T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains heuristics indicating it is a malicious redirector and a phishing lure, specifically referencing an invoice. The embedded URL `https://traffmen.ru/aws?utm_term=broadsheet+brisbane+lunch` is flagged as malicious and likely serves as the initial stage of a phishing attack. No scripts were extracted, but the PDF structure and malicious link strongly suggest a phishing attempt.

Fake invoice / payment lure low SE_INVOICE_LUREDocument contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
-
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://traffmen.ru/aws?utm_term=broadsheet+brisbane+lunch
