T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is identified as malicious by a ClamAV detection and an ML classifier, indicating a high likelihood of malicious intent. The presence of an external URI pointing to 'mezovuduw.ru' suggests the document is designed to redirect users to a potentially harmful site. The document body, though heavily obfuscated, contains text related to 'traumatic brain injury pdf' and 'wkhtmltopdf', indicating a lure to disguise the malicious nature of the PDF.

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://mezovuduw.ru/award?keyword=que+es+traumatismo+craneoencefalico+pdf
