Banks and other financial companies are strengthening their cybersecurity by deploying artificial intelligence (AI)-powered security tools as the emergence of autonomous AI agents raises concerns over sophisticated cyberthreats, industry officials said Wednesday.

Officials say that the financial sector is entering an "AI versus AI" era, where AI is increasingly being used not only to launch cyberattacks but also to detect vulnerabilities in advance and strengthen defenses.

Major financial groups and their affiliated banks have recently accelerated the adoption of AI-based cybersecurity tools.

Woori Financial Group launched its AI-powered penetration testing platform Xint in May.
