MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The document uses a social engineering lure, presenting itself as a cheat for a popular game and instructing the user to install a browser extension or download a file. The presence of an external URI pointing to a suspicious domain, combined with heuristics indicating a browser installation lure and a visual download button, strongly suggests a malicious intent to trick the user into downloading a payload. No scripts were extracted from this sample.
