MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 User Execution: Malicious File

The document presents itself as a download for a game, likely Minecraft, and contains numerous URLs pointing to similar download lures. The 'ClickFix' heuristic indicates the document attempts to trick the user into executing commands, suggesting a social engineering tactic to bypass security measures and download a payload. While no scripts were directly extracted, the embedded URLs and the nature of the 'ClickFix' heuristic strongly suggest the PDF is designed to facilitate the download and execution of malicious content.

Heuristics 4

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.
