Indonesia Power Listed by RansomHouse Ransomware Group

On March 20, 2023, Indonesia Power, the state-owned electricity generator that supplies most of Java and Bali, appeared on the RansomHouse leak site. The listing states that internal files were exfiltrated during a ransomware attack. The company has not published a public breach notification, and the exact number of people whose data may be affected remains unknown.

Reported Details from the Listing

The RansomHouse portal lists Indonesia Power as a victim and claims the attackers extracted internal files. No sample data has been published on the site, and the leak page does not specify what categories of information were taken or how many records are involved. The disclosure indicates the incident occurred before the March 20 publication date, but the precise breach window is not stated. Indonesia Power operates 127 power plants with a combined capacity of 8,888 MW and is headquartered in South Jakarta; the listing makes clear the target was this critical national infrastructure operator.

Why This Matters for You and Your Family

When a utility of this scale loses control of internal files, the consequences reach far beyond corporate networks. Employee records, contractor details, customer billing information, and vendor contracts are the kinds of documents typically stored on corporate file servers. If any of those files contained personal data linked to you — an electricity account, an employment record, or a family member’s service address — that information may now be in the hands of criminals. Internal files exfiltrated in ransomware incidents frequently include spreadsheets with names, addresses, national ID numbers, and contact details. Even without an exact victim count, the exposure creates immediate risk for anyone whose data touched Indonesia Power’s systems.

The Doxxing and Identity-Chain Implications

Stolen internal documents rarely stay isolated. Attackers map relationships between corporate emails, phone numbers, employee names, and external accounts. A single leaked work address or spouse’s name can link your gaming username, social-media handle, and children’s school records into one continuous identity chain. Credential leaks of this type routinely cascade into account takeovers on personal email, banking portals, and online gaming services. DoxxScan by GalaxyWarden continuously monitors across 13.1 billion+ breach records and more than 100 platforms, using AI-powered identity-chain mapping to surface these connections before they are exploited. The service also covers your entire household, including children’s gaming accounts that often become the next link in the extortion chain.

RansomHouse’s Publicly Known Track Record

Public reporting attributes the first RansomHouse activity to late 2021. The group has since listed dozens of organizations across manufacturing, healthcare, education, and critical infrastructure. Their typical playbook begins with initial access through compromised credentials or vulnerable remote desktop services, followed by claimed exfiltration of sensitive files before encryption. RansomHouse then posts a sample of stolen data and demands payment to prevent full publication. They have repeatedly targeted energy and utility companies, demonstrating both the capability and the intent to pressure large infrastructure operators. The exact tactics used against Indonesia Power have not been disclosed, but the group’s established pattern matches the listing that appeared on their leak site.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, handles, and real-world identity, with cleanup handled by the service.
• Enable continuous DoxxScan monitoring so the next time a breach exposes your data it is detected within hours rather than months.
• Rotate any password you used at Indonesia Power or related vendor portals and replace it with a unique passphrase; enable 2FA through an authenticator app on every account where the same credentials were reused.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts commonly chained to the same residential address.
• Let the remediation specialists manage takedown requests across data-broker sites and extortion portals on your behalf.

The Indonesia Power listing is a reminder that even national infrastructure breaches quickly become personal when names and addresses escape corporate control. Acting quickly on the exposed data chain can limit how far attackers push the information. Start your DoxxScan trial today to gain both visibility into existing leaks and specialist support that keeps your family’s digital footprint from growing.
