T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a large number of external links, many pointing to PDF files hosted on services like weebly.com and f-static.net, suggesting a link farm or content distribution network for malicious content. The primary URL, trafficel.ru, is presented in a context that mimics a Hotels.com contact page, indicating a phishing or social engineering lure. ClamAV and ML classifiers strongly indicate maliciousness, specifically as a phishing or trojan distribution vehicle.

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/aws?utm_term=hotels.com+usa+contact+number
