These threads on Reddit and a Square Enix forum suggest this phishing campaign was also spread using the in-game chat feature, whisper. Attackers frequently use communication channels other than email to avoid/delay detection.
Targeted phishing attacks often follow press releases and major events like Amazon Prime Day and national holidays. The best thing users can do is slow down and closely review emails and links before clicking calls to action, entering information, or opening attachments.
