MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a critical heuristic firing for a malicious redirector link. The embedded URL, https://ttraff.link/wix?keyword=%25D9%2585%25D8%25A7+%25D9%2585%25D9%258A+%25D8%25B7%25D8%25A8%25D8%25B9%25D8%25A9+%25D9%2585%25D9%258A%25D8%25B2%25D9%2588%25D8%25AA%25D9%258A%25D9%2586%25D8%25AA+%25D8%259F, is identified as malicious and likely leads to a scam or phishing attempt. No scripts were extracted, but the presence of the malicious URL is sufficient evidence for this assessment.

Heuristics 2

  • 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.
  • 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.
