Story summary

Companies in Japan and South Korea recently faced major cyberattacks, resulting in the exposure of millions of customer records. This incident has heightened concerns about the potential use of artificial intelligence (AI) to enhance hacking efforts on an industrial scale. Just days before these attacks, Chinese and US AI models were reportedly used to steal hundreds of thousands of credit card details, described by analysts as one of the most severe abuses of AI for malicious purposes ever recorded. Corporate leaders, particularly in finance, view such threats from AI-driven cyberattacks as a critical danger to their businesses. Many companies are now urgently adopting AI technologies themselves, seeing them as the only effective countermeasure against these sophisticated attacks. Experts warn that some firms may already be behind in the race to protect against AI-powered hacking vulnerabilities.
