MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is a PDF document that contains embedded URLs, one of which is a URL shortener. The ClamAV heuristic identifies it as a Pdf.Dropper.Agent, indicating it's designed to download and execute a second-stage payload. The presence of embedded URLs and the dropper classification strongly suggest a malicious intent, likely to lure the user to a compromised site via the shortened links.

  • Clickable URI uses URL shortener medium PDF_URL_SHORTENER_URI

  • 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.
