The FBI, Japan’s police force, and the U.S. Department of Defense confirmed the attack, which exploited vulnerabilities in the communications system of Ginco, an external crypto wallet company.
The hackers, posing as LinkedIn recruiters, tricked a Ginco employee into uploading compromised Python code to their personal GitHub repository.
This gave the attackers access to Ginco’s communication system, enabling them to intercept and redirect a legitimate transaction from DMM.
The massive financial loss forced DMM to shut down its operations.

The incident is part of a growing pattern of North Korean cybercrime, with groups linked to the regime responsible for $1.34 billion in stolen cryptocurrency across 47 incidents in 2024, per Chainalysis.
This represents a significant rise from $660 million stolen in 2023.
The DMM breach highlights the increasing sophistication of North Korea’s cyber operations, which exploit weaknesses in the crypto ecosystem.
It underscores the urgent need for heightened security measures in the industry to counter such evolving threats.
