T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF contains a critical heuristic firing indicating a malicious redirector link to 'https://ttraff.me/wix?keyword=me+and+the+key+2+level+22'. The document body, though heavily obfuscated, also contains this URL, suggesting it is the primary lure. The ML classifier also flagged this PDF with high confidence. The presence of embedded URLs and the nature of the redirector strongly suggest a phishing or malware delivery attempt.

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.
    URL https://ttraff.me/wix?keyword=me+and+the+key+2+level+22
