T1566.001 Spearphishing Attachment
This PDF file was flagged by a machine learning classifier and ClamAV as malicious, with ClamAV identifying it as 'Pdf.Phishing.Trojan'. The presence of embedded URLs, though many are marked as benign, suggests a phishing or credential harvesting attempt. The heuristic 'PDF_URI' indicates an external URI was found, likely used to redirect the user to a malicious site. No scripts were extracted from this sample, but the overall structure and detection indicate a malicious intent to deceive the user.

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/razvivatel/yapz/~3/0YvHz_IItD0/square?utm_term=soar+the+breakthrough+treatment+for+fear+of+flying+pdf
