The theft of 4,502.9 bitcoin (BTC), which is forcing the exchange to close, was “affiliated” with a group known as TraderTraitor, the FBI said in a statement with the Department of Defense Cyber Crime Center and National Police Agency of Japan.
Hackers linked to North Korea dominated crypto crime this year, Chainalysis said in its annual report on the subject. The country, whose official name is the Democratic People’s Republic of Korea (DPRK), is tied to more than half of the crypto value stolen in 2024. Its operatives are responsible for the theft of $1.34 billion across 47 incidents, more than double the $660 million (a figure revised down from an initial estimate) taken last year.
TraderTraitor, also known as Jade Sleet, UNC4899 and Slow Pisces, generally works by targeted social engineering, according to the statement. In this case, malicious code was inserted into a Python script used in a fictitious pre-employment test and sent by an operative posing as a recruiter on LinkedIn to a candidate who worked at an outside enterprise, crypto wallet company Ginco.
The victim copied the code to their personal Github page, giving TraderTraitor access to session cookie information that allowed it access to Ginco’s communications system. Months later, it probably used the access to intercept a legitimate transaction request by a DMM employee, leading to the theft, the agencies said.
