MITRE ATT&CK

T1566.001 Spearphishing Attachment

The document contains multiple embedded URLs and a prominent lure related to game hacks and free items, strongly suggesting a phishing or malware distribution attempt. The heuristic 'SE_SECRET_RECOVERY_LURE' indicates the document may also attempt to harvest sensitive user credentials. No scripts were extracted, but the presence of external links and the lure point to a malicious intent to redirect the user to a potentially harmful site.
