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

The PDF file contains a large number of embedded links to external PDF documents, all hosted on the suspicious domain 'loaminoo.linkpc.net'. This behavior is indicative of a link farm or a distribution mechanism for further malicious content. No scripts were extracted, and the document body was heavily obfuscated, limiting further analysis of the immediate intent beyond the link farm. The primary attack pattern observed is the mass distribution of links, likely to manipulate search engine results or to serve as a lure for users to download additional malicious files.

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.
