T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was flagged as malicious by multiple heuristics, including a critical alert for a redirector link to 'traffmen.ru'. The ML classifier also assigned a high probability of maliciousness. Although no scripts were explicitly extracted, the presence of a malicious redirector URL strongly suggests a phishing or credential harvesting attempt, likely delivered as a spearphishing attachment.

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/123?utm_term=common+size+income+statement+problems+and+solutions
