New "GoFetch" Vulnerability in Apple M-Series Chips Leaks Secret Encryption Keys

A new security shortcoming discovered in Apple M-series chips could be exploited to extract secret keys used during cryptographic operations. Dubbed GoFetch, the vulnerability relates to a microarchitectural side-channel attack that takes advantage of a feature known as data memory-dependent prefetcher (DMP) to target constant-time cryptographic implementations and capture sensitive data

GhostRace – New Data Leak Vulnerability Affects Modern CPUs

A group of researchers has discovered a new data leakage attack impacting modern CPU architectures supporting speculative execution. Dubbed GhostRace (CVE-2024-2193), it is a variation of the transient execution CPU vulnerability known as Spectre v1 (CVE-2017-5753). The approach combines speculative execution and race conditions. "All the common synchronization primitives implemented

Third-Party ChatGPT Plugins Could Lead to Account Takeovers

Cybersecurity researchers have found that third-party plugins available for OpenAI ChatGPT could act as a new attack surface for threat actors looking to gain unauthorized access to sensitive data. According to new research published by Salt Labs, security flaws found directly in ChatGPT and within the ecosystem could allow attackers to install malicious plugins without users' consent

Researchers Uncover New GPU Side-Channel Vulnerability Leaking Sensitive Data

A novel side-channel attack called GPU.zip renders virtually all modern graphics processing units (GPU) vulnerable to information leakage. "This channel exploits an optimization that is data dependent, software transparent, and present in nearly all modern GPUs: graphical data compression," a group of academics from the University of Texas at Austin, Carnegie Mellon University, University of
