The romanticized image of the digital nomad – a laptop on a sun-drenched balcony – rarely accounts for the actual friction of maintaining a professional development environment on the move. . The friction is amplified with Linux. We are looking for a setup that respects our kernel configurations, handles volatile network handovers, and maintains a strict security posture without the hand-holding of a consumer-grade OS – so, put simply, more than just a laptop and a sunny deck. The hardware is...

Cron has existed in Unix and Linux environments for decades, handling backups, cleanup scripts, patching jobs, log rotation, monitoring tasks, and other maintenance work that administrators do not want to run manually. Most Linux servers rely on it constantly, which is exactly why attackers continue abusing it for persistence after a system has already been compromised. . Persistence through cron is not complicated. Attackers do not need a rootkit or advanced malware framework to maintain...

A major internal repository breach at GitHub has exposed a critical and overlooked blind spot in Linux supply chain security. Kernel exploits, exposed SSH services, weak firewall rules, and vulnerable daemons dominated the Linux threat model for years, and in many environments, they still matter. But recent supply-chain incidents involving GitHub ecosystems, npm packages, and malicious developer tooling point somewhere else entirely: the developer workstation. . The breach matters because...

Linux administrators often face an ugly choice in the cloud: prioritize convenience and cost-efficiency by sharing infrastructure, or sacrifice those benefits for the sake of total isolation. Most modern Linux workloads don't live on their own private servers anymore. They live in shared environments like Kubernetes clusters, where multiple teams and services run side-by-side. It sounds efficient, and it usually is. . But cloud isolation isn't as ironclad as it looks on the diagram. If you...

Managed Extended Detection and Response (MXDR) has become one of the most sought-after security services in the enterprise market — and with good reason. It promises the holy grail: broad visibility across endpoints, network, cloud, email, and identity, combined with the 24/7 human expertise most organizations simply cannot build in-house. . However, the rapid growth of the market has produced a wide range of providers whose capabilities vary considerably beneath the surface. Choosing the...

Libgcrypt 1.4.5 Launch: Important Security Updates and Performance Boosts

Libgcrypt is a general purpose library of cryptographic building blocks. It is originally based on code used by GnuPG. It does not provide any implementation of OpenPGP or other protocols. Thorough understanding of applied cryptography is required to use Libgcrypt. . Hello! The GNU project is pleased to announce the availability of Libgcrypt version 1.4.5. Libgcrypt is a general purpose library of cryptographic building blocks. It is originally based on code used by GnuPG. It does not provide any implementation of OpenPGP or other protocols. Thorough understanding of applied cryptography is required to use Libgcrypt. Noteworthy changes in version 1.4.5: * Fixed minor memory leak in DSA key generation. * No more switching to FIPS mode if /proc/version is not readable. * Fixed a sigill during Padlock detection on old CPUs. * Fixed a hang on some W2000 machines. * Boosted SHA-512 performance by 30% on ia32 boxes and gcc 4.3; SHA-256 went up by 25%. Source code is hosted at the GnuPG FTP server and its mirrors as listed at . On the primary server the source file and its digital signature is: (1121k) This file is bzip2 compressed. A gzip compressed version is also available: (1386k) .sig Alternativley you may upgrade version 1.4.4 using this patch file: (93k) The SHA-1 checksums are: ef7ecbd3a03a7978094366bcd1257b3654608d28 libgcrypt-1.4.5.tar.bz2 8d83a60ca55f2ea40b5d5bc99463905b7a1dcb56 libgcrypt-1.4.5.tar.gz 5307e361da5232cd771c300adddc69e57f0e366d libgcrypt-1.4.4-1.4.5.diff.bz2 For help on developing with Libgcrypt you should read the included manual and optional ask on the gcrypt-devel mailing list [1]. Note that this version is from the stable branch; the current development version is available at . Improving Libgcrypt is costly, but you can help! We are looking for organizations that find Libgcrypt useful and wish to contribute back. You can contribute by reporting bugs, improve the software [2],order extensions or support or more general by donating money to the Free Software movement (e.g. ). Commercial support contracts for Libgcrypt are available [3], and they help finance continued maintenance. g10 Code GmbH, a Duesseldorf based company, is currently funding Libgcrypt development. We are always looking for interesting development projects. Many thanks to all who contributed to Libgcrypt development, be it bug fixes, code, documentation, testing or helping users. Happy hacking, Werner [1] See . [2] Note that copyright assignments to the FSF are required. [3] See the service directory at . . We're excited to unveil Libgcrypt 1.4.5, featuring significant enhancements and optimizations for cryptographic software.. Libgcrypt Release, Cryptography Updates, Security Fixes. .
