T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF file contains a lure related to a 'real life simulator game online' and embeds a URL pointing to 'traffine.ru'. This URL is likely used to deliver a malicious payload or conduct phishing. The ML classifier and ClamAV detection strongly indicate malicious intent, consistent with a phishing or malware distribution campaign.

  • 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.
    URL https://traffine.ru/strik?utm_term=real+life+simulator+game+online
