TL;DR
Uber says a third-party vendor, Fireworks.ai, experienced a security incident that allowed an unauthorized party to access Uber data connected to the vendor. Notices reported by TechCrunch say the information included driver’s license data, but Uber has not disclosed a nationwide total or identified every affected data type. Uber says it has not identified misuse and is offering eligible recipients credit monitoring and fraud assistance.
Uber is notifying people whose personal information was accessed through a security incident at Fireworks.ai, a vendor that had access to some Uber data. Notices seen by TechCrunch say the affected information included driver’s license data; Uber has not published a national count of affected people or identified all of the data involved.
In a breach notice filed with the California attorney general and dated November 10, 2026, Uber said a service provider told the company on October 9 that an unauthorized party had compromised the provider’s internal credentials and used them to access Uber’s account with that provider. Uber said its investigation found on October 13 that Uber data connected to the service provider had been accessed. The California filing lists October 7 as the breach date.
The regulatory notice does not name the vendor. An Uber spokesperson identified it to TechCrunch as Fireworks.ai, saying the vendor had access to some Uber data. A Fireworks spokesperson told the outlet the company had found unauthorized access to some of its systems that affected customer data. The available account describes access through a vendor, not an intrusion into Uber’s own systems.
Uber’s public sample letter leaves the affected-data field blank for recipient-specific information. TechCrunch reported that breach notices it reviewed listed driver’s license information. Uber’s filing says approximately 1,873 Rhode Island residents were affected; TechCrunch reported 2,567 people in Massachusetts and 3,430 in South Carolina. Those state figures total 7,870, but they are not a national count. TechCrunch also reported that an Illinois filing listed driver’s license information while the number affected was pending, and that California drivers were notified without a reported total.

Why License Data Raises Concern
A driver’s license number is a sensitive identifier, and its exposure can create a risk of identity-related fraud or other misuse. That risk is not the same as proof that anyone’s information has been used improperly. Uber says it has not identified misuse to date, and the available notices do not establish that fraud has occurred.
The incident also shows how information held by a technology vendor can affect people who did not choose or interact with that vendor. Drivers may need to rely on individual notices to learn which specific data was involved. Without a complete count or a public account of the affected records, recipients cannot tell from the broad state totals whether their own license information was included; their notice is the key source for that detail.
Uber says affected recipients can receive credit monitoring and fraud assistance through Cyberscout, a TransUnion company. The offer is limited by an enrollment window: recipients must sign up within 90 days of the date on their letter. Readers should check the letter for the information involved, the deadline and the instructions provided by Uber.

How the Vendor Incident Reached Uber
Fireworks’ security bulletins describe an incident beginning on October 6, Pacific time, when the company said it identified unauthorized use of internal credentials. Fireworks said an unauthorized party accessed environment variables used in evaluation jobs in a limited number of customer accounts. Its bulletins say it began notifying affected customers on October 7 and notified the customers it had identified on the evening of October 9.
Those dates broadly align with Uber’s account: Uber lists October 7 as the breach date and says a provider notified it on October 9. Uber said it immediately severed data connections with the provider and opened an investigation. The company’s October 13 finding was that compromised credentials had been used to access Uber data connected to the provider.
Fireworks later broadened its description of potential effects. In an update last revised November 9, it reported impacts to account and billing information and said a limited set of accounts also involved secrets, datasets and incomplete models. Fireworks said evidence linked the activity to a financially motivated group seeking to sell tokens obtained through unauthorized access to large language models, a practice it called “LLMJacking.” TechCrunch reported that no known group had claimed the theft. Fireworks’ statements describe its broader incident; they do not specify which system held Uber’s data or establish that every listed category applied to Uber.
““An unauthorized third party had compromised the service provider’s internal credentials and used them to access Uber’s account with the service provider.””
— Uber’s notice to affected people
What Uber Has Not Disclosed
The total number of affected people remains unknown. Uber has not provided a national count or said how many drivers it is notifying. The figures reported so far come from separate state notices and do not establish the full scope; some state totals are missing or pending.
The public sample notice also does not state which data was involved for each recipient. TechCrunch’s reporting identifies driver’s license information in notices it reviewed, but an individual letter is needed to determine what information Uber says was accessed for that person. Uber and Fireworks have not publicly identified the specific Fireworks system that held the Uber data, and the available material does not establish whether other kinds of personal information were exposed for particular recipients.
Uber’s statement that it has not found misuse is limited to the time of its notice. The source material does not confirm that the information has been used for fraud, nor does it provide a complete account of the unauthorized party’s actions. Fireworks’ attribution to a financially motivated group is the company’s assessment; no known group had claimed responsibility, according to TechCrunch.
Check Your Notice and Deadline
People who receive an Uber letter should review it for the specific information identified and the instructions for assistance. Uber says eligible recipients can enroll in Cyberscout credit monitoring and fraud assistance within 90 days of the letter date. The precise deadline will depend on the date printed on each person’s notice.
Further details may emerge as state filings are updated and Uber continues communicating with affected people. A fuller public account would need to clarify the total number notified, the data categories involved across all locations and whether investigators identify any misuse. Until then, the reported state counts should be treated as partial figures, not a confirmed nationwide total.
Key Questions
Did Uber’s own systems suffer the breach?
The available notice describes an unauthorized party using compromised credentials at a service provider to access Uber data connected to that provider. It does not describe an intrusion into Uber’s own systems.
Was driver’s license information exposed?
TechCrunch reported that notices it reviewed listed driver’s license information. The public sample letter leaves the data field blank, so recipients should check their own letter to learn what information Uber says was involved for them.
How many people were affected?
There is no confirmed national total. Uber reported about 1,873 Rhode Island residents; TechCrunch reported 2,567 in Massachusetts and 3,430 in South Carolina, with other state figures incomplete or not provided.
Has Uber found that the data was misused?
Uber said it had not identified misuse to date when issuing its notice. The available information does not confirm that the data was used for fraud, and Uber’s statement does not rule out later findings.
What help is available to people who received a letter?
Uber says recipients can access credit monitoring and fraud assistance through Cyberscout. Enrollment must be completed within 90 days of the date on the individual letter; recipients should follow that notice for details.
