T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a large number of external links, identified as a 'PDF_SEO_LINK_FARM' heuristic, suggesting an attempt to direct users to malicious websites. The ClamAV detection and ML classifier further indicate malicious intent, specifically classified as 'Pdf.Phishing.Trojan'. The presence of embedded URLs and the 'SE_PASSWORD_ARCHIVE_LURE' heuristic suggest the document is designed to trick users into downloading further malicious content, possibly by providing instructions for password-protected archives.

Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LUREDocument gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
-
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://ponafet.ru/123?utm_term=100+cerebro+libro+pdf
