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

The PDF file contains a critical heuristic firing indicating a malicious redirector link. The embedded URL 'https://ttraff.ru/pify?keyword=albie+sachs+pdf' is the primary indicator of malicious intent. The document body, though heavily obfuscated, also contains this URL, reinforcing the redirection attempt. No scripts were extracted, but the presence of a malicious URL is sufficient to classify this as a redirection-based attack.

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.
