Scientists have discovered a new AI-driven hacking method that guesses passwords with over 90 per cent accuracy by listening to what people type on their keyboard. The cyberattack works by using AI to learn and recognise the sound profile of different keys on a keyboard, according to the yet-to-be peer-reviewed research, posted as a preprint in arXiv. Using a smartphone-integrated microphone listening for keystrokes on an Apple MacBook Pro, researchers, including Joshua Harrison from Durham University in the UK, could reproduce the exact keys with 95 per cent accuracy. Scientists also tested the accuracy of the AI system during a Zoom call, recording the keystrokes using the laptop’s microphone during a meeting. In this approach, the AI model was found to 93 per cent accurate in reproducing the keystrokes and in another test using Skype, the model was found to be about 92 per cent accurate. Researchers say the new cyberattack method is facilitated by advancements over the last decade in the number of microphones within acoustic range of keyboards. The model works by recognising the unique patterns with which users press keys on their keyboard, including the sound, the intensity and time of each keystroke. Researchers used a MacBook Pro to test the concept, helping the system recognise patterns first by pressing 36 individual keys 25 times a piece. They used an iPhone 13 mini, kept 17 cm away from the keyboard, to record the keystroke audio for their first test. They then recorded the laptop keys over Zoom, using the MacBook’s built-in microphones. This new technique using the trio of AI, microphones, and video calls “present a greater threat to keyboards than ever,” scientists warn in the study. “When trained on keystrokes recorded by a nearby phone, the classifier achieved an accuracy of 95 per cent, the highest accuracy seen without the use of a language model,” scientists write in the study. However, scientists say the AI system does not easily work the same way for every keyboard. They say the AI model must be trained separately for each keyboard, providing additional references to understand what character each keystroke corresponds to. The study says people can mitigate these kinds of attacks if they change their typing style. Scientists found that touch typing reduced the keystroke recognition accuracy from between 64 per cent to 40 per cent. They also recommend the use of randomised passwords featuring multiple cases as means of defence against such attacks. Since large language models such as ChatGPT are able to predict succeeding characters to complete words, scientists say passwords containing full words may be at greater risk. Randomly generated fake keystrokes to transmitted audio was also found to reduce the risk of such password theft. Using biometric password like fingerprint or face scanning instead typed ones can also help mitigate risk of such cyber attacks, researchers say.

Tesla’s “Master of Coin” has stepped down after working at the Elon Musk-owned electric vehicle company for over 13 years. Zachary Kirkhorn became Tesla’s chief financial officer four and a half years ago in 2019, and was reportedly a potential successor to Mr Musk in running the EV company. The Tesla boss had dubbed him “Master of Coin” in 2021 – a reference to a title in hit TV series Game of Thrones. “During his tenure, Tesla has seen tremendous expansion and growth. Tesla thanks Mr Kirkhorn for his significant contributions,” Tesla noted in an SEC filing. Tesla’s current chief accounting officer, Vaibhav Taneja, will succeed Mr Kirkhorn, the electric automaker said on Monday. “This morning Tesla announced that I’ve stepped down from my role as Chief Financial Officer, succeeded by our Chief Accounting Officer, Vaibhav Taneja,” Mr Kirkhorn posted on his LinkedIn profile. “Being a part of this company is a special experience and I’m extremely proud of the work we’ve done together since I joined over 13 years ago,” he said. Mr Taneja previously worked as Tesla’s chief accounting officer up to March 2019, prior to which he worked as corporate controller from May 2018. It remains unclear what led to Mr Kirkhorn’s surprise decision to quit his role as Tesla’s CFO. Tesla recently announced its second quarter earnings, reporting a 20 per cent increase from the same quarter last year, better than what analysts estimated. Mr Kirkhorn’s departure also comes ahead of Tesla’s much-anticipated launch of its Cybertruck later this year. “As I shift my responsibilities to support this transition, I want to thank the talented, passionate, and hard-working employees at Tesla, who have accomplished things many thought not possible,” he said. Tesla shares dropped by about 3.5 per cent on Monday following the news, and continued to fall as the market opened. Mr Kirkhorn is expected to stay on till the end of 2023 to assist his successor with the transition. “I would like to thank Zach Kirkhorn for his many contributions to Tesla over the course of 13 often difficult years,” Mr Musk tweeted.

Hackers claim to have figured out how to unlock self-driving updates and other premium features on Tesla vehicles without paying for them. The group of researchers from TU Berlin who discovered the “jailbreak” claim that it is unpatchable, meaning the electric car maker will not be able to prevent people from exploiting the hack without replacing the actual hardware of the vehicles. “Tesla has been known for their advanced and well-integrated car computers, from serving mundane entertainment purposes to fully autonomous driving capabilities,” the researchers wrote in a briefing that detailed their discovery. “More recently, Tesla has started using this well-established platform to enable in-car purchases, not only for additional connectivity features but even for analogue features like faster acceleration of rear heated seats. “As a result, hacking the embedded car computer could allow users to unlock these features without paying.” The cyber attack targets Tesla’s Media Control Unit (MCU) infotainment system found on all recent models, using a technique known as voltage glitching to take advantage of a known flaw with the AMD processor in the MCU. The attack exposes personal information, such as contacts and appointments, however it requires physical access to the car in order to work. Premium features that Tesla blocks behind a paywall include Acceleration Boost, costing $2,000, and Full Self-Driving, which costs $15,000. Not all software upgrades were tested by the researchers, and it is not clear if the hack would unblock all of them. The exploit will be presented at the Black Hat cyber security conference in Las Vegas on Wednesday, 9 August, in a presentation titled ‘Jailbreaking an electric vehicle in 2023 or what it means to hotwire Tesla’s x86-based seat heater’.
