T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF containing an embedded URI pointing to a suspicious domain, identified by ClamAV as Pdf.Phishing.Trojan. The document body, though heavily obfuscated, contains text related to 'genetics problems' and 'worksheet answers', suggesting a lure to trick users into visiting the malicious URL. The presence of embedded URLs and the ML classifier's high confidence score indicate a malicious intent, likely for phishing or to serve a secondary payload.

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://traffnew.ru/123?utm_term=genetics+problems+abo+blood+groups+worksheet+answers PDF link annotation
