SpaceXAI’s Grok programming tool was uploading its users’ entire codebase to cloud storage

AnnouncementProductJul 14, 2026

SpaceXAI's Grok Build CLI tool uploaded users' entire codebases to Google Cloud, including files it was told not to open and deleted secrets, before the feature was disabled. Cereblab published the findings, with Dr. Lukasz Olejnik calling the data retention "excessive." Elon Musk stated all previously uploaded data will be "completely and utterly deleted." Researchers confirmed the upload no longer fires as of Monday.
