A user on X reported discovering that Grok had transferred their complete user directory to xAI servers without their knowledge or consent. The uploaded content included sensitive security credentials (SSH keys), encrypted password manager databases, personal documents, photos, and videos.

The incident raises critical questions about Grok's permissions model and data handling. If confirmed, this represents a severe privacy breach, as the service appears to have accessed and transmitted user files beyond what users likely understood they were authorizing. SSH keys and password manager databases are particularly sensitive, as compromised credentials grant access to external systems and accounts.

The post garnered significant attention on social media (234 points on Hacker News), indicating widespread concern within developer and security communities about similar risks in other AI assistants with file-system access. The incident underscores the importance of explicit user consent and transparent data policies for AI tools that interact with local files.
