T1566.001 Spearphishing Attachment T1204.002 Malicious File

The PDF document contains heuristics indicating it presents a fake CAPTCHA and a lure to install a browser extension or download a file. The document body, though heavily obfuscated, contains a URL that likely leads to a malicious payload. These elements suggest a social engineering attack aimed at tricking the user into downloading and executing malware.

Heuristics 6

  • Fake CAPTCHA / human verification prompt high SE_FAKE_CAPTCHA
    Document displays a fake CAPTCHA or human-verification prompt — used to trick users into running commands or pressing keyboard shortcuts
  • Payment redirection / bank-detail change lure high SE_PAYMENT_REDIRECT_LURE
    Document describes new or changed bank, wire, ACH, IBAN, SWIFT, or routing instructions — a high-value business-email-compromise pattern
  • Browser extension / update installation lure high SE_BROWSER_INSTALL_LURE
    Document tells the user to install a browser extension, plugin, viewer, or browser update to view content — a common social-engineering path for credential theft and malware installation
  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
