T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document employs social engineering tactics, including a fake CAPTCHA and a browser extension installation lure, to trick users into downloading a payload. The embedded URL, http://netcdn.tw/app/1094591345/pokemon-go-free-quest-game-hack, likely leads to the malicious download. The document body's content and the heuristics strongly suggest a phishing or malware distribution attempt.

Heuristics 6

  • Fake CAPTCHA / human verification prompt high SE_FAKE_CAPTCHA

  • 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
