It was discovered that 30 million customer data that should have been recovered by paying 25 million yen continued to be sold in the black market
30 million customer data of T-Mobile, a major telecommunications carrier operating in Europe and North America, was stolen by a hacker group and paid 200,000 dollars (about 25 million yen) to purchase exclusive access rights. Nevertheless, it turned out that it continued to be sold in the black market.
T-Mobile Secretly Bought Its Customer Data from Hackers to Stop Leak. It Failed.
According to the news site VICE, T-Mobile was asked by the hacker group to purchase customer data for 6 BTC (about 30 million yen) in August 2021. T-Mobile asks a third party to take action to prevent the database from being misused. A third-party organization purchases a sample for $ 50,000 (about 6.3 million yen) using the intermediary function of the hacker forum Raid Forums. I also paid about 150,000 dollars (about 19 million yen) to purchase the whole, but it seems that the data continued to be sold.
The data leak was reported in August 2021 and mentions the existence of users who actually sell 30 million data.

According to VICE, T-Mobile did not comment on this matter. The reason why the third party bought the data was that it tried to take a tactic called 'hacking back' to try an aggressive counterattack against the hacker after confirming which data was stolen. VICE is guessing.
The domain of the hacker forum Raid Forums was seized by the US authorities and was forced to close.
