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

The PDF file contains an embedded link that points to a known malicious redirector. This suggests the document is designed to lure users to a harmful website, likely for phishing or malware delivery. No scripts were extracted, and the document body was not readable, limiting further analysis of the exact lure.

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 http://botcraftman.ru/?lip&keyword=%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D0%BC%D1%83%D0%BB%D1%8C%D1%82%D1%84%D0%B8%D0%BB%D1%8C%D0%BC+%D0%B4%D0%B8%D0%BD%D0%BE%D0%B7%D0%B0%D0%B2%D1%80+%D1%87%D0%B5%D1%80%D0%B5%D0%B7+%D1%82%D0%BE%D1%80%D1%80%D0%B5%D0%BD%D1%82&charset=utf-8
