1 trillion yen leaked from Binance, largest crypto asset exchange, North Korea involved?

Binance, the world's largest crypto asset (virtual currency) exchange business, announced on the 30th that it had suffered a cyberattack and lost crypto assets worth approximately $6.3 billion (1 trillion yen). This is the largest loss of crypto asset theft ever. It has also been pointed out that North Korea's elite hacker group was involved. Crypto assets have fallen across the board due to the huge outflow.

On the same day, Binance announced that it would ``compensate for all losses'' using a customer protection fund and its own funds. To prevent further damage, deposits and withdrawals were temporarily suspended and assets worth approximately $3 billion were frozen. Initial investigations indicate that the laptop computer of an engineer in charge of development and operations may have been hacked.

TRM Lab, an American blockchain analysis company, said it believed the attack was carried out by North Korea's elite hacker group, TraderTrater. The amount of damage is approximately four times the amount of the $1.5 billion leak that occurred in 2025 at the cryptocurrency exchange Bybit.

The U.S. Federal Bureau of Investigation (FBI) has determined that the ByBit case was committed by TraderTrater, pointing out that TRMs have the same techniques, including the fact that billions of dollars were withdrawn in about 20 minutes, and the method of executing the transactions all at once using pre-obtained signatures.
