T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a lure related to converting PDF to Word for free, indicated by the document body and the 'PDF_SEO_LINK_FARM' heuristic. It also contains numerous external links, with 'https://mezovuduw.ru/award?keyword=chuy%25E1%25BB%2583n+pdf+%25E1%25BA%25A3nh+sang+word+mi%25E1%25BB%2585n+ph%25C3%25AD' being a primary indicator of a phishing or malicious download attempt. ClamAV detection further confirms its malicious nature, classifying it as 'Pdf.Phishing.Trojan'. No scripts were extracted, but the PDF structure and embedded links strongly suggest a phishing or malware distribution vector.

Heuristics 6
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.

-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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://mezovuduw.ru/award?keyword=chuy%25E1%25BB%2583n+pdf+%25E1%25BA%25A3nh+sang+word+mi%25E1%25BB%2585n+ph%25C3%25AD
