2025: Applying Technology to Computer Mouse Espionage

Researchers at the University of California have demonstrated a working method of espionage through computer manipulators. The technology uses highly sensitive optical sensors from gaming mice to capture sound waves from the human voice. The method was called Mic-E-Mouse. Attackers can use it to listen to users' conversations. This was announced in early October 2025 by Toms Hardware.

The technology is based on the use of sensors that are installed in game mice for accurate positioning. These sensors are able to pick up the slightest vibrations, including sound waves from the human voice, a member of the research team explained.

A particular danger is the availability of such devices. Mice with a resolution of over 20,000 DPI cost less than $50, and their popularity is constantly growing. This opens up more opportunities for attackers to attack.

Special machine learning algorithms convert raw data from sensors into intelligible speech. In tests, the system showed high efficiency - the accuracy of recognition of the announcer reached 80%. The number of errors during decryption of words did not exceed 17%.

The main risk concerns gamers and users of resource-intensive applications, where network functions are often used. Attackers can inject malicious code through legitimate software. At the same time, they remain unnoticed for a long time.

Experts from the University of California recommend regularly updating device firmware. Antivirus solutions with peripheral monitoring should be used. It is important to monitor the network activity of applications in real time.

In cases where confidential information is discussed, experts advise to physically disconnect the mouse from the computer. This measure eliminates the possibility of data interception through manipulator sensors during important negotiations.^[1]
