MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The file is identified as malicious by a ClamAV signature and an ML classifier, indicating a high likelihood of malicious intent. The embedded URL, 'https://leonvi.ru/award?keyword=eenadu+news+paper+telangana+pdf+download', suggests a phishing or social engineering lure, likely intended to trick the user into downloading further malware or visiting a malicious site. No scripts were extracted, but the PDF structure and embedded URI are strong indicators of a phishing attempt.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL
    The 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_URL
    One 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.
