MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links to external PDF files hosted on the domain 'easckaolp.myhome.cx'. This heuristic firing suggests a link farm, likely intended to manipulate search engine results or distribute malicious content. While no scripts were explicitly extracted, the nature of the embedded links and the ML classifier's high confidence indicate malicious intent, possibly involving the exploitation of PDF vulnerabilities or social engineering to trick users into visiting these links.

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.
