MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

This PDF document employs social engineering tactics, specifically a 'free game hack' lure, to entice users to click on a link. The primary link redirects to a malicious URL, suggesting the document's purpose is to lead users to potentially harmful content or further malware. The PDF structure and embedded URLs indicate a malicious intent to exploit user interest in game cheats for malicious purposes.

Heuristics 5

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.
ClickFix social engineering attack high SE_CLICKFIX

Document instructs the user to press Win+R or paste a command into a terminal — consistent with ClickFix attacks that bypass macro restrictions by tricking users into running malicious commands directly
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.
