T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF document identified as malicious by ML classifiers and ClamAV. It contains an embedded URI pointing to 'trafffi.ru', which is likely a malicious domain used for hosting or redirecting to a payload. The document body, though heavily obfuscated, contains metadata suggesting it was generated by wkhtmltopdf, and the presence of an external URI heuristic indicates an attempt to lead the user to a remote resource.

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/strik?utm_term=protein+engineering+lecture+ppt PDF link annotation
