T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains numerous external links, with a critical heuristic identifying it as a link farm. One prominent URL, 'https://trafffi.ru/123?utm_term=east+coast+appliances+scratch+and+dent', suggests a lure related to appliance sales, likely a phishing or scam. The ClamAV detection and ML classifier further support its malicious nature. No scripts were extracted, but the structure and embedded links point towards a phishing or redirection attack.

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://trafffi.ru/123?utm_term=east+coast+appliances+scratch+and+dent
