MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded links and text referencing game cheats and free items for popular games like Roblox and Coin Master, indicating a lure for users seeking such content. The heuristic 'PDF_MALICIOUS_REDIRECTOR_LINK' confirms that the primary URL http://netcdn.co/app/431946152/roblox.hack.balance-game-hack leads to known malicious infrastructure. Although no scripts were extracted, the presence of malicious links and the ML classifier's high confidence suggest the document is designed to redirect users to a malicious site for further exploitation or malware delivery.

Heuristics 3

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

  • 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
  • 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.
