T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF containing an embedded URL that points to a suspicious domain, identified by ClamAV as a phishing trojan. The document body, though heavily obfuscated, contains text related to a "certified dental technician exam", suggesting a phishing lure. No scripts were extracted, but the presence of an external URI and the ML classification strongly indicate malicious intent.

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.
