T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, with a significant number pointing to Weebly-hosted PDF files, indicative of a link farm or SEO spamming operation. ClamAV and ML classifiers identified the file as malicious, specifically a phishing or trojan variant. The presence of embedded URLs and the PDF_SEO_LINK_FARM heuristic strongly suggest the document's purpose is to redirect users to potentially malicious sites.

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://trafficel.ru/strik?utm_term=borderlands+pre+sequel+weapon+codes
