MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF document that contains a URL disguised as an answer key for word problems. The embedded URL, https://nipisod.ru/strik?utm_term=system+of+inequalities+word+problems+answer+key, is highly suspicious and likely leads to a phishing or malware distribution site. ClamAV detection further supports its malicious nature.

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://nipisod.ru/strik?utm_term=system+of+inequalities+word+problems+answer+key
