Social engineering attack on cloud gaming firm Shadow exposes customer data
French cloud gaming company Shadow told customers that an employee was tricked via Discord and a fake Steam game in late September 2023, letting attackers reach customer data at a SaaS provider. A hacker claimed to be selling data on more than 530,000 customers, which Shadow did not dispute.
