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.

It was arguably the mass shift to remote working sparked by coronavirus lockdowns which saw Zoom rapidly become a household name – but now, three years later, even the tech giant itself is extolling the benefits of a physical office. The videoconferencing firm has now told employees who live within 50 miles of an office that they should commute in at least two days each week, in a plan due to come into force over the course of the next two months. The move to what Zoom calls a “structured hybrid approach” will impact thousands of employees at 12 offices across the world, including in the UK. A spokesperson said: “We believe that a structured hybrid approach – meaning employees that live near an office need to be onsite two days a week to interact with their teams – is most effective for Zoom. “As a company, we are in a better position to use our own technologies, continue to innovate, and support our global customers. “We’ll continue to leverage the entire Zoom platform to keep our employees and dispersed teams connected and working efficiently. Additionally, we will continue to hire the best talent, regardless of location.” The company was reported to have nearly 8,500 employees at the end of 2022, but like several other big tech companies was forced to let go 15 per cent of its staff in February, amounting to some 1,300 employees, as chief executive Eric Yuan took a 98 per cent pay cut. Zoom went from having 10 million daily meeting participants in 2019– a measure which fails to account for whether one person attends multiple meetings – to 300 million the following year, as social and working lives were pushed further online by health restrictions to curb the spread of Covid-19. But the tech firm has taken a hit amid a push by many firms to get employees back into offices, with its share price falling from a high of $559 in October 2020 to $68, lower than they were prior to the pandemic. Mr Yuan faced a series of questions from employees who expressed frustration about the time and money they’d waste while commuting, during a tense meeting about the new hybrid policy last week, one employee who was present told the New York Times. The company currently employs more than 200 people at its UK office, and has this week opened a new office space in central London, which is being billed as “laying down the foundations for Zoom as a successful hybrid business”, according to The Times.
