South Korea reports 2,383 cybersecurity breaches in 2025 amid AI-powered attack surge

The report describes a sharp increase in cybersecurity breaches and says the threat environment is being reshaped by AI-enabled social engineering. It highlights deepfake audio and video as emerging tools used to impersonate executives, colleagues, and trusted partners in so-called trust-based communication channels. The report also notes that South Korean officials expect these tactics to become more prevalent in 2026. The source is a trend report rather than a single new incident, but it is a newly released government disclosure about recent breaches.
