MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous URLs and text related to 'Roblox Cheats' and 'free Robux', indicating a lure for users to download potentially unwanted or malicious software. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports this assessment. While no scripts were explicitly extracted, the document's structure and content suggest it's designed to facilitate the download of a second-stage payload.

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