T1566.001 Spearphishing Attachment T1059.007 JavaScript

This PDF file was flagged as malicious by multiple heuristics, including a critical alert for linking to known malicious redirector infrastructure. The embedded URL, 'https://gettraff.ru/wb?keyword=love%20actually%20glasgow%20theme%20sheet%20music', likely serves as a lure to a phishing or malware distribution site. While no scripts were explicitly extracted, the PDF structure and the malicious URL strongly suggest an attempt to redirect the user to a harmful destination.

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
  • 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.
