Although the number of attacks decreased, their total cumulative theft has reached $6.75 billion. North Korean hackers managed to steal more cryptocurrency with fewer attacks, often by infiltrating crypto services with IT personnel or using sophisticated impersonation tactics targeting executives.

After major thefts, their laundering cycle averages about 45 days. In 2025, personal wallet thefts surged to 158,000 cases, affecting 80,000 users. However, the total stolen value ($713 million) decreased compared to 2024.
