T1204.002 Malicious File
The file is identified as malicious by ClamAV and an ML classifier, with a heuristic indicating a visual download button lure. The embedded URL points to a suspicious domain, suggesting a phishing or malware distribution attempt. The document body is heavily obfuscated, but the presence of a download lure and the external URL strongly indicate a malicious intent to trick the user into downloading a payload.

Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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.
