MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file was identified as malicious by an ML classifier and contains a large number of embedded external links. The heuristic 'PDF_SEO_LINK_FARM' indicates that these links are likely part of a link farm, a common technique for SEO manipulation or to host malicious content. While the specific intent of the links is not fully clear from the provided data, the sheer volume and nature of the links suggest a malicious purpose, possibly to distribute further malware or engage in phishing. No scripts were extracted from this sample.

Heuristics 2

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • 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.
