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

The PDF file was flagged as a malicious redirector due to an embedded link pointing to botcraftman.ru. This URL is known to be associated with malicious infrastructure. The document body content is not human-readable and appears to be corrupted or encoded, providing no further context on the intended lure. No scripts were extracted from this sample. The primary threat is the malicious URL, which likely serves as a gateway to a phishing or malware download page.

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%B6%D0%B8%D0%B2%D0%BE%D0%B9+%D0%B0%D0%BA%D0%B2%D0%B0%D1%80%D0%B8%D1%83%D0%BC+%D0%BD%D0%B0+%D1%80%D0%B0%D0%B1%D0%BE%D1%87%D0%B8%D0%B9+%D1%81%D1%82%D0%BE%D0%BB+%D0%B1%D0%B5%D1%81%D0%BF%D0%BB%D0%B0%D1%82%D0%BD%D0%BE+%D0%B2%D0%B8%D0%BD%D0%B4%D0%BE%D0%B2%D1%81+7&charset=utf-8
