MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links to external PDF files hosted on the domain 'kiteeearpdf.myhome.cx'. This is indicative of a link farm or SEO poisoning attack, designed to drive traffic or distribute further malicious content. While no scripts were explicitly extracted, the presence of numerous external links suggests an attempt to redirect the user, potentially leading to a secondary payload or phishing attempt. The ML classifier also strongly flagged this PDF as malicious.

  • 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.
