T1566.001 Spearphishing Attachment
T1059.007 JavaScript
T1203 Exploitation for Client Execution
The sample is a PDF document that uses a lure related to digital electronics questions to trick users into revealing sensitive information, as indicated by the 'SE_SECRET_RECOVERY_LURE' heuristic. The presence of external URIs and ClamAV detection further supports its malicious nature. While no scripts were explicitly extracted, the PDF structure and embedded URIs suggest it may exploit PDF vulnerabilities or lead to further malicious content, potentially involving JavaScript execution.

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=digital+electronics+questions+pdf
