MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that advertises a "Coin Master Hack App Link", strongly suggesting a lure for users to download potentially unwanted or malicious software. The ML classifier also flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of embedded URLs and the nature of the content indicate an attempt to redirect users to external resources for downloading applications.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
