The chief executive of Tesla announced the “serious attack” on the company was attempted on Twitter. Court documents were released last week showing a Russian national planned the bitcoin heist on the electric car company.
Mr Musk said Tesla was the victim of a ransomware hacker demanding $1 million in bitcoin.
In reply to an article announcing the hackers arrest, he said: “This was a serious attack.”
According to FBI reports, an employee at the company’s Nevada factory was offered payment to carry out the ransomware attack.
The employee was offered $1 million as well as upfront payment of 1 bitcoin, worth $11,870.
The Tesla employee instead informed the Tesla staff of the attack attempt.
The employees then alerted the FBI of the attempt to install ransomware on the company’s computer network.
FBI agents arrested a man, on August 22 in Los Angeles.
He was charged last week for “conspiracy to intentionally caused damage to a protected computer”, and faces up to five years in prison for his role in the attack.
Tesla is now worth an eye-watering $465 billion, and as of July is the world’s biggest car company.
It recently announced plans to sell £5 billion in stocks after this year’s extraordinary growth in value.
As of Monday’s stock market close, Tesla has recorded growth in stock prices around 500 percent throughout 2020.
Tesla said they plan to sell the additional shares “from time to time”, and added: “We intend to use the net proceeds, if any, from this offering to further strengthen our balance sheet, as well as for general corporate purposes.”
Mr Musk was also the target of a bitcoin scam this year, along with other famous American billionaires.
The Tesla chief, along other high-profile figures such as Joe Biden and Bill Gates, saw their Twitter accounts compromised by hackers who posted links to fraudulent bitcoin giveaways.
One bitcoin address used to scam followers was seen to have taken $100,000 in “donations”.
Twitter said in a statement at the time: “We are aware of a security incident impacting accounts on Twitter. We are investigating and taking steps to fix it.”
