North Korean hacking group Kimsuky has experienced a significant data breach after two ethical hackers, known as 'Saber' and 'cyb0rg,' leaked 8.9GB of the group's data, exposing their tools and stolen information. The hackers criticized Kimsuky for its politically motivated cyber activities and claimed their actions were aimed at revealing the group's unethical practices. This breach may complicate Kimsuky's operations and disrupt their ongoing campaigns, although its long-term impact remains uncertain.
