According to the government’s complaint, Rei Ishii, an employee of Sony Life Insurance Company Ltd. (“Sony Life”) in Tokyo, allegedly diverted the $154 million when the company attempted to transfer funds between its financial accounts. Ishii allegedly did this by falsifying transaction instructions, which caused the funds to be transferred to an account that Ishii controlled at a bank in La Jolla, California. Ishii then quickly converted the funds to Bitcoin cryptocurrency, the complaint said.
