While Elon Musk was busy planning how to launch his Tesla Roadster into the depths of space last month, a hacker was silently using Tesla’s computing power to mine an unknown amount of cryptocurrency.

The unidentified attackers found their way in through cracks in Tesla’s cloud environment, according to a report issued by RedLock security on February 20. The miners were able to gain access via an unprotected Tesla Kubernete console—an open source system that manages applications. Included on this console were the access credentials to Tesla’s Amazon Web Service. Once they obtained access to the console, the attackers were able to run scripts that allowed them to stealthily mine cryptocurrency.
