T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains an embedded URI pointing to a malicious domain, identified by both heuristics and ClamAV as a phishing/trojan. The document body, though heavily obfuscated, suggests a lure related to a 'critical value calculator'. The presence of an external URI indicates an attempt to redirect the user to a potentially harmful site, likely for credential harvesting or malware delivery.

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.
