A recent breakthrough by French cybersecurity researchers has exposed a side-channel vulnerability in YubiKey 5 Series security keys. This attack demonstrates that even the most secure hardware, which is designed to protect online accounts using two-factor authentication (2FA), can be compromised under the right conditions. Overview of the Side-Channel Attack YubiKeys, often praised for their robust security, rely on the Elliptic Curve Digital Signature Algorithm (ECDSA) for encryption. The Infineon SLE78 microcontroller, which powers these devices, was thought to be secure following its numerous certifications, including from the Common Criteria for Information Technology Security Evaluation....

‘Functional, free and secure by default’, OpenBSD remains a crucial yet largely unacknowledged player in the open-source field. OpenBSD: A Brief History OpenBSD, born in October 1995, emerged from the lineage of BSD Unix. Initially, it was a fork of NetBSD, another BSD variant. The project’s primary goal was to create a highly secure and free operating system with an unwavering focus on correctness and code simplicity. Pioneering Security Innovations Strong Cryptography: OpenBSD was the first free system to ship with IPSec, even navigating the complexities of US export regulations....

A critical vulnerability has been identified in OpenSSH’s server (sshd), affecting many glibc-based systems.
