IronWorm steals credentials and uses them to spread beyond the original victim, turning developer access into a supply chain risk. . A new campaign targeting npm has evolved past simple credential theft. Researchers identified IronWorm, a self-spreading threat. It harvests high-value Linux development secrets—SSH keys, cloud tokens, package publishing credentials. One compromised workstation becomes a launchpad for downstream supply chain attacks. This is not a get-in-and-get-out operation....

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...

Understanding DNS Security: Key Insights from O'Reilly's Guide

This article is a link to the contents of DNS Security Chapter of the O'Reilly DNS book. Why should you care about DNS security? Why go to the trouble of securing a service that mostly maps names to addresses? Let us . . . . This article is a link to the contents of DNS Security Chapter of the O'Reilly DNS book. Why should you care about DNS security? Why go to the trouble of securing a service that mostly maps names to addresses? Let us tell you a story. In July 1997, during two periods of several days, users around the Internet who typed www.internic.net into their web browsers thinking they were going to the InterNIC's web site instead ended up at a web site belonging to the AlterNIC. (The AlterNIC runs an alternate set of root name servers that delegate to additional top-level domains with names like med and porn.) How'd it happen? Eugene Kashpureff, then affiliated with the AlterNIC, had run a program to "poison" the caches of major name servers around the world, making them believe that www.internic.net's address was actually the address of the AlterNIC web server. Kashpureff hadn't made any attempt to disguise what he had done; the web site that users reached was plainly the AlterNIC's, not the InterNIC's. But imagine someone poisoning your name server's cache to direct https://www.amazon.com/ or https://www.wellsfargo.com/ to his own web server, conveniently well outside local law enforcement jurisdiction. Further, imagine your users typing in their credit card numbers and expiration dates. Now you get the idea. The link for this article located at UnixReview is no longer available. . The DNS Security Chapter in the O'Reilly DNS book covers essential practices to protect the Domain Name System, vital for internet functionality and navigation.
