T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is identified as malicious by ML classifiers and ClamAV, specifically flagged for brand-impersonation credential phishing. It contains embedded URLs, one of which, 'https://najagoji.weebly.com/uploads/1/3/6/0/136082188/3762953.pdf', is associated with a phishing lure. The document body, though heavily obfuscated, contains metadata suggesting it was generated by wkhtmltopdf, and the presence of PDF-specific heuristics indicates it's a PDF document designed to exploit users.

Brand-impersonation credential phishing lure critical SE_BRAND_CREDENTIAL_PHISHDocument impersonates a well-known consumer brand and uses account-security / verification language ('unusual activity', 'account on hold', 'verify your account') to steer the reader to a credential-harvesting link. Corroborated by: action link to abused redirector https://najagoji.weebly.com/uploads/1/3/6/0/136082188/3762953.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://jottigo.ru/123?utm_term=report+on+english+debate+competition+in+school PDF link annotation
