New Privacy Threat: AI Steals Keystrokes

Posted by

Researchers at Cornell University have unveiled a new privacy threat posed by artificial intelligence. They have developed a deep learning model that can record and steal users’ data by listening to their keystrokes. The model achieves a remarkably high accuracy rate of 95% when trained on keystrokes recorded by a nearby phone, without the use of a language model.

To accomplish this, the researchers used a data-gathering method known as a sound-based side channel attack. They first recorded the keystrokes and then trained an algorithm to recognize and connect specific sounds to specific keystrokes. The reliability of the model was found to be surprisingly accurate, especially when users were using mechanical keyboards, which produce louder sounds than average laptop keyboards.

The researchers conducted tests using online calling services like Zoom and Skype. The algorithm achieved a success rate of 93% when the audio of typing was recorded over Zoom and 91% accuracy rate with Skype calls. The implications of this research are significant, as hackers could potentially record personal information without users being aware of it.

In light of this new threat, the researchers recommend a few countermeasures to mitigate the risk. They suggest changing typing styles or using randomized passwords to counter the recordings. Additionally, users could employ software that reproduces keystroke sounds, white noise, or audio filters as a protective measure.

The discovery of this sound-based side channel attack raises concerns about the security of sensitive information. Hackers can now target data entry processes through acoustics, making it necessary for individuals and organizations to consider additional security measures.

One of the factors that contribute to the accuracy of the deep learning model is the type of keyboard being used. Mechanical keyboards, typically louder than laptop keyboards, are easier to detect sounds from and thus would result in higher accuracy rates.

The researchers believe that this method of clandestinely recording keystrokes has serious implications for privacy and data security. The threat of this sound-based side channel attack can potentially expose personal information and compromise user privacy.

The research conducted by Cornell University presents a novel approach that showcases the power of artificial intelligence to breach privacy. By listening to typing sounds, hackers can record and steal personal data, highlighting the need for users to be vigilant about their cybersecurity habits.

Since sound-based side channel attacks utilize existing acoustic information, the potential for exploitation is concerning. The development of this deep learning model underscores the importance of developing robust security protocols to safeguard user information.

In order to protect against this new type of privacy attack, it is recommended that users take proactive measures. Modifying typing styles and implementing randomized password generation can help reduce vulnerability to sound-based data collection techniques.

The revelation of this sound-based side channel attack highlights the urgent need for software and hardware manufacturers to implement countermeasures. The integration of audio filters, white noise, or other protective measures may significantly reduce the risk of data theft through covert audio recordings.

To combat the growing risks associated with sound-based side channel attacks, individuals and organizations must prioritize security awareness. Implementing best practices, such as keeping software and security systems up to date, can help minimize the potential impact of these privacy threats.

The current research offers valuable insights into the remote acquisition of sensitive information through sound-based side channel attacks. By accurately recording and analyzing typing sounds, hackers can exploit this acoustic vulnerability to compromise privacy, emphasizing the need for continual advancements in cybersecurity defenses.

Efforts to protect against sound-based side channel attacks should encompass a multi-layered approach. These strategies may include enhancing security software, educating users about potential risks, and encouraging the adoption of privacy-conscious behaviors while conducted sensitive activities online.
