MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file was flagged by an ML classifier as malicious and contains a large number of embedded links, identified as a PDF SEO link farm. These links predominantly point to external PDF files hosted on the `loaminoo.linkpc.net` domain. While the document body itself is unreadable due to encoding issues, the heuristic findings strongly suggest the document's purpose is to distribute malicious links or engage in SEO spam, potentially leading users to phishing or malware sites.

  • 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.
