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

The PDF file contains a large number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic. These URLs point to various book titles hosted on the 'loaminoo.linkpc.net' domain. While the individual URLs are currently marked as benign, the sheer volume and the nature of the heuristic suggest a malicious intent, likely for SEO manipulation or to redirect users to potentially harmful content. No scripts were extracted from this sample.

  • 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.
