FBI Unveils How North Korean Hackers Stole $300 Million from DMM Crypto Exchange

by

As a seasoned analyst with over two decades of experience in the cybersecurity industry, I’ve seen my fair share of digital heists, but the recent $305 million crypto theft from DMM by North Korea-affiliated hackers, TraderTraitor, is nothing short of impressive. Their use of sophisticated tactics, including posing as recruiters on LinkedIn and employing social engineering attacks, showcases a level of ingenuity that should give even the most vigilant organizations pause.

This year in May, the FBI released a report detailing that cybercriminals originating from North Korea managed to steal an impressive $305 million from the Japanese cryptocurrency exchange, DMM.

On Monday, December 23rd, the FBI, the Department of Defense Cyber Crime Center (DC3), Japan’s National Police Agency (NPA), and other agencies published a report detailing a cyberattack in which hackers made off with approximately 4,502.9 Bitcoin, which was valued at around $305 million at that time.

As a crypto investor, I’ve come to learn that the theft I recently experienced was allegedly orchestrated by TraderTraitor, a cybercrime group linked to North Korea. Moreover, it’s been reported that this group employs advanced strategies, such as carefully planned social engineering attacks on company employees, to carry out their heists.

As an analyst, I’ve recently uncovered some troubling news. It appears that North Korean entities, in collaboration with international partners, have executed a crypto heist from a Japanese company. The initial point of entry was a clever social engineering maneuver, following which the cyber actors deployed TraderTraitor malware to pilfer cryptocurrency valued at approximately $308 million.

FBI – North Korean Hackers Pretended as Recruiters

According to an FBI probe, a North Korean cybercriminal assumed the role of a recruiter on LinkedIn in March, focusing on an individual at the Japanese cryptocurrency wallet firm Ginco. Subsequently, this hacker transmitted a harmful link to the employee, disguised as a pre-employment assessment located on a GitHub webpage. Believing it was genuine, the employee pasted the code into their own GitHub account, thereby putting their system at risk.

By May, hackers linked to TraderTraitor group successfully exploited the pilfered data by pretending to be an employee and infiltrating Ginco’s internal messaging system. According to the FBI, it is believed that these intruders then utilized this access to alter a legitimate Bitcoin transaction request from a DMM employee, leading to the theft of approximately $300 million worth of Bitcoins.

Afterward, the thieves moved the pilfered assets into accounts managed by the TraderTraitor collective. The FBI announced their intent to collaborate with Japan’s National Police Agency (NPA) and global allies in order to unmask and counteract the illicit operations of North Korean cybercriminals.

Crypto Hacks on the Rise

In 2024, the significant DMM hack was just one instance in a series of numerous cybersecurity issues that occurred throughout the year. As detailed in a December 19 report by Chainalysis, these incidents amounted to a staggering 303 in total, with potential losses reaching as high as $2.2 billion.

As a crypto investor, I’ve been closely watching the rise in cybersecurity incidents within the centralized finance (CeFi) sector. It’s alarming to see that these occurrences have skyrocketed by an astounding 1,000% compared to last year, according to the insights from Cyvers. This underscores the increasing vulnerabilities in both centralized and decentralized finance systems, as cyber threats are constantly mutating into more sophisticated forms. It’s a reminder for all of us to stay vigilant and prioritize security measures in our investment strategies.
