Egor Igorevich Kriuchkov, who has been arrested in connection with the case, is alleged to have met with an unnamed Russian-born Tesla employee who had access to its computer networks.
Kriuchkov allegedly eventually offered the employee $1 million in cash or Bitcoin in exchange for inserting malware into Tesla's system that would allow hackers to occupy the automaker's information security team, the report said.
The hackers also planned to hold Tesla data hostage in exchange for ransom funds.
The information comes from a federal lawsuit filed against Kriuchkov Aug. 23 in Nevada.
