Bank Data Breach Rumours: Cybersecurity Experts Respond
Generally, Indonesia’s banking sector has one of the strongest security systems, especially in large banks. This was stated by digital expert Syahraki Syahrir in response to recent data breach rumours implicating several banking institutions, which have caused public concern.
Syahraki, also CEO of Veda Praxis, a digital and cybersecurity consultancy firm, explained that the banking sector is the most mature industry in managing information technology (IT) security. He noted that Indonesian regulators have long enforced strict rules on banking information system security.
According to the man commonly known as Raki, financial industry oversight is conducted through multiple layers by agencies such as the Financial Services Authority (OJK), Bank Indonesia, the National Cyber and Crypto Agency (BSSN), and the Ministry of Communication and Digital Affairs. “All these regulators continuously enhance security standards for banks and educate the public and industry players,” he said on Saturday, 23 May 2026.
Regarding data leak rumours on the dark web, the public is advised not to panic excessively. Raki explained that the dark web is an unindexed part of the internet often used for unrestricted activities, including spreading unverified and illegal data.
In today’s digital ecosystem, systems are interconnected with various parties, including technology providers, infrastructure services, and other partners, he added. Data circulating online may not necessarily originate from core banking systems.
“If the dark web data is genuine, we must trace its source. It could come from third parties linked to banking services, so don’t immediately assume the banks are weak. However, when banks are implicated, public concern spikes because people’s money is involved,” he said.
Earlier, as reported by Antara, OJK Commissioner Chairperson Friderica Widyasari Dewi stated that while banks have layered security systems and comply with personal data protection regulations, crimes can still occur if customers are careless with their personal information.
“Even with robust security measures and regulatory compliance, financial crimes can happen if customers are not vigilant or neglect to safeguard their personal data,” she said.
Known as Kiki, she added that cybercrime risks in the financial sector are rising due to increasingly sophisticated criminals, while many citizens lack adequate digital and financial literacy.
In response, Raki said the rise in cybercrime is a consequence of more complex digital technology use in daily life. He urged the public to remain vigilant online, such as not sharing personal information via phone calls, instant messages, or other digital media—even with those claiming to be from banks.
“Never share passwords, PINs, or OTPs with anyone. If someone requests sensitive data via phone or digital messages, be immediately cautious,” he said.
Most importantly, Raki stressed the need to cultivate a culture of caution in daily digital activities. He advised verifying information or requests through digital channels before trusting them. “In today’s era, we must be extra careful. Do not easily believe phone calls, messages, or links claiming to be from any entity, including banks. If in doubt, conduct transactions and communications through official apps or visit branch offices directly,” he said.
