T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains an embedded URI pointing to a suspicious domain, identified by ClamAV as a phishing trojan. The document body, though heavily obfuscated, appears to be a lure related to a 'two phase simplex method example', likely intended to trick the user into visiting the malicious URL. The ML classifier also strongly indicated maliciousness.

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=two+phase+simplex+method+example
