T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF document contains embedded URLs and is flagged by ML classifiers and ClamAV as malicious, specifically as a phishing trojan. The document body, though partially corrupted, suggests a lure related to a 'chemistry pretest with answers'. The presence of multiple external URIs indicates an attempt to redirect the user to malicious content or download further payloads.

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://bologen.ru/wix?keyword=chemistry+pretest+with+answers PDF link annotation
