T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a link to a known malicious redirector, traffmen.ru, which is indicative of a phishing or malware distribution attempt. The document body, though heavily obfuscated, contains a reference to 'Axel from angry birds 2 voice', likely a lure to entice users to click the malicious link. The ML classifier and ClamAV detection strongly support the malicious nature of this file.

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.
