The company says software engineer Alex khatilov stole files from Tesla’s internal network related to its warp drive software. Tesla alleges that khatilov moved files to his personal Dropbox account, and that he was one of only a few Tesla employees who had access to the files.

Khatilov told Tesla investigators he’forgot’ about moving files to Dropbox when they confronted him. He told the New York Post in an interview that he had unintentionally moved the files to his personal Dropbox.
