Bni.co.id bank of indonesia free data. Listed by Triple X Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
BNI has been listed by the Triple X Ransomware Group, which claims to have exfiltrated internal files from the organisation. The incident was disclosed on 13 June 2026; affected individuals should check whether their data is involved and take any recommended protective steps.
On June 13, 2026, the Triple X Ransomware Group listed BNI on its leak site and claimed to have obtained internal files from bni.co.id. The group stated that the material includes customer information dated 2024 to 2026 and described the total volume as approximately 2 TB, with an initial 100 GB portion offered for free download. The number of individuals affected remains unknown, and no independent confirmation of the data’s contents or the circumstances of its acquisition has been made public.
The listing is one of many similar claims made by ransomware operators that combine file exfiltration with public pressure tactics. Such incidents continue to affect financial-sector organisations that process large volumes of personal and contractual records.
Inside the incident
The only public record of the event is the June 13, 2026 listing on the group’s site. The post asserts that internal files were removed during a ransomware operation and names customer contracts, passports and ID cards among the material. Sample images are referenced but not independently verified. The group provided a download link and password for an initial segment of roughly 100 GB and indicated that additional portions would be released or sold. No statement from BNI or Indonesian regulatory authorities has been issued in connection with the listing, and details such as the precise method of access or the timeline of any encryption activity are not disclosed.
Who is Triple X?
Triple X is a ransomware group that maintains a public leak site to advertise data it claims to have taken from targeted organisations. Like other actors in this category, the group typically seeks payment in exchange for withholding further publication or for providing a decryption key. Its listings often include sample files and volume estimates to demonstrate possession of material. Public reporting on the group’s prior activity shows repeated use of this extortion model against entities in multiple sectors, though specific claims regarding any single victim require separate verification.
About BNI
BNI operates as a major commercial bank in Indonesia. Institutions of this type routinely collect and store customer identification documents, account agreements, transaction records and related personal data in order to comply with know-your-customer and anti-money-laundering requirements. A successful intrusion that results in the removal of such records can expose both the bank and its customers to downstream misuse of the information.
What data was at risk
The listing describes internal files containing customer information from 2024 to 2026, including contracts, passports and ID cards, with a claimed total size of 2 TB. No official statement has confirmed these descriptions or provided an inventory of the files. Organisations in the banking sector commonly hold additional categories of data such as account numbers, addresses and financial histories; whether any of those categories are present in the claimed material is not confirmed.
Why it matters
Passports and national ID documents can be used for identity fraud or account takeover attempts. Contractual records may reveal details of financial relationships that could be exploited for targeted scams. For the organisation, the incident raises questions about access controls and data-handling practices, even though the precise security posture at the time of the claimed exfiltration is not public. Regulatory obligations around breach notification and customer protection may also apply once the facts are established.
Were you affected?
Individuals who hold accounts or have conducted business with BNI should monitor their financial statements and credit reports for unusual activity. Changing passwords for any linked online services and enabling multi-factor authentication where available are standard first steps. Readers may also submit their email address to a free exposure-checking service to determine whether their information appears in known breach datasets.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
