Suspected internal Involvement in Bank DKI Security Breach

Agus Haryoto Widodo, President Director of Bank DKI, addressed the media on Wednesday, April 16, 2025, revealing that the bank is investigating a potential hacking incident that led to a leakage of funds. The breach, which reportedly began on march 31, 2025, is suspected to involve a third-party actor working in collusion with individuals within Bank DKI’s management.

What is clear is that there is one third party that does not work as it should. They use high level access to enter the system.

Limited Impact on Customer Funds; Focus on System Recovery

Bank DKI has assured its customers that the fund leakage has not affected their accounts. according to Widodo, the compromised funds belong solely to the bank, with estimated losses not exceeding rp 100 billion. While the investigation continues, Bank DKI is prioritizing the restoration of full functionality to its digital services.

Currently, customer transactions are proceeding as normal through ATM networks and branch offices. However, the JakOne mobile application is experiencing limited functionality, notably concerning interbank transfers. The bank anticipates restoring full service, including interbank transfers, within the coming days.

The incident highlights the increasing threat of cyberattacks targeting financial institutions. According to a recent report by Cybersecurity ventures, cybercrime is predicted to cost the world $10.5 trillion annually by 2025, underscoring the critical need for robust cybersecurity measures within the banking sector.

Ongoing Forensic Examination and System Enhancements

Bank DKI has engaged a specialized institution to conduct a thorough forensic examination of its systems and implement necessary security enhancements. This includes identifying vulnerabilities exploited during the breach and fortifying the bank’s defenses against future attacks.

The bank is working diligently to restore full functionality to the JakOne Mobile application, with a target completion date of either this week or the following week. In the meantime, customers can continue to utilize other features of the application.
