MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document employs social engineering tactics by presenting a fake CAPTCHA and a 'game hack' lure to trick users into clicking malicious links. The primary link, http://netcdn.tw/app/1094591345/pokemon-go-free-team-change-game-hack, is associated with a game hack generator, suggesting the document aims to deliver a payload or lead the user to a credential harvesting page. The presence of multiple similar PDF links further reinforces this malicious intent.

Heuristics 7

PDF links to a 'free generator / game hack' redirector high PDF_GAME_HACK_REDIRECT_LURE

PDF's clickable action targets a redirector of the form /app/<id>/<slug>-game-hack — the landing-page shape of a large SEO 'free spins / generator / game hack' lure family that funnels victims through rotating disposable hosts to a malware/scam payload. The multi-link variants also trip ML/link-farm rules; this catches the single-link variants that otherwise score clean.
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.
