MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious File

The document presents itself as a "Toolbox For Minecraft Windows 10" and contains embedded URLs that lead to download sites, suggesting a lure for users to download potentially malicious software. The heuristic 'SE_CLICKFIX' indicates the document likely instructs the user to execute commands, a common social engineering tactic to bypass security measures. The presence of embedded URLs and the ML classifier's high confidence score support the assessment of malicious intent.

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.
