Risk and fiscal advisory remedies company Kroll on Friday disclosed that a person of its personnel fell victim to a “hugely innovative” SIM swapping attack.

The incident, which took place on August 19, 2023, targeted the employee’s T-Cellular account, the enterprise said.

“Specially, T-Cellular, without the need of any authority from or get in touch with with Kroll or its employee, transferred that employee’s phone variety to the risk actor’s phone at their request,” it said in an advisory.
