According to reports, after a security incident at Uber's third-party vendor Fireworks AI in October, hackers leveraged stolen internal credentials to access certain Uber data, resulting in the theft of personal information and driver's license details for thousands of drivers. Uber has notified affected drivers, with 2,567 individuals impacted in Massachusetts, 3,430 in South Carolina, and 1,873 in Rhode Island; the number of affected individuals in Illinois and California remains partially undisclosed.

Fireworks AI provides developers with access to open-source models. In this incident, customer billing information and portions of private AI data were also compromised; the company stated that attackers likely acted for financial gain, targeting tokens used to access large language models for resale.
