high severity December 15, 2023 · 3 min read Unverified claim — what this is

Water For People Listed by medusa Ransomware Group

If you are a customer of Water For People, here’s what is being claimed, and what it would mean for you.

Water For People is a global nonprofit dedicated to promoting the development of high-quality drinking water and sanitation services, accessible to all, and sustained by strong communities, businesses and governments. The main office of the company is located at 100 E Tennessee Ave, Denver, Colorado, 80209, United States.

— from Medusa’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.
Water For People Listed by medusa Ransomware Group

On December 15, 2023, the nonprofit organization Water For People appeared on the leak site operated by the Medusa ransomware group. The listing states that internal files were exfiltrated during a ransomware attack on the Denver-based humanitarian group that works to deliver clean drinking water and sanitation services worldwide. The number of people whose information was taken remains unknown, and the precise contents of the stolen files have not been detailed by the threat actors.

Details in the Medusa Listing

The primary disclosure on the Medusa leak site states that Water For People suffered a ransomware intrusion and that attackers successfully removed internal files before encryption. No specific volume of records, list of data types, or ransom amount is published in the entry. The organization’s headquarters address in Denver, Colorado, is publicly known and appears in the listing alongside the claim of successful data theft. As of the publication date, the files themselves had not been broadly released to the public, which is consistent with Medusa’s typical staged extortion approach.

Why This Matters for You and Your Family

When a nonprofit like Water For People is breached, the people whose personal information appears in its internal files face direct risk. Internal files often contain donor records, employee payroll data, vendor contracts, or beneficiary information from water and sanitation projects in multiple countries. If your name, address, email, phone number, or financial details were stored in those systems, the breach means criminals now hold data that can be used for identity theft, phishing, or targeted scams. Even though Water For People focuses on global development work, the exposure still reaches ordinary individuals and families who interacted with the organization as donors, volunteers, or program participants.

Doxxing and Identity-Chain Risks

Stolen internal files frequently create long-term doxxing chains. A single email or phone number taken from a nonprofit database can be correlated with gaming accounts, social-media handles, and family-member records. Attackers then build a complete profile that links your online activity to your real-world identity and home address. This is especially dangerous for families because children’s information or gaming usernames sometimes appear in the same shared spreadsheets or contact lists. Once the chain begins, one breach can lead to account takeovers across unrelated services, harassment, or fraudulent loan applications in your name.

Medusa’s Known Track Record

Public reporting attributes the Medusa ransomware group’s emergence to mid-2021. The actors have since targeted organizations across healthcare, education, manufacturing, and nonprofit sectors. Their playbook typically involves initial access through compromised remote-desktop credentials or phishing, followed by exfiltration of sensitive files before deploying encryption. Medusa then posts samples or full datasets on their leak site if the victim does not pay, using a double-extortion model that combines ransomware demands with public shaming. The group’s leak site remains active and continues to list new victims on a regular basis.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup of Warden to remove what you can.
  • Rotate any password you used with Water For People or any related online account, and switch to 2FA through an authenticator app instead of text messages.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours rather than months.
  • Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts that often chain back to the same address or parent email.
  • Let remediation specialists handle takedown requests for any exposed personal records found on data-broker or extortion sites.

The incident shows that even mission-driven organizations can become entry points for identity compromise that reaches ordinary households. Starting with a clear picture of your current exposure is the most practical step you can take today. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, and hands-on remediation by specialists, with household coverage that includes children’s gaming accounts vulnerable to credential-stuffing attacks that follow breaches like this one.

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.
