T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was flagged by a machine learning classifier and ClamAV as malicious, with ClamAV identifying it as Pdf.Phishing.Trojan. The presence of an external URI pointing to 'trafficel.ru' suggests a phishing attempt, likely to trick users into believing it is related to academic materials. No scripts were extracted, but the PDF structure and embedded URLs indicate a malicious intent to redirect users to potentially harmful content.

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://trafficel.ru/123?utm_term=2014+ap+calculus+bc+free+response+5
