Volcengine is a platform of cloud services released by Bytedance in 2021 to help enterprises with digital transformation. Bytedance connection to China is well established. Sensitive data or data effective for fingerprinting and tracking are in bold.
So they use a Chinese CDN or hosting? Shocking stuff. Hilarious that a company so bad at basic security beat OpenAI.
If leaking data is intentional then there are better ways than doing it in the open. Doubly so if you supposedly are in cahoots with your hosting and Chinese government.
