New Spectre-Style 'Pathfinder' Attack Targets Intel CPU, Leak Encryption Keys and Data

Researchers have discovered two novel attack methods targeting high-performance Intel CPUs that could be exploited to stage a key recovery attack against the Advanced Encryption Standard (AES) algorithm. The techniques have been collectively dubbed Pathfinder by a group of academics from the University of California San Diego, Purdue University, UNC Chapel

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

iLeakage: New Safari Exploit Impacts Apple iPhones and Macs with A- and M-Series CPUs

A group of academics has devised a novel side-channel attack dubbed iLeakage that exploits a weakness in the A- and M-series CPUs running on Apple iOS, iPadOS, and macOS devices, enabling the extraction of sensitive information from the Safari web browser. "An attacker can induce Safari to render an arbitrary webpage, subsequently recovering sensitive information present within it using

Zenbleed: How the quest for CPU performance could put your passwords at risk

You need to turn on a special setting to stop (the code you wrote to stop [the code you wrote to improve performance] from reducing performance) from reducing security.

New Study Finds Most Enterprise Vendors Failing to Mitigate Speculative Execution Attacks

With speculative execution attacks remaining a stubbornly persistent vulnerability ailing modern processors, new research has highlighted an "industry failure" to adopt mitigations released by AMD and Intel, posing a firmware supply chain threat. Dubbed FirmwareBleed by Binarly, the information leaking assaults stem from the continued exposure of microarchitectural attack surfaces on the part of

New 'Retbleed' Speculative Execution Attack Affects AMD and Intel CPUs

Security researchers have uncovered yet another vulnerability affecting numerous older AMD and Intel microprocessors that could bypass current defenses and result in Spectre-based speculative-execution attacks. Dubbed Retbleed by ETH Zurich researchers Johannes Wikner and Kaveh Razavi, the issue is tracked as CVE-2022-29900 (AMD) and CVE-2022-29901 (Intel), with the chipmakers releasing software
