Square Enix Members hack affected 1.8 million

Square Enix has confirmed up to 1.8 million users could be affected by a hack affecting the company's Members scheme.

The publisher said earlier this morning that "unknown parties" had gained "unauthorized access" in relation to a Square server that belonged to the SEM service in North America and Japan, with operation suspended at the time.

The publisher has since said to France24 that up to 1 million Japanese users and 800,000 US users may have had personal details compromised, but Square insists there isn't a worry of credit card details getting out due to not storing that particular data.

The 300,000 accounts that formed the European arm of Square Enix Members remained unaffected.

"We are yet to learn whether illegal access was gained to our clients' information," said a Square rep. "But we have asked our customers to be aware of the incident in case they receive suspicious messages using our name."
