MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF file contains a heuristic firing for a 'PDF_SEO_LINK_FARM', indicating a large number of embedded external links. These links predominantly point to PDF files hosted on the 'easckaolp.myhome.cx' domain, suggesting a potential SEO spam or content distribution scheme. The document body is heavily obfuscated and unreadable, providing no further context on the specific lure. 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.
