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

The PDF document contains a large number of embedded links pointing to external PDF files hosted on the domain 'ieuicufioao.myhome.cx'. This heuristic firing suggests a link farm or SEO poisoning attempt, likely intended to drive traffic to malicious content or to obscure the true nature of the payload. No scripts were extracted from this sample. The primary attack pattern observed is the distribution of numerous external links within the document body.

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.
