The Financial Services Authority (OJK) and the Indonesia Stock Exchange (BEI) have issued a statement regarding alleged illegal access and fraud incidents at Mirae Asset Sekuritas. According to information gathered by Katadata, a client claims to have incurred a substantial loss of Rp 71 billion from these incidents.
Inarno Djajadi, OJK’s Chief Executive of Capital Market, Derivative Finance, and Carbon Exchange Supervision, confirmed that the authority is actively investigating the case. He noted that, based on initial reports received by OJK, the matter does not appear to be connected to the client’s Customer Fund Account (RDN).
Djajadi elaborated that the Mirae Asset client reported their account had been breached, with blue-chip stocks allegedly sold without their knowledge. Subsequently, the funds from these unauthorized sales were reportedly diverted to purchase non-blue-chip stocks. “These transactions, involving the acquisition of non-blue-chip stocks without the client’s consent, are currently under our thorough investigation,” Inarno stated during a working meeting with OJK and BEI at the Senayan Parliament Complex in Jakarta on Wednesday, December 3.
Furthermore, Inarno emphasized OJK and BEI’s commitment to bolstering the cybersecurity systems of exchange members (AB) to prevent similar RDN breaches in the future. He affirmed, “By 2026, we are fully concentrating our efforts on enhancing cybersecurity across the entire capital market ecosystem.”
Meanwhile, Kristian Manullang, BEI’s Director of Transaction Supervision and Compliance, confirmed that the exchange has received reports concerning the misuse of client assets within a client’s securities account from Mirae Asset Sekuritas. He noted that BEI and Self-Regulatory Organizations (SROs) have already conducted comprehensive analyses of the case, examining both transaction specifics and securities mutations.
“We are coordinating closely with SROs and OJK. For every case we receive, we promptly initiate an analytical review and examination,” Kristian explained in his statement on Wednesday, December 3.
Beyond this specific incident, Kristian highlighted that BEI and OJK consistently provide guidance to exchange members regarding IT governance. This proactive approach ensures that exchange members conduct rigorous testing of their IT systems’ reliability, perform penetration tests, and receive support to strengthen their overall IT security.
Mirae Asset’s Explanation
Mirae Asset Sekuritas has also addressed the report filed by one of its clients with the National Police Criminal Investigation Department (Bareskrim) concerning alleged illegal access and fraud. According to information gathered by Katadata, the client asserted a significant financial loss, totaling Rp 71 billion.
The management of Mirae Asset Sekuritas stated its awareness of the circulating client report. Mirae Asset indicated that it is currently conducting an internal investigation and coordinating with OJK, Self-Regulatory Organizations (SROs), and the Financial Transaction Reports and Analysis Centre (PPATK).
“Our aim is to ensure that the investigation and resolution of this case are conducted with the utmost diligence and in full compliance with all applicable regulations,” the Mirae Asset Sekuritas management declared in an official statement on Monday, December 1.
From its preliminary examination, the company uncovered indications that the client might have shared their password and access credentials for their investment account with other parties. Such an action, Mirae Asset emphasized, constitutes a violation of security guidelines and inherently poses serious risks to account integrity.
However, the management clarified that these initial findings are still being thoroughly investigated. Mirae Asset affirmed that it reserves the right to pursue legal action should the investigation reveal any misuse, false reporting, or actions detrimental to the company’s reputation.
“We assure our clients that the company’s platform, systems, and operations remain secure and are functioning normally, in adherence to industry standards and applicable regulations,” the company added.
The company also urged all clients to meticulously safeguard the confidentiality of their account information, including passwords, PINs, and OTP codes, advising against sharing them with anyone to prevent unauthorized access. Separately, a client identified as Irman reportedly filed a complaint against Mirae Asset Sekuritas President Director Tae Yong Shim, Director Tomi Taufan, and Director Arishandi, alleging fraud and illegal access. This report was officially registered with the number LP/B/583/XI/2025/SPKT/BARESKRIM Polri on Friday, November 28.
Summary
The Financial Services Authority (OJK) and the Indonesia Stock Exchange (BEI) are investigating alleged illegal access and fraud incidents at Mirae Asset Sekuritas, following a client’s claim of a Rp 71 billion loss.
