T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF document that contains an embedded URL, identified as malicious by ClamAV and ML classifiers. The document body, though heavily obfuscated, suggests a lure related to educational material ('Net ionic equation worksheet 10-4 answers'). The primary IOC is the external URI pointing to a suspicious domain, likely intended to deliver a secondary payload or lead to a phishing page.

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://jottigo.ru/123?utm_term=net+ionic+equation+worksheet+10-4+answers PDF link annotation
