Major banks across Asia are strengthening oversight of advanced artificial intelligence tools as next-generation cybersecurity models raise concerns that hackers could identify software vulnerabilities faster and launch broader attacks.
The shift follows growing attention around Anthropic’s new restricted-access cybersecurity model, Claude Mythos Preview, which the company says identified thousands of major vulnerabilities across leading operating systems and web browsers. While designed for defensive cybersecurity, the model has intensified concerns that frontier AI could also accelerate offensive cyber capabilities if misused.
Singapore’s largest bank, DBS, warned that such AI systems amplify cyber risk by increasing both the speed and scale of attacks. CEO Tan Su Shan said the technology could expand the “blast radius” of cyber threats, while also offering defensive advantages if deployed responsibly.
Other major regional lenders, including OCBC and UOB, said they are enforcing strict governance, internal guardrails, and rigorous testing before implementing advanced AI tools. Standard Chartered similarly acknowledged rising sophistication in cyber threats but described the trend as an escalation of long-standing risks rather than an entirely new category.
Regulators are also taking notice. Australia’s prudential watchdog recently warned that banks may not be adapting quickly enough to AI’s rapid evolution.
The broader concern is that frontier AI is reshaping cybersecurity into a dual-use battleground: banks can strengthen defenses faster, but malicious actors may also gain unprecedented speed in exploiting digital weaknesses. As financial institutions accelerate digital transformation, balancing AI innovation with security controls is becoming a critical operational priority.
