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

The PDF contains a large number of embedded links pointing to external PDF files hosted on the domain 'laoieoa.myhome.cx'. This pattern is indicative of a link farm designed to drive traffic or potentially host malicious content. The ML classifier strongly supports the malicious verdict. No scripts were extracted, and the document body was heavily obfuscated, but the presence of numerous external links is the primary indicator of malicious intent.

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.
