On February 1, 2025, the Indonesian water utility PT Tirta Raharja Perkasa appeared on the leak site of the funksec ransomware group. The company, which supplies clean drinking water to remote communities, had internal files exfiltrated during a ransomware attack. While the exact number of people whose personal information may have been exposed remains unknown, anyone who has interacted with the utility — as a customer, employee, vendor, or family member — may now find their data circulating in criminal circles.
Already exposed?
You can’t unleak data. You can take away what it’s worth.

Reported Details of the Breach
Public reporting indicates that funksec listed tirtaraharja.co.id on its dark-web leak portal after the company apparently declined to pay a ransom demand. The data consists of internal files stolen before encryption took place. No precise count of records has been published, and the precise types of information inside those files have not been independently verified by third parties. The listing appeared on a Tor onion address tracked by ransomware.live, a site that monitors ransomware activity.
Available reporting describes the incident as a classic ransomware double-extortion case: the attackers first deployed malware to encrypt systems, then threatened to publish stolen data unless payment was made. As of the publication date, the files remain accessible on the leak site.
Why This Matters for You and Your Family
Even when a breach hits what seems like a local utility, the consequences reach ordinary households. If your address, phone number, national ID details, or payment records were inside those internal files, criminals can use them for identity theft, targeted scams, or to pressure you into paying fake “fines” related to water-service accounts. Families in served communities often share the same billing address or phone number, which means one exposed record can affect parents, children, and grandparents at the same address.
