Jakarta (ANTARA) - Financial Services Authority (OJK) urged the national banking industry to remain highly vigilant against the growing threat of cyberattacks, while also advising the public, particularly bank customers, to stay calm regarding the issue.

Dian Ediana Rae, OJK's Chief Executive for Banking Supervision, stated in a written response to ANTARA in Jakarta on Monday that the regulator is treating the threat of cyberattacks with the utmost seriousness.

According to Rae, since November 6, 2026, OJK's banking information technology (IT) supervisors have been coordinating with the IT personnel of all banks to heighten their state of alert.

"I have also sent several letters to bank boards of directors regarding cybersecurity. Last week, I reminded bank management to remain on high alert due to the recent rise in cyberattacks and to implement the preventive measures detailed in my correspondence," Rae said.

Rae explained that the OJK has requested that banks take specific technical actions, such as monitoring significant transactions and temporarily halting anomalous transactions pending further clarification.

Regarding digital resilience, he added that banks are already required to conduct penetration testing, cyberattack simulations, and IT audits.

He emphasized that IT security is a highly dynamic field, evolving in tandem with rapid technological advancements.

Consequently, banks must be responsive in anticipating technological developments, including the adoption of technologies designed to prevent cyberattacks.

Rae noted that the OJK and Bank Indonesia (BI) have activated a Cyber Incident Response Team (TTIS) to prepare for potential cyber incidents.

Furthermore, the OJK encourages the public to remain calm and continue their banking transactions as usual, while ensuring they follow the account security protocols prescribed by their respective banks.

Rae also advised the public to access information regarding banks only through official channels and to disregard speculative reports or information that lacks a reliable source.

Notably, concerns regarding cybersecurity, particularly within the banking sector, have become a frequent topic of discussion among the public on social media.

According to the FortiGuard Labs live threat map dashboard, accessed this Monday at 15:02 WIB, 1.9 million cyberattacks were successfully blocked over the last 24 hours. The dashboard indicates a rate of 22 attacks per second.

These observations show that the banking, finance, and insurance sectors are the primary targets for cyberattacks, accounting for 999,000 incidents over the past 24 hours.

The technology sector follows with 421,000 attacks, while the government sector ranks next with 101,000.
