Unit 3 The Internet 单元话题阅读理解练习 （2022秋·辽宁沈阳·高一校考期中）Researchers at the University of Alabama in Birmingham suggest that brainwave-sensing headsets (脑电波耳机), also known as EEG headsets, need better safety after a study which shows hackers (黑客) could guess a user’s bank account passwords by monitoring (监测) his brainwaves. Nitesh Saxena, professor in the UAB, and his team found that a person who stopped a video game and entered into a bank account while wearing an EEG headset was at a risk of having his passwords stolen by a bad software program. Saxena and his team used one EEG headset that could be bought by customers online to show how easily an ill software program could eavesdrop on a user’s brainwaves. While typing, a user’s reaction corresponds with his hand, eye and head muscle (肌肉) movements. All these movements are caught by EEG headsets. The team asked 12 people to type passwords into a text box as if they were entering into an online account while wearing an EEG headset, in order for the software to train itself on the user’s typing and the corresponding brainwave. The team found that when a user entered passwords, the ill software program could make educated guesses about the passwords by reading the EEG data recorded. And it just increases the chance of guessing a six-letter password from one in 500,000 to one in five. “With the growing popularity of EEG headsets and all kinds of ways they could be used, they will become part of our daily life,” Saxena said. “It is important to study the possible risks with this new technology to raise users’ awareness to the risks and develop methods of avoiding the bad attacks.” One method suggested by Saxena and his team is to make noise anytime a user types a password while wearing an EEG headset. 1．How do hackers guess passwords of a user’s bank account (账户)?
