  "account": "China's second-largest AI company, Zhipu AI (also known as Z.AI), is facing a major reputation crisis after hundreds of megabytes of local workspace data were silently uploaded to online servers without user consent. Developer and blogger Ferstar noticed that the ZCode tool was compressing 313MB of files and attempting to upload them to Alibaba Cloud storage 564 times. Another blogger, Feng Ruohang, reported a similar issue where a 15KB file was successfully exfiltrated. This raises serious concerns about security and privacy for Z.AI's users. The uploading mechanism is enabled by default, with no option to disable it. Z.AI has since apologized and claimed to have fixed the issue, stating that any uploaded data has been destroyed. However, users are still left questioning the extent of the breach and how long it may have been ongoing. The company has also promised to open-source ZCode's codebase and allow third-party assessors to review it, in an effort to regain trust.",
