MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of embedded links to external PDF documents hosted on the domain 'weisncio.myhome.cx'. This technique is often used for SEO poisoning or to distribute malicious content indirectly. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass external PDF link farm, with 23 links found, 21 of which use numeric slugs, suggesting a coordinated effort to direct users to potentially harmful content. 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.
