T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF document contains an embedded URI pointing to a suspicious domain, identified as a phishing attempt by ClamAV and a machine learning classifier. The document body, though heavily obfuscated, suggests a lure related to 'workbook answers', aligning with a phishing pretext. No scripts were extracted, but the presence of a malicious URI is a high-confidence indicator of malicious intent.

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=measuring+up+workbooks+answers PDF link annotation
