T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF document that contains an embedded URL, identified as a high-risk indicator. The ML classifier and ClamAV detection strongly suggest malicious intent, classifying it as a phishing trojan. The document body, though heavily obfuscated, appears to be a lure related to 'Counting atoms and elements worksheet answers', directing users to a suspicious URL for further action, likely to download a second-stage 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=counting+atoms+and+elements+worksheet+answers PDF link annotation
