Dates come from the sources listed at the bottom of this page. Separate events are kept separate; where a date has not been disclosed, it says so.
What information was exposed?
The categories below come from Thomson Reuters C-Track's disclosure and the sources listed on this page. Each is labeled by what the evidence supports. Categories not mentioned in any source are not listed, even if they are common in similar breaches.
Name
Social Security number
Notice: some records could potentially contain Social Security numbers.
Government identification
Notice lists driver's license number among possible fields.
Date of birth
Health information
Medical information may have been in some records.
Insurance information
Health insurance information may have been in some records.
Other personal information
Confidential, redacted, or sealed court information may have been impacted for certain courts.
Why this information matters
The risks below are the ones associated with the categories of information involved in this breach. This describes how exposed information can be used in general. It does not state that any of this has happened with data from this incident.
Information from one breach can sometimes be combined with information from other breaches or public sources. A name and email address on their own are limited. Paired with a date of birth from one leak and an address from a people-search site, they become enough to answer a security question or make a scam call sound informed.
Whether the data from this breach has been sold, shared, or used is not known unless a source on this page says so. Where that is documented, it appears in the "What happened" section above.
If you were affected, consider doing these things now
Practical steps for this breach, in rough order of priority. None of these require buying anything. Monitoring services, including ours, are one option among several.
- 01If you were involved in court proceedings in an affected jurisdiction, review the official notice at ctracknotification.com and enroll in the complimentary monitoring if eligible.
- 02Call 1-833-918-5294 with engagement number B171847 if you have questions about whether you are affected.
- 03Watch for phishing that references court cases, C-Track, Thomson Reuters, or this incident.
- 04Because Social Security numbers and driver's license numbers may have been involved, consider a credit freeze with Equifax, Experian, and TransUnion.
- 05Check your free annual credit reports and watch for new accounts you did not open.
- 06If sealed or sensitive case information may involve you, ask the relevant court clerk what local guidance they have published.
- 07Consider a personal information monitoring service.
AI Protection
Monitoring, alerts, and recovery help for what comes after a breach.
A breach puts information you can't take back into circulation. AI Protection watches for it being misused, alerts you when something changes, and helps you recover if something goes wrong. It cannot undo the breach or retrieve data an attacker already holds.
How one breach can contribute to a larger exposure footprint
A possible risk pattern, not a description of this incident. Each step is something that can happen after a breach. Nothing here states that it has happened with data from this incident.
Illustrative pattern- Step 1
One breach
A single company's records are accessed without authorization.
- Step 2
Personal information is exposed
Some categories can be changed afterward. Others, like a name or date of birth, can't.
- Step 3
It may remain accessible
Copies of breached data can persist well beyond the original incident.
- Step 4
Sources can be combined
Fragments from different breaches and public sources may be assembled into a fuller profile.
- Step 5
More targeted attempts
A fuller profile can make fraud, impersonation, phishing, or social engineering attempts more convincing.
A breach is an event. Exposure can last longer.
A password can be reset and a card reissued. Some information can't be replaced, and that is the part that stays useful to someone attempting fraud later. This does not mean fraud will occur. It means the risk does not close when the news cycle does.
Involved in this breach and hard to change
None of the categories reported in this breach are in the hard-to-change group. Changeable items like passwords and account numbers should still be addressed.
