chcm.us Listed by lockbit3 Ransomware Group

On September 26, 2024, the LockBit3 ransomware group listed College Hospital Costa Mesa (chcm.us) on its leak site, announcing that it had exfiltrated internal files during a ransomware attack on the Southern California psychiatric and medical facility.

Details from the Leak-Site Posting

The LockBit3 listing states that College Hospital Costa Mesa, which provides psychiatric care, medical/surgical services, and outpatient telehealth, had its internal files taken. The disclosure does not specify the number of records affected, the exact data types beyond “internal files,” or any ransom demand. It simply states that data was exfiltrated and is now hosted on the group’s onion site for anyone to review. The posting follows the group’s standard format: a brief company description followed by proof files and a countdown clock. No patient names, financial records, or specific document categories are detailed in the initial listing itself.

Why This Matters for You and Your Family

If you or a family member has ever received care at College Hospital Costa Mesa, your protected health information may now sit in an attacker-controlled archive. Psychiatric records are especially sensitive because they can include diagnoses, treatment notes, medication histories, and family dynamics that many people prefer to keep private. Even if the leak site does not yet list every file, the mere confirmation that internal files were taken creates long-term exposure. Once data leaves a hospital’s control, it can surface on dark-web markets, extortion forums, or public paste sites months or years later.

The Doxxing and Identity-Chain Risks

Health-care breaches rarely stop at clinical notes. Internal files often contain names, dates of birth, Social Security numbers, addresses, insurance details, and phone numbers that tie directly to your real-world identity. Attackers and opportunistic data brokers can combine these with credentials stolen from other breaches to build a complete profile. A single leaked email or phone number from this incident can unlock gaming accounts, social-media handles, and financial portals. For families, the risk extends to children: a parent’s leaked medical record can expose a dependent’s information and lead to takeovers of their Roblox, Fortnite, or Discord accounts that later become vectors for further doxxing.

LockBit3’s Known Track Record

Public reporting attributes LockBit3 as the current iteration of the LockBit ransomware operation, which first appeared in 2019 and rebranded after law-enforcement actions against earlier versions. The group has targeted hospitals, schools, manufacturers, and local governments worldwide. Its typical playbook involves initial access through compromised remote desktop credentials or vulnerable web applications, followed by rapid lateral movement, data exfiltration, and then dual extortion: demanding payment to prevent file encryption and a second payment to stop data leaks. When victims refuse to pay, LockBit3 publishes samples and maintains a public countdown, exactly as seen with College Hospital Costa Mesa.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, including any records that may have surfaced from this breach.
• Rotate any password you used at College Hospital Costa Mesa or its patient portal anywhere else it is reused, and switch to 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure that touches you or your family is caught in hours, not months.
• Cover the entire household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often chain back to the same leaked contact details.
• Let remediation specialists handle data-broker takedown requests and follow-up monitoring for you instead of attempting manual removal across dozens of sites.
