T1566.001 Spearphishing Attachment
The file is identified as malicious by ML classifiers and ClamAV, with a high-confidence heuristic indicating an advance-fee scam lure. The document body, though heavily obfuscated, contains metadata suggesting it was generated by wkhtmltopdf, and the presence of an external URI points to a potential phishing or scamming attempt. The primary IOC is the external URL which is likely part of the scam.

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.
