SAN FRANCISCO (Reuters) - Hackers who breached casino giants MGM Resorts International and Caesars Entertainment in recent weeks also broke into the systems of three other companies in the manufacturing, retail, and technology space, a security executive familiar with the matter said.

David Bradbury, chief security officer of the identity management company Okta, said five of the company's clients, including MGM and Caesars, had fallen victim to hacking groups known as ALPHV and Scattered Spider since August.
