Cybersecurity firm CrowdStrike says a suspect based in China used AI tools while hacking South Korean banks. The finding suggests attackers are folding artificial intelligence into their routine methods rather than treating it as a novelty. Such tools let criminal crews craft convincing phishing lures and churn out malware variants far faster than hand-written code. Banks make prime targets because they hold customer data and payment flows in one place. South Korea's financial sector has been hit by intrusions before, and regulators there have pushed institutions to harden their defences. Attribution in hacking cases is rarely clean, and pinning the attack on a China-based suspect could stir diplomatic friction alongside the technical response. The report does not name which banks were struck or what was taken.
