Despite these limitations, the technique remained effective for keyboards with clear audibility of keystrokes, including mechanical and quieter membrane keyboards. The researchers suggested that using software to obscure typing sounds could be a potential defense against such attacks in the future.
This research underscores the potential vulnerabilities associated with the increasing prevalence of microphones in various devices and the advancement of deep learning tools. As technology evolves, ensuring robust cybersecurity measures becomes essential to protect against novel attack vectors.
