Millions of students caught in California data breach
You send your child to school expecting teachers to protect their education. You probably don't think much about what happens to their personal information after they take a standardized test. But a massive data breach in California is raising some uncomfortable questions about who has access to student records and how safely that information is stored.
Hackers accessed and copied sensitive records belonging to millions of current and former California public school students. The stolen information includes home addresses, birth dates and even details about disabilities. And here's something families need to know. You could live thousands of miles from California today and still be caught up in this breach if you or your child previously attended a public school there.

ORACLE HEALTH DATA BREACH EXPOSES NEARLY 20 MILLION PATIENTS
The breach involves Educational Testing Service (ETS), a nonprofit organization that works with the California Department of Education. ETS helps administer statewide student assessments and maintains information connected to those tests. According to state officials, someone gained unauthorized access to an ETS-operated secure file transfer site. Investigators determined that the attacker used a compromised login credential to enter the system. The intruder then copied files containing student information at various times between May 22 and Sept. 18, 2026.
ETS discovered the suspicious activity on Sept. 25. The company disabled the affected account and took the file transfer site offline. It also brought in outside cybersecurity specialists to investigate. The company says it has since built a replacement system with stronger security controls. So far, ETS reports finding no evidence that the stolen information has been made publicly available. However, investigators have confirmed that someone accessed and copied the records.
The California student data breach involved far more than test scores. Depending on the student, the compromised files may contain information that could help someone identify a child or learn personal details about their family circumstances.
The exposed records may include:
Some records also identified whether a student qualified for programs serving children experiencing homelessness or other educational needs. Fortunately, officials say the stolen files did not contain Social Security numbers, financial account details, driver's license numbers, passwords or parent and guardian personal information.
However, there is still plenty to be concerned about. Someone who knows a child's name, school and address could potentially use that information to create a convincing message that appears to come from a teacher or school administrator. Disability information also raises additional privacy concerns because those details are particularly personal.
This is where the story gets especially troubling. Although the breach involves California's public school system, the people whose records were stolen may now live anywhere in the United States. According to the California Department of Education, the compromised information includes records covering all students enrolled during the previous three school years. However, the affected population extends beyond those students.
The state also identifies a group of former students who left California public schools as far back as 2006 and whose transfers to another school were never confirmed with the department. That creates a situation many families may never have considered. Say your child attended elementary school in Los Angeles before your family relocated to Texas. Perhaps you graduated from a California public school years ago and now live in Florida. Your old student information could still be among the compromised records if it falls within the affected groups.
Former students who are now adults may also be eligible for the free identity-protection services being offered. Importantly, this does not mean every student attending school outside California has been affected. In a statement to CyberGuy, ETS confirmed that no other ETS customers were affected by the incident. The concern for families elsewhere comes from their past connection to California's public schools. California has roughly 5.7 million public school students, according to reporting on the breach. Since the compromised files span multiple school years, millions of people are potentially involved. Officials have not yet released a final count of unique affected individuals.
The California Department of Education and the State Board of Education are coordinating with cybersecurity specialists and other state agencies. The California Cybersecurity Integration Center is assisting with the technical investigation. Meanwhile, state officials are reviewing ETS's compliance with applicable data security requirements and its contractual obligations.
In its statement to CyberGuy, ETS said, "We have implemented additional safeguards, including enhanced monitoring, strengthened access controls, and further third-party review of our security practices." ETS says it continues monitoring for signs that the stolen information has surfaced publicly. For families, the unresolved question is what happens to the copied information next. Even without evidence of a public leak, sensitive student records in unauthorized hands create a privacy risk that deserves continued attention.
A SCAMMER HAS YOUR NAME, PHONE NUMBER AND ADDRESS. WHAT CAN THEY ACTUALLY DO?
ETS began notifying affected students and families on October 16, 2026. The state expects notifications to continue through early November. Letters and emails will explain the incident and identify the types of information involved. They will also include instructions for accessing complimentary identity-protection services. However, here's an important warning. Not receiving a notification does not necessarily mean your information is safe. Some former students may have outdated contact information on file.
Families who are concerned should visit the official California ETS incident webpage. It contains frequently asked questions and links to breach notifications available in 27 languages. You can also call the incident assistance line at 833-931-8488, Monday through Friday, from 6 a.m. to 6 p.m. Pacific Time.
ETS is offering affected current and former students 24 months of free identity theft protection. Parents or legal guardians can enroll eligible children under 18, while adults, including former students, can enroll themselves. The services are designed to help monitor for potential identity theft and provide assistance if someone misuses their personal information.
The enrollment deadline is March 19, 2027. Eligible minors who turn 18 before March 19, 2029 may also qualify for adult coverage using the activation code provided in their notification. Enrollment is free, and no credit card is required. Identity restoration assistance is also available to eligible individuals for 24 months from their notification date, even without enrolling in monitoring services. For complete eligibility details and enrollment instructions, visit the California Department of Education's official incident webpage at at cde.ca.gov/nr/in/ets-incident.asp.
Even without stolen passwords or financial account numbers, student records deserve serious attention. Here are practical steps I recommend taking if your family may be affected.
Scammers frequently use real data breaches as an excuse to send fraudulent emails. A message claiming to come from ETS or Experian could direct you to a fake enrollment website. Instead of clicking an unexpected link, open your browser and visit the official California Department of Education incident page. Follow the verified instructions from there.
Eligible families should take advantage of the 24 months of free identity-protection services being offered following this breach. Follow the enrollment instructions in your official notification and keep a copy for your records. No credit card is required.
For additional protection, consider an identity theft protection service which offers identity monitoring, alerts about suspicious activity and access to restoration specialists if identity theft occurs. Some services also offer paid family plans that can cover children, making it an option for parents concerned about protecting their family's personal information over the long term. Coverage and benefits vary by plan. See my tips and best picks on Best Identity Theft Protection at CyberGuy.com.
One of the strongest steps you can take against certain forms of identity theft is placing a security freeze on a child's credit file. The Federal Trade Commission says parents and legal guardians can request a free credit freeze for children under 16. Teenagers ages 16 and 17 can request their own freezes. Contact Equifax, Experian and TransUnion separately. Each bureau has its own process for handling minors. A freeze can make it harder for criminals to open new credit accounts using a child's identity. However, it cannot prevent every form of fraud.
Pay closer attention to unexpected emails or text messages claiming to involve school records. A scammer with access to personal details could make a fraudulent communication seem unusually credible. For example, someone might claim that your child's testing account requires immediate verification. Before responding, contact the school using a phone number you already trust. Avoid sharing personal information through unexpected links or attachments. Consider using strong antivirus software on your family's devices. It can help detect malicious links, suspicious downloads and malware hidden in fake school notifications. While it cannot recover stolen student information, it adds another layer of protection against scammers who may try to exploit the breach.

Scammers can use information found online to build a more detailed profile of you or your family. That's why I recommend considering a personal data removal service. These services can help remove personal information from data broker websites that collect and sell details such as names, addresses and phone numbers. While these services cannot retrieve information stolen in this breach, they can help reduce how much additional information is publicly available. If you're concerned about your child's information, check whether the service offers protection for minors before signing up. Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting CyberGuy.com.
Adults who may have been affected can review their credit reports for unfamiliar accounts or suspicious activity. Visit AnnualCreditReport.com to obtain free reports from the three major credit bureaus. Parents should also watch for unexpected bills or collection notices addressed to their children. Those can be warning signs that someone has misused a minor's identity. If you discover evidence of identity theft, report it through IdentityTheft.gov . The FTC provides a recovery plan to help you address fraudulent accounts and document the problem.
You can also contact your child's school district to better understand how it handles student records. Ask what information outside contractors receive and how long they retain it. Schools may have legal obligations to maintain certain records. Still, parents can ask about retention policies and security safeguards. This conversation is worthwhile regardless of where your family lives.
I've covered plenty of data breaches over the years, but this one bothers me because we're talking about children who had no choice about handing over their information. They went to school, took required tests and trusted the adults and organizations handling their records. Now, some of those details have ended up in the wrong hands. What I find especially troubling is how far back some of these records could go. Think about someone who left California years ago and has no reason to believe their old student information is still sitting on a testing company's system. That person could be living on the opposite side of the country and suddenly have to worry about a breach involving records from childhood. I appreciate that ETS is offering free identity protection, but I'd like to see schools and testing companies explain more clearly how long they keep sensitive student information and why. Parents deserve answers before a breach happens.
Should schools and outside testing companies be allowed to keep sensitive student records for years after a child leaves, or should families have more control over when that information gets deleted? Let us know by writing to us at CyberGuy.com.
