MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file was flagged by a machine learning classifier as malicious and contains a large number of external links to PDFs hosted on the domain 'weisncio.myhome.cx'. This suggests a link farm or SEO poisoning attack, likely intended to drive traffic to malicious content or to host further stages of an attack. No scripts were extracted, and the document body was unreadable, but the heuristic firings strongly indicate a malicious intent to redirect users.

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.
