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

The PDF file was flagged as a malicious redirector due to the presence of a link to botcraftman.ru. This URL is known to be associated with malicious activities, likely serving as a gateway to further malicious content or phishing pages. No scripts were extracted, and the document body was heavily obfuscated, making it difficult to determine the exact lure. The primary threat stems from the malicious URL embedded within the document.

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.
