MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links to external PDF files, many of which are hosted on the dynamic DNS domain 'loaminoo.linkpc.net'. This heuristic firing suggests a link farm or SEO manipulation tactic. While no scripts were explicitly extracted, the nature of the embedded links and the ML classifier's high confidence indicate a malicious intent, possibly to distribute further malware or engage in phishing. The document body appears to be corrupted or heavily obfuscated, preventing a direct analysis of its content.

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.
