Ex-fantester linked to 90 South Korean breaches South Korean police have identified seven suspects in a cybercrime operation that hit more than 90 organizations and allegedly stole 8.2 million data records. In most cases, the group used the ARTEX AI experimental framework; 38 incidents also involved ransom demands totaling 360 million won. The alleged ringleader had prior internship experience and worked at a cyber security company from 2019 to 2022. The case highlights how autonomous offensive tools can increase hacking activity across engaged civilian targets, including hospitals, schools, corporations and small businesses. The investigators claim that the suspect switched from conventional tools to artificial intelligence services in late August 2026, indicating a measurable increase in rate and reach rather than a change in target.
