MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicated maliciousness, and the document body contains numerous links to external sites offering 'free spins' or 'hacks' for games like Coin Master and Roblox. These links, such as http://netcdn.co/app/406889139/free-spin-links-coin-master-october-30-2021-game-hack, likely lead to the download of unwanted applications or further phishing attempts. No scripts were extracted from this sample.
