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

The PDF file contains embedded JavaScript and a critical heuristic firing for a malicious redirector link pointing to botcraftman.ru. This suggests the document is designed to redirect users to a malicious site, likely for further exploitation or phishing. The presence of embedded JS further supports the malicious intent.

Heuristics 3

  • 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 JS stream low PDF_JS
    PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
  • 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.
