A disgruntled Tesla employee sabotaged internal systems and may have given sensitive data to outside sources, according to a company-wide email sent by CEO Elon Musk and obtained by Reuters.

The employee in question, who was reportedly motivated by failing to receive a promotion, made “direct code changes” to Tesla’s internal operating systems and exporting classified information to “unknown third parties”. Musk described the sabotage as “extensive and damaging”.
