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. In an interview with Reuters, Bradbury didn't name the other companies, but said Okta was cooperating with official investigations into the breaches. "We've seen consistently over the past six to 12 months, a ramp up in these types of attacks," Bradbury said. Bradbury said the group had breached into MGM and obtained access to its Okta client, which allowed it further access to more credentials in the identity management firm's system. Bradbury said Mandiant's description of the group's tactics aligned with what Okta had observed in the recent hacks.
