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

The PDF file was flagged as a malicious redirector due to its embedded link to botcraftman.ru. This URL is known to lead to malicious infrastructure. The document body is heavily obfuscated and does not provide further clues, but the presence of a malicious redirector strongly suggests a phishing or malware delivery attempt. No scripts were extracted from this sample.

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%D1%80%D0%B5%D0%B4%D0%BD%D0%B8%D0%B9+%D0%B1%D0%B0%D0%BB%D0%BB+%D0%BF%D0%BE+%D1%84%D0%B8%D0%B7%D0%B8%D0%BA%D0%B5+%D0%B5%D0%B3%D1%8D+2015&charset=utf-8
