Microphones, on the other hand, detect sound waves and convert them into electrical signals. In the case of speakers, they play sounds by vibrating a diaphragm to create sound waves. Speakers and microphones essentially operate on similar principles: converting audio waves into electrical signals or vice versa. Once inside the system, the malware can enable audio capture through the built-in microphone and even potentially repurpose the speakers as microphones, which leads us to our next point. To achieve this, attackers typically target known vulnerabilities in operating systems or applications or use social engineering techniques to trick users into installing malware. Malicious software can infiltrate a user’s computer, smartphone, or other devices with integrated speakers and microphones and exploit those systems to record audio. ![]() The most common way to transform speakers into spying devices is through the use of malware. Let’s take a look at the various means that hackers can turn your speakers into a malicious eavesdropping device: Malware-Based Audio Capture: ![]() This has raised concerns over privacy and security, especially given that speakers are often found in private spaces such as homes, offices, and hotel rooms.
