[Fireworks AI Inference Platform Hacked, Affecting Some Customer Data] According to a recent security announcement from Fireworks on November 10th, a security incident affected customer accounts and billing information. A small number of accounts also had their keys, datasets, and incomplete model weights compromised. Fireworks stated that a third-party cloud service provider hosting its development machines experienced a security incident on October 23rd. Attackers used this opportunity to gain access to the development machines the following day and run unauthorized tasks, resulting in additional impact on customer data. The company stated that no further successful access to the platform used by its customers has been detected since October 25th. Affected information includes billing addresses, invoices, and payment records. Fireworks stated that it does not store payment card numbers, and these card numbers were not affected. The company is investigating with Palo Alto Networks' Unit 42 and has temporarily disabled the self-service dataset upload and download functions used for batch inference and dataset-based training.
