[Regnum] The South Korean authorities suspected the North Korean hacker group Lazarus of hacking the country's judicial system and withdrawing over a thousand gigabytes of data over two years. The Yonhap agency reported this on May 11, citing law enforcement agencies.
An unknown organization, presumably Lazarus, hacked the computer networks of South Korean courts on January 7, 2021. Data in the amount of 1.14 thousand GB were pumped from the courts’ information systems to eight servers, including foreign ones, until February 9, 2023.
The hacker attack was investigated by the National Police Investigation Department, the National Intelligence Service and the Prosecutor's Office. Law enforcement officers managed to identify the data of about 5.2 thousand files with a volume of 4.7 GB, which were stored on one of the servers in South Korea. These turned out to be files with personal information, including financial and medical information, passport data and information about military service, only 0.5% of the total volume of the leak.
The backup storage period on the remaining servers has expired and the data has been deleted. It is possible that the hack occurred even before 2021 and the damage from it could be greater.
The agency notes that Supreme Court specialists who manage the computer network began their own investigation in February 2023, but the police became fully involved in the proceedings only after reports of the hack appeared in the media.
It is also indicated that the judicial information system in South Korea was hacked for the first time. The authorities intend to strengthen control over the use of personal computers, USB drives and the Internet in courts, as well as expand staffing and purchase additional equipment to protect information.
As Regnum reported, the United States previously accused the hacker group Lazarus of attacks on its energy companies, as well as companies in Canada and Japan. In September 2022, The Wall Street Journal reported on a special operation by US intelligence agencies that resulted in the confiscation of more than $30 million in cryptocurrency. The cryptocurrency was allegedly stolen by the North Korean-linked hacker group Lazarus.
According to Chainalysis experts, from January to July 2022, hackers stole $1.9 billion worth of cryptocurrency. At the same time, North Korean hackers, including the hacker group Lazarus Group, were involved in the theft of $1 billion.
