T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is identified as malicious by ClamAV and an ML classifier, with heuristics indicating embedded external URIs. The document body, though heavily obfuscated, suggests a lure related to a 'business email writing course' and contains metadata from wkhtmltopdf, indicating it was likely generated from web content. The presence of numerous embedded URLs, many of which are suspicious, points towards a phishing or credential harvesting attempt, likely involving the download of further malicious content.

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://druttle.ru/award?keyword=business+email+writing+course+pdf
