If you are a client of PT. Bank Perekonomian Rakyat Bintan, here’s what is being claimed, and what it would mean for you.

PT. Bank Perekonomian Rakyat Bintan is an Indonesian rural bank, known as a Bank Perkreditan Rakyat or BPR, operating in the Bintan regency of Riau Islands province, Indonesia. It provides basic financial services including savings, deposits, and credit facilities primarily to local communities, small businesses, and micro-enterprises. As a rural bank, it operates under supervision of the Indonesian Financial Services Authority, OJK, serving the local economy.

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

This means that if the claim is accurate, information you provided when opening or maintaining an account at the bank could be in the hands of people who have every incentive to use or sell it. Because this is an unverified extortion listing rather than a claimed breach notification, the first thing to understand is how much uncertainty remains.

What a Ransomware Leak-Site Listing Actually Establishes

Ransomware crews frequently publish the names of banks and financial institutions on dark-web leak sites as part of their extortion playbook. The listing itself is marketing material designed to pressure the target into paying. It does not constitute independent proof that a breach occurred, that data was successfully exfiltrated, or that any specific records remain usable.

Many such listings turn out to be recycled from older incidents, contain data scraped from public sources, or are posted without having obtained anything beyond initial network access. Some groups name organisations simply to damage their reputation even when negotiations fail or no meaningful theft took place. Without confirmation from the bank, a regulator, or forensic evidence shared publicly, the listing remains an accusation, not a verified event. The record provides no count of affected individuals and does not describe any specific categories of information taken.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
