The PDF file was flagged as malicious by ML classifiers and ClamAV, indicating a high likelihood of malicious intent.

The document body, though partially obfuscated, references 'USMLE first aid 2020 vs 2021', likely a lure to entice users to click the malicious link.

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.
