MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.001 PowerShell

The PDF document contains a large number of embedded links, identified as a PDF_SEO_LINK_FARM heuristic. The document body, though heavily obfuscated, contains numerous URLs pointing to loaminoo.linkpc.net, suggesting a link farm or distribution mechanism. The primary attack pattern appears to be SEO manipulation or the distribution of further malicious content via 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.
