According to the division, the two exploited a system in My Page used by customers of competitors that allows them to log in using their postal code or date of birth if they forget their ID or other information. They called customers pretending to be a representative, asked for their postal code and other information, and then gained unauthorized access to their My Pages. After understanding customers' contract plans, options, and monthly fees, they solicited them to switch contracts.

The division suspects that the two may have used similar techniques to gain unauthorized access to approximately 3,700 customer information over the three years up to March of this year, leading to approximately 2,500 contract changes.
