Dameron Hospital Listed by ransomhouse Ransomware Group

If you were named in this filing, here’s what is being claimed, and what it would mean for you.

Dameron Hospital provides acute and tertiary level care. This hospital provides cardio, emergency, pharmacy, physical therapy, and a variety of other individual and family health care services. Dameron is headquartered in Stockton, California.

— from Ransomhouse’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.
Dameron Hospital Listed by ransomhouse Ransomware Group

On December 5, 2023, Dameron Hospital in Stockton, California, appeared on the leak site operated by the ransomhouse ransomware group. The listing states that internal files were exfiltrated during a ransomware attack on the acute-care and tertiary medical provider. The disclosure does not specify the number of individuals affected or list exact data types beyond claiming that internal files were taken.

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 582 companies.

Details from the Leak-Site Listing

The ransomhouse page, accessible via the .onion link hosted on ransomware.live, identifies Dameron Hospital as a victim and claims successful data exfiltration. It does not publish samples or provide a full inventory of what was taken. The hospital itself has not yet issued a public notification quantifying impacted records or describing the precise scope of patient or employee information involved. Public reporting on similar ransomhouse listings indicates that when full data dumps are later released, they often contain spreadsheets, databases, and scanned documents pulled from compromised networks.

Dameron Hospital offers cardio, emergency, pharmacy, physical therapy, and family health services across its Stockton facilities. Any records stored on its internal systems could include names, addresses, dates of birth, Social Security numbers, medical histories, insurance details, and treatment records for thousands of patients and staff.

Why This Matters for You and Your Family

If you or any member of your family has received care at Dameron Hospital, your personal and medical information may now sit in an attacker-controlled archive. Medical data is especially sensitive because it combines identity details with protected health information that retains value to identity thieves for years. Even when the leak-site listing does not detail exact record counts, the exposure of internal files from a regional hospital typically affects current and former patients along with employees. This creates long-term risks of fraud, insurance abuse, and targeted phishing that can follow you or your children for a decade or more.

The breach also underscores how everyday healthcare providers remain prime targets. When a hospital’s network is breached, the consequences reach far beyond the facility’s walls and land directly on the families who trusted it with their most private information.

The Doxxing and Identity-Chain Implications

Stolen internal files frequently contain spreadsheets that link patient names to addresses, phone numbers, email accounts, and sometimes employer information. Attackers and subsequent data brokers can chain these records with usernames found in other breaches, creating detailed profiles that tie your real identity to online handles. Those profiles are then sold or used to launch account takeover attempts against email, banking, or social-media accounts. Because medical breaches often include family members listed as emergency contacts or dependents, one person’s exposure can pull an entire household into the chain. Children’s records are especially troubling: a stolen date of birth and parent address can seed synthetic identities or enable doxxing that surfaces in gaming communities where kids use the same email or phone number.

RansomHouse’s Publicly Known Track Record

Public reporting attributes the emergence of RansomHouse to mid-2022. The group has since listed dozens of organizations across healthcare, education, and manufacturing sectors. Notable prior victims include other U.S. hospitals and regional medical centers, though exact details remain limited because RansomHouse rarely publishes full proof packages immediately. Their typical playbook involves initial access through phishing or exploited remote-desktop services, followed by quiet exfiltration of documents before encryption. Rather than always deploying ransomware, they often rely on extortion alone—threatening to publish stolen files unless payment is made. The group maintains a leak site that posts victim names and countdown timers, a pattern consistent with the December 5, 2023, listing for Dameron Hospital.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity drawn from this and earlier breaches.
  • Rotate any password you used at Dameron Hospital’s patient portal or related services anywhere else it is reused, and switch to 2FA through an authenticator app instead of SMS.
  • 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, which often chain back to the same addresses and emails stolen in healthcare incidents.
  • Let remediation specialists handle takedown requests for any exposed personal documents or broker listings that surface from this claimed breach.

The incident at Dameron Hospital illustrates how a single healthcare breach can quietly feed long-term identity abuse and doxxing campaigns. Staying ahead requires more than reactive checks; it demands ongoing visibility and expert help. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts.

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.
