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

P.M. Medical Billing was listed on Alphv's leak site. Alphv claims to have stolen internal data. This is the group's claim, not a confirmed finding.

PM Medical Billing was hacking A company with multiple vulnerabilities in its network allo Listed by alphv Ransomware Group

On May 17, 2023, medical billing provider P.M. Medical Billing Corp of Oyster Bay, New York, appeared on the leak site of the Alphv ransomware group. The listing states that internal files were exfiltrated following a ransomware attack that exploited multiple vulnerabilities in the company’s network. The disclosure does not quantify how many patient records or individuals may be affected, nor does it list the specific types of documents stolen.

Details from the Leak-Site Listing

The Alphv leak page, still accessible at the time of the initial disclosure, claims that P.M. Medical Billing suffered a breach after attackers gained access through unpatched vulnerabilities. The posting asserts that a substantial volume of internal files was taken before encryption occurred. No sample data is shown on the public page, and the exact number of records exposed remains unknown. The company, which has specialized for over two decades in ophthalmology and optometry billing, maintains headquarters at 111 South Street, Suite 6, Oyster Bay, New York. Its website and public contact details were also referenced in the listing.

May 17, 2023 marks the first confirmed public disclosure via the ransomware operator’s dedicated leak portal. The notification does not indicate whether P.M. Medical Billing has paid any ransom or engaged with the threat actors.

Why This Matters for You and Your Family

When a medical billing company is breached, the information at risk often includes names, dates of birth, Social Security numbers, insurance details, diagnosis codes, and billing records for thousands of patients. Even though the exact data set is not detailed in the Alphv listing, the nature of the business means sensitive protected health information tied to eye-care practices across the country could be in attackers’ hands. For you or your family members who have visited an ophthalmologist or optometrist serviced by this firm, that exposure creates long-term privacy and financial risks, including fraudulent insurance claims, tax fraud, or impersonation using legitimate medical histories.

Medical data is particularly sticky once leaked because it combines identity details with health information that many people assume remains private. A single breach like this can feed identity thieves for years.

The Doxxing and Identity-Chain Risks

Exfiltrated internal files frequently contain spreadsheets that link patient names to addresses, phone numbers, email accounts, and sometimes employer information. Threat actors and downstream data brokers can combine these records with other breaches to build detailed profiles. A seemingly harmless ophthalmology billing record can become the missing link that connects an anonymous username on one platform to a real-world identity on another. This chaining effect turns isolated leaks into full doxxing packages that expose home addresses, family relationships, and even children’s names when guardian information appears in billing files.

Credential leaks that surface in the same datasets can also cascade into account takeovers. Passwords or email addresses reused from a medical provider can give attackers entry to personal email, banking, or gaming accounts belonging to you or your children.

Alphv’s Known Track Record

Public reporting attributes the Alphv group, also known as BlackCat, with emerging in late 2021 after the shutdown of the REvil ransomware operation. The gang has targeted healthcare, education, manufacturing, and professional services organizations. Notable prior victims include large hospital systems and technology providers where patient or employee data was later posted for extortion. Their typical playbook involves initial access through vulnerable remote desktop services or unpatched web applications, followed by lateral movement, data exfiltration, and then dual extortion: threatening both encryption and public leak of stolen files. Alphv frequently sets short deadlines for payment before releasing samples or full datasets on their Tor-based leak site.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup handled by the service.
  • Rotate any password you used at pmbiller.com or related ophthalmology providers anywhere it has been reused, and switch to 2FA using an authenticator app rather than SMS.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure of your information is caught in hours, not months.
  • Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often become targets when credential leaks chain back to the same address or parent email.
  • Let remediation specialists perform hands-on takedown requests across data brokers and leak sites on your behalf while you focus on securing accounts.

The incident underscores that even specialized medical billing firms remain high-value targets for ransomware operators who prioritize data volume over ransom size. Staying ahead requires more than reactive checks; it demands ongoing visibility into how your personal information travels across the internet. DoxxScan by GalaxyWarden delivers that visibility through 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-based attacks.

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.
