MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious Link

The PDF file contains a critical heuristic firing indicating a redirect to known malicious infrastructure. The embedded URL `http://botcraftman.ru/?lip&keyword=%D1%85%D0%B8%D0%BC%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B8%D0%B9+%D1%81%D0%BE%D1%81%D1%82%D0%B0%D0%B2+%D0%BC%D0%BE%D0%BB%D0%BE%D0%BA%D0%B0+%D1%82%D0%B0%D0%B1%D0%BB%D0%B8%D1%86%D0%B0&charset=utf-8` is the primary indicator of malicious intent. This suggests the document is designed to lure the user to a compromised or malicious site, likely for phishing or further malware delivery.

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.
