T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was flagged as malicious by ML classifiers and ClamAV, specifically as 'Pdf.Phishing.Trojan'. It contains an embedded URL pointing to 'https://nipisod.ru/aws?utm_term=describe+the+sunspot+cycle', which is likely used to deliver a secondary payload or conduct phishing. The document body, though heavily obfuscated, contains text fragments related to the sunspot cycle and the wkhtmltopdf application, suggesting a lure.

-
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://nipisod.ru/aws?utm_term=describe+the+sunspot+cycle
