Hackers breached automaker Tesla Inc.'s cloud system in an attempt to mine cryptocurrency, CNBC reported, citing cybersecurity company RedLock.
RedLock said the hackers deployed software called Stratum in the so-called cryptojacking attack, trying to divert the cloud's computing power toward the production of virtual money. Cloud systems enable storing and managing data over the internet.
Cryptocurrency mining involves solving complex mathematical problems to validate transactions, and are rewarded by payment in electronic tokens.
Tesla said it addressed the vulnerability within hours and did not see any initial impact on customer data protection or the safety and security of its vehicles.
"The impact seems to be limited to internally-used engineering test cars only, and our initial investigation found no indication that customer privacy or vehicle safety or security was compromised in any way," a spokesperson from Tesla reportedly said in an email.
Redlock did not specify the cryptocurrency mined in the cyber breach, CNBC said in its report.
