QuietPrint: Protecting 3D Printers against Acoustic Side-Channel Attacks

The 3D printing market has experienced significant growth in recent years, with an estimated revenue of 15 billion USD for 2025. Cyber-attacks targeting the 3D printing process whether through the machine itself, the supply chain, or the fabricated components are becoming increasingly common. One...

Invisible Ears at Your Fingertips: Acoustic Eavesdropping Via Mouse Sensors

Modern optical mouse sensors, with their advanced precision and high responsiveness, possess an often overlooked vulnerability: they can be exploited for side-channel attacks. This paper introduces Mic-E-Mouse, the first-ever side-channel attack that targets high-performance optical mouse sensors...

Acoustic Side-Channel Attacks on a Computer Mouse

Acoustic Side-Channel Attacks ASCAs extract sensitive information by using audio emitted from a computing devices and their peripherals. Attacks targeting keyboards are popular and have been explored in the literature. However, similar attacks targeting other human interface peripherals, such as...

Making Acoustic Side-Channel Attacks on Noisy Keyboards Viable with LLM-Assisted Spectrograms' "Typo" Correction

The large integration of microphones into devices increases the opportunities for Acoustic Side-Channel Attacks ASCAs, as these can be used to capture keystrokes' audio signals that might reveal sensitive information. However, the current State-Of-The-Art SOTA models for ASCAs, including...

Using Machine Learning to Detect Keystrokes

Researchers have trained a ML model to detect keystrokes by sound with 95% accuracy. "A Practical Deep Learning-Based Acoustic Side Channel Attack on Keyboards" Abstract: With recent developments in deep learning, the ubiquity of microphones and the rise in online services via personal devices,...

New 'Deep Learning Attack' Deciphers Laptop Keystrokes with 95% Accuracy

A group of academics has devised a "deep learning-based acoustic side-channel attack" that can be used to classify laptop keystrokes that are recorded using a nearby phone with 95% accuracy. "When trained on keystrokes recorded using the video conferencing software Zoom, an accuracy of 93% was...

SUSE CVE-2013-4576

GnuPG 1.x before 1.4.16 generates RSA keys using sequences of introductions with certain patterns that introduce a side channel, which allows physically proximate attackers to extract RSA keys via a chosen-ciphertext attack and acoustic cryptanalysis during decryption. NOTE: applications are not...

Using a Smartphone's Microphone and Speakers to Eavesdrop on Passwords

It's amazing that this is even possible: "SonarSnoop: Active Acoustic Side-Channel Attacks": Abstract: We report the first active acoustic side-channel attack. Speakers are used to emit human inaudible acoustic signals and the echo is recorded via microphones, turning the acoustic system of a sma...

Researchers Find Way to Extract 4096-Bit RSA Key via Sound

A trio of scientists have verified that results they first presented nearly 10 years ago are in fact valid, proving that they can extract a 4096-bit RSA key from a laptop using an acoustic side-channel attack that enables them to record the noise coming from the laptop during decryption, using a...
