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

The PDF file contains a link that is flagged as a malicious redirector. The document body, though heavily obfuscated, appears to reference 'Gta san andreas oyun g\[...]nl\[...]' and includes the malicious URL, suggesting a lure to a fake download or game-related content. The link redirects to `https://ttraff.cc/wix?keyword=gta+san+andreas+oyun+g%25C3%25BCnl%25C3%25BC%25C4%259F%25C3%25BC`, which is classified as malicious. This indicates a phishing or social engineering attack aiming to redirect users to harmful sites.

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.
