T1566.001 Spearphishing Attachment
The file is a PDF document flagged by multiple heuristics, including a high-confidence ML classifier and ClamAV, as malicious. The heuristic 'SE_ADVANCE_FEE_SCAM_LURE' indicates the document's content is designed to trick users into paying fees to receive a non-existent prize or parcel. An external URI, 'https://trafffe.ru/strik?utm_term=du+law+apparel', was extracted, which is likely part of the scam infrastructure.

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.
