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

The PDF file was flagged by a machine learning classifier and contains a critical heuristic indicating a malicious redirector link. The embedded URL, https://ttraff.ru/pify?keyword=sharif+badmash+south+movie, is the primary indicator of malicious intent, likely serving as a lure to a phishing or malware distribution page. No scripts were extracted, but the presence of the malicious URL and the ML classification strongly suggest a social engineering 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.
