MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document was flagged as malicious by multiple heuristics, including a critical alert for a link to known malicious redirector infrastructure. The embedded URL `http://botcraftman.ru/...` is highly suspicious and likely serves as a lure to a malicious website. No scripts were extracted, but the presence of the malicious URL strongly suggests an attempt to redirect the user to a phishing or malware distribution site.

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.
