T1566.001 Spearphishing Attachment
T1059.007 JavaScript
This PDF document contains a large number of external links, many of which point to other PDF files, suggesting a link farm or redirection mechanism. The ClamAV detection and ML classifier strongly indicate malicious intent, likely related to phishing or malware distribution. The presence of embedded URLs and the 'SE_INVOICE_LURE' heuristic suggest the document is designed to trick users into clicking malicious links, potentially leading to the download of a second-stage payload.

-
Fake invoice / payment lure low SE_INVOICE_LUREDocument contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
-
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://pixomot.ru/wb?keyword=5th%20grade%20area%20and%20perimeter%20worksheets%20grade%205
