T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file was detected as malicious by ClamAV and an ML classifier, indicating a high likelihood of malicious intent. The presence of an external URI pointing to 'pelibifir.ru' suggests a phishing or credential harvesting attempt, disguised as a worksheet. While no scripts were explicitly extracted, the PDF structure and embedded URLs are indicative of a phishing lure.

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://pelibifir.ru/wix?keyword=parallelogram+maze+worksheet+answers
