A group of South Koreans, who were found running an illegal derivatives-trading website, were indicted for breaking the national security law after being accused of providing hacking software to North Korean hackers in return for 140 million pieces of personal information.
The Seoul central prosecutor’s office said the website’s managers identified as 28-year-old Choi and 34-year-old Kim were charged with having been in contact with North Korean hackers in China and the creation and sale of an illegal program after receiving a large number of personal information and malware.
Choi was placed into custody while Kim along with two other conspirators were indicted without being arrested.
Choi had been in contact with North Korean hackers from 2004 until March last year and received malware files to be used in DDOS attacks, later attacking company websites with those codes. Choi was also charged with having handed over hacking tools to the North Koreans.
Futhermore, Choi was also found to have pocketed roughly 1.3 billion won in profits by running a derivatives-trading website created by the North Korean hackers.
South Korean prosecutors said Choi handed over some of his profits to the North Korean hackers, contributing to Pyongyang’s offshore efforts to earn U.S. dollars. Choi also infiltrated South Korean websites, aware his actions could later lead to cyber-terrorism, prosecutors said.
