MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious File

The document contains lures for game cheats and virtual currency, directing users to external URLs. A high-confidence heuristic indicates the document attempts to trick the user into copying and pasting content into a command-line interface, likely to download and execute a secondary payload. No scripts were extracted, but the presence of embedded URLs and the clipboard command lure strongly suggest a malicious workflow.
