Device security requires designers to secure their algorithms, not only against direct attacks on the input and output, but also against side-channel attacks. This requirement is especially notable ...

A side-channel attack monitors indirect signals, like power consumption, electromagnetic radiation, or timing, to steal cryptographic keys and other secrets. While they usually target hardware – ...

Side‐channel attacks represent a significant threat to cryptographic security by exploiting unintended physical emissions from computational devices. These attacks utilise information leaked through ...

A new technical paper titled “Spill The Beans: Exploiting CPU Cache Side-Channels to Leak Tokens from Large Language Models” was published by researchers at MITRE and Worcester Polytechnic Institute. ...

ChatGPT, Gemini, Microsoft Copilot, Claude, and Perplexity app icons. Microsoft has revealed a privacy flaw that could expose what you're talking about with AI chatbots like ChatGPT, even though your ...

Some versions of Yubikeys, one of the most widely used two-factor authentication (2FA) hardware tools, are vulnerable to side-channel attacks. Thomas Roche, security expert and co-founder of NinjaLab, ...

Rated of moderate severity, the flaw affects YubiKey 5 series and Security Key Series with firmware earlier than version 5.7, and YubiHSM 2 versions prior to 2.4.0. And the devices are impossible to ...

Side-channel attacks have emerged as a critical security concern in an era of increasing reliance on virtualised environments. These attacks exploit indirect leakage—such as subtle timing variations, ...

Pixnapping could be used to steal private data, including 2FA codes. Side-channel attack abuses Google Android APIs to steal data on display. Flaw is partially patched, although a more complete fix is ...
