Seoul, Jan 27 (IANS) The number of cybersecurity breaches reported to authorities rose 26 per cent from a year earlier in 2025, a government report here showed on Tuesday, as hackers continue to develop their attack tactics based on artificial intelligence (AI) technologies.

The total number of cybersecurity breaches came to 2,383 in 2025, compared with 1,887 tallied a year earlier, according to the report by the Ministry of Science and ICT, reports Yonhap news agency.

Of the cases, server intrusions accounted for 44.2 per cent, followed by distributed denial-of-service (DDoS) attacks at 24.7 per cent.
