T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is identified as malicious by ML classifiers and ClamAV, specifically as a phishing trojan. The embedded URL, 'https://traffine.ru/aws?utm_term=recommendation+letter+for+college+format', suggests a social engineering lure related to college recommendations. Although no scripts were explicitly extracted, the PDF structure and the presence of embedded URLs indicate a phishing attempt, likely leveraging a PDF exploit or social engineering to redirect the user to the malicious site.

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://traffine.ru/aws?utm_term=recommendation+letter+for+college+format
