T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a heuristic indicating a link farm and an embedded URI pointing to 'dafemum.ru'. This suggests the document is designed to redirect users to a malicious site, likely for phishing or to serve a secondary payload. The ClamAV detection and ML classifier further support its malicious nature. No scripts were extracted, but the presence of external links and the overall structure point towards a phishing or malware distribution attempt.

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.

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://dafemum.ru/strik?utm_term=why+won%2527t+my+turtle+beach+recon+200+headset+work
