JAKARTA, June 4 (Xinhua) -- Indonesia's Financial Services Authority (OJK) on Thursday called on financial institutions to strengthen digital transaction security as cybercrime threats, including ransomware attacks and artificial intelligence (AI)-enabled fraud, continue to intensify.

The authority said robust cybersecurity measures are increasingly important as digital payment usage expands, stressing that financial institutions must improve resilience against fraud to maintain public trust and business sustainability.

"Industry readiness in strengthening digital transaction security is now very crucial," OJK Consumer Legal Protection Director Tri Herdianto said.

According to Bank Indonesia, digital payment transactions reached 14.82 billion in the first quarter of 2026, up 37.69 percent from the same period a year earlier.

However, the rapid growth of digital finance has been accompanied by rising cyber risks, with criminals increasingly using AI to launch more sophisticated and harder-to-detect attacks.

Indonesia's National Cyber and Crypto Agency recorded 5.2 billion internet traffic incidents with potential cyberattack risks in 2025, of which 94 percent involved high-risk malware that could potentially develop into ransomware attacks.

The OJK said stronger collaboration, enhanced fraud detection systems and shared security infrastructure are essential to building a safer and more resilient digital financial ecosystem. ■
