Tesla is known for autonomous driving. When it comes to autonomous driving, it is a battlefield where Tesla is risking its life, and when Tesla cars were hacked, it was said that the hacker drove autonomously while controlling a total of 20 cars at his disposal. It was also surprising to hear that the hacker was 19 years old. The hacker lives in Germany and revealed his identity on Twitter under the account Colombo, saying he controlled 20 Tesla cars in 13 countries and wanted to inform the owners. Surprisingly, Colombo, who was active on Twitter, introduced himself as a hacker and owner of Colombo Tech, where Colombo Tech is not a German-run company, but a security company operating in other countries, specializing in cybersecurity. Colombo said the reason why it was able to hack Tesla’s car was not because of Tesla’s technical defects, but because of the car owners’ fault. As mentioned above, he said that’s why he said he wanted to let Tesla owners know why it was hacked. He also said that among Tesla cars in each country, more than 25 were remotely operated in 13 countries. Colombo also revealed what can be hacked when they succeed. It said it can succeed by disabling the function recorded during parking, opening car doors and car windows, and starting a car. One thing that gives me a little goosebumps here is that it is possible to check the location of the vehicle by inquiring the location of the vehicle, and to check whether the driver is in the vehicle or not. And he said he could turn off and turn on the video by running a YouTube app on the driver’s side of Tesla. Colombo said he informed U.S. cybersecurity companies to respond to security and communicated the situation and problems involved in the hacking directly to Tesla. Still, Colombo said, “Fortunately, we couldn’t access brakes, accelerators, and steering, which are the main parts of the hacking, so we couldn’t literally drag the vehicle around or stop it as we wanted.”
