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

It contains a large number of embedded links, identified as a 'PDF_SEO_LINK_FARM' heuristic, pointing to various PDF documents hosted on 'loaminoo.linkpc.net'. While the individual linked PDFs are currently marked as benign, the sheer volume and the nature of the heuristic suggest a potential for distributing malicious content or engaging in SEO manipulation. 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.
