T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was flagged as malicious by a ML classifier and ClamAV, indicating a high likelihood of malicious intent. The embedded URL `https://traffking.ru/strik?utm_term=marine+biology+castro+8th+edition` is suspicious and likely leads to a phishing or malware distribution site. The document body, though heavily obfuscated, contains references to 'Marine biology castro 8th edition' and authoring application details, suggesting a lure to disguise the malicious URL.

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.

Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://traffking.ru/strik?utm_term=marine+biology+castro+8th+edition
