redirect the user to a potentially malicious site. While no scripts were explicitly extracted, the PDF structure and heuristic firings point towards a phishing or credential harvesting attempt.

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/mHcMeCcfVl0/square?utm_term=highest+paying+doctorate+degrees
