MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file was identified as malicious due to a critical heuristic firing for a PDF SEO link farm. It contains numerous embedded URLs, all pointing to the same domain 'easckaolp.myhome.cx', suggesting a coordinated effort to distribute malicious or phishing content. No scripts were extracted from this sample, and the document body was unreadable, so the rationale is based solely on the link farm heuristic and the embedded URLs.

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.
