T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a heuristic firing for a link farm, indicating it is designed to host numerous external links. One prominent URL, 'https://trafficel.ru/123?keyword=user+manual+samsung+galaxy+s10+plus', is embedded within the document body and presented as a user manual, suggesting a social engineering tactic. The ML classifier strongly flagged this PDF as malicious, supporting the assessment that it is part of a phishing or spam campaign.

Heuristics 4
-
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.
-
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/123?keyword=user+manual+samsung+galaxy+s10+plus
