TL;DR
Uber has begun notifying people whose data was accessed through Fireworks AI, a third-party vendor, after the vendor reported compromised internal credentials. Notices seen by TechCrunch say driver’s license information was involved, but Uber’s public sample notice leaves the affected-data field blank and no national total has been disclosed.
Uber is sending breach notices to people whose personal information was accessed through Fireworks AI, a third-party vendor, after the vendor said unauthorized users compromised internal credentials. Notices reviewed by TechCrunch say the exposed information includes driver’s license details, although Uber’s public sample letter does not specify the data involved in each person’s case.
In a 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 third 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 had been accessed. The filing lists October 7 as the breach date.
The regulatory notice does not name the vendor. An Uber spokesperson identified it as Fireworks AI in a statement to TechCrunch, saying the vendor had access to some Uber data. Fireworks separately confirmed to TechCrunch that a security issue involving unauthorized access to some of its systems affected customer data. The notices reviewed by TechCrunch identify driver’s license information, but Uber’s public sample letter leaves the affected-data field blank for the recipient-specific details.
The state figures disclosed so far are incomplete. Uber’s filing says about 1,873 Rhode Island residents were affected. TechCrunch reported notices listing 2,567 people in Massachusetts and 3,430 in South Carolina; those three figures total 7,870. TechCrunch also reported that an Illinois filing listed driver’s license information but said the number of affected residents was pending. California notices have been reported, but no count was given. No national total has been disclosed.
Uber says it has not identified misuse of the data to date. Affected recipients are being offered free credit monitoring and fraud assistance through Cyberscout, a TransUnion company. The notice says enrollment must be completed within 90 days of the letter date; recipients should check their own letter for the enrollment instructions and deadline.

Why License Data Raises Risk
A driver’s license number and related identifying details can be useful to criminals attempting identity fraud or impersonation. Exposure does not mean a person has already suffered fraud, and the available information does not establish that anyone has misused the data. But license details are more sensitive than ordinary contact information: they can be combined with other personal data to make fraudulent requests or account changes appear more convincing.
The reported vendor route also matters. Uber says the access involved its account with a service provider, rather than describing an intrusion into Uber’s own systems. Personal data can be exposed through outside services that handle it, so customers may have limited visibility into which vendors process their information. The incident puts the practical burden on recipients to read their notice, use the offered assistance if appropriate, and watch for suspicious activity.

How the Vendor Incident Reached Uber
Fireworks AI provides a platform for running and customizing open artificial intelligence models for businesses. In its security bulletins, Fireworks said it identified unauthorized use of internal credentials on October 6. The company said an unauthorized third party accessed environment variables used in evaluation jobs in a limited number of customer accounts. Fireworks said it began notifying affected customers on October 7 and reported notifying identified affected customers on the evening of October 9, Pacific time.
Fireworks’ dates broadly align with Uber’s account of receiving a vendor alert on October 9 and its filing’s October 7 breach date. The companies have not said which Fireworks system held the Uber data or precisely how the driver’s information was connected to the accessed environment. Fireworks’ bulletin, last revised November 9 according to the supplied source material, describes broader effects for some accounts, including account and billing information and, for a limited set, secrets, datasets and incomplete models. Those statements concern the vendor incident overall and do not establish that each category involved Uber or its drivers.
““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, in its notice to affected people
What the Notices Do Not Specify
The total number of affected people, including the number of Uber drivers who received notices, remains unknown. Available counts come from individual state filings and reports, not a companywide tally. Uber has not publicly provided a national figure in the material cited here, and at least one state count was still pending.
It is also unclear exactly which information was accessed for each recipient, how the driver’s license details were stored or linked to the vendor account, and whether the incident involved data beyond what is described in the individual letters. The public sample notice leaves its data field blank, so recipients must consult their own notice. Uber says it has found no misuse to date; the source material does not establish whether later misuse has occurred. Fireworks has described the incident as financially motivated and linked it to attempts to sell unauthorized access to AI resources, but no group had claimed the theft according to TechCrunch.
Steps for Notified Drivers
Anyone who receives a letter should first confirm the notice’s date and read the section identifying the specific information involved. If it says driver’s license information was accessed, recipients can follow the letter’s instructions for the Cyberscout monitoring and fraud-assistance offer and enroll within 90 days of the letter date. The available source material does not describe separate instructions for replacing a license, so recipients should check with the relevant state motor vehicle agency if their notice or circumstances warrant it.
Recipients can also monitor financial and online accounts for unexpected activity, review credit reports, and be cautious about messages that use personal details to request money, passwords or verification codes. These are protective steps, not evidence that fraud has occurred. Uber and Fireworks have not provided a public national count in the cited material. Further state filings or company updates may clarify the scale and data involved; affected people should rely on their individual notice for details specific to them.
Key Questions
What happened in the Uber data incident?
Uber says a third-party vendor notified it on October 9, 2026, that compromised internal credentials had been used to access Uber data connected to the vendor account. Uber identified the vendor as Fireworks AI in a statement to TechCrunch.
Was driver’s license information exposed?
TechCrunch reported that breach notices it reviewed included driver’s license information. Uber’s public sample notice leaves the affected-data field blank, so each recipient should check their own letter to learn which information was involved in their case.
How many people were affected?
A national total has not been disclosed. The figures cited so far include about 1,873 people in Rhode Island, plus 2,567 in Massachusetts and 3,430 in South Carolina according to TechCrunch. An Illinois count was pending, and the three reported figures do not establish the full scope.
What should someone do after receiving a notice?
Read the letter to identify the data involved and follow its instructions for free monitoring and fraud assistance through Cyberscout. Enrollment must occur within 90 days of the letter date. Monitor accounts for suspicious activity and use the contact details in the notice if you need clarification.
Has Uber reported that the data was misused?
Uber said it had not identified misuse to date when it issued the notice. That statement reflects the company’s findings at that time; it does not establish whether misuse may emerge later.
