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

The PDF contains an embedded link to a known malicious redirector, http://botcraftman.ru/. This heuristic firing, combined with the ML classifier's high confidence, indicates a malicious intent to lure the user to a harmful site. The document body is heavily obfuscated and does not provide further context on the specific lure, but the presence of the malicious URL is the primary indicator of compromise.

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.
