What happenedTarter Krinsky & Drogin, a Manhattan law firm, reported that an unauthorized party accessed its servers between July 9 and September 9, 2025.
Who is affectedPatients of the firm's healthcare clients, plus patients of Park Dental in Roanoke, Virginia, and Heritage Pediatrics in San Antonio, Texas, who had separate breaches.
What to do
  1. 1Open any breach notification letter and read which of your details were exposed.
  2. 2Freeze your credit with the three major credit bureaus if your Social Security number was involved.
  3. 3Check bank, card and health insurance statements for charges or claims you do not recognize.
  4. 4Change passwords on any account named in the letter and turn on two-step sign-in.

A Manhattan law firm, Tarter Krinsky & Drogin, says an unauthorized person got into its servers and may have taken files holding the health information of 196,645 patients. Those patients were not the firm's own clients. They were patients of the healthcare organizations the firm works for. Letters are now going out to people who were affected.

What happened

The firm noticed suspicious activity on September 10, 2025. Outside investigators confirmed that someone had accessed some of its servers on and off between July 9 and September 9, 2025. During that time, certain files were accessed or acquired. The firm says it has now finished reviewing the affected files and has added security measures.

What was exposed

The details differ from person to person. The firm lists the following types of data that may have been involved:

  • Name, date of birth, Social Security number and driver's license number
  • Passport number and tax identification numbers
  • Bank account and payment card information
  • Usernames and passwords
  • Medical, health insurance and biometric data

Most people will not have every item on that list. Your letter should say which of your details were involved.

Two other breaches

The same report covers two smaller incidents at medical practices. Park Dental in Roanoke, Virginia, says an unauthorized person reached a workstation and an associate office email account between June 10 and July 22, 2026. About 12,000 people were affected. Exposed data may include contact details, x-rays, diagnoses, treatment plans, and insurance and billing information.

Heritage Pediatrics in San Antonio, Texas, found fraudulent emails being sent from one employee's email account in April 2026. That account held patient data. Letters went out on or around October 19, 2026. At the time, the practice had found no misuse of the data.

Who can relax

If no letter arrives, nothing in the report suggests you are affected. Notices are being mailed to the people whose files were involved. The report does not name the law firm's healthcare clients, so you cannot tell from the news alone whether your provider is one of them. The letter is the main way to find out.

What to do and what comes next

If you get a letter, do not toss it as junk mail. The steps in the alert box above explain what to do, starting with reading which of your details were exposed.

The report does not say whether any of the stolen data has been misused or who was behind the intrusion. Names, Social Security numbers and medical details can be used for fraud long after a breach, so keep an eye on your mail, your credit and your insurance statements in the months ahead.

The takeaway

If a breach letter arrives from a law firm or medical office, read it closely and act on the steps in the alert box.
