Security Vulnerabilities Price Tag%201security advisory authentication

We often view OpenSSH security updates through the lens of standard patch management. When a new CVE hits, we scramble to update, check our versions, and return to business as usual. But recent vulnerabilities tied to distribution-added OpenSSH GSSAPI patches are a reminder that the danger doesn't always lie in the core code; it often resides in the "convenience" features we layer on top. . These recent issues shouldn't just trigger an apt upgrade or dnf update; they should trigger a...

Security Trends Price Tag%201privilege escalation Linux security

Linux security teams are drowning. Patches, kernel updates, new CVEs every week. SSH exposed here, an old web service there, and a forgotten cron job running as root. On top of that, SIEM dashboards blink all day with alerts that all claim to be “high priority.” . It’s no surprise that people stop paying attention. The real problem isn’t a lack of data. It’s the opposite. Too much noise, not enough signal. Security teams see huge lists of vulnerabilities and thousands of alerts, but very...

Over the span of just 14 days, threat actors unleashed more than 81 million login attempts against Microsoft’s Azure command-line interface (CLI). The campaign , which security researchers at Huntress identified as an ongoing, automated password-spraying effort, successfully compromised at least 78 Microsoft accounts across 64 organizations between June 12 and June 26, 2026. . While the scale is massive, the underlying strategy is surprisingly surgical. Attackers aren't exploiting a flaw in...

The Linux Foundation has officially launched Akrites , a coordinated industry initiative designed to improve how critical open source vulnerabilities are validated, coordinated, and disclosed before patches reach downstream users. Backed by a diverse coalition—including AWS, Google, Microsoft/GitHub, Red Hat, NVIDIA, and OpenAI—Akrites establishes a shared Security Incident Response Team (SIRT) to streamline the validation, remediation, and disclosure of vulnerabilities in the foundational...

Exploring BPF Firewall bpfilter Performance Over Iptables

Generating much excitement back in 2018 was bpfilter for the potential to better Linux's firewall and packet filtering by making it more robust and performance. Recently work on this BPF-based firewall solution was renewed and the performance potential over iptables and nftables is looking very good for the future with more feature work planned around new matches and targets, containers integration, in-place upgrades support, privilege separation, and BPF code optimization support. . This year the BPF-based firewall code work was taken up by Facebook's Dmitrii Banshchikov and he's trying to push the code along now. Ahead of the next iteration of these patches, Dmitrii presented at this week's Linux Plumbers Conference on the effort. The bpfilter firewall support so far with these patches allows processing basic rules in INPUT/OUTPUT chains and translating them into XDP/TC programs. Leveraging BPF, the potential is there for security advantages, more robust firewall rule handling, and being more performant than iptables/nftables. The link for this article located at Phoronix is no longer available. . Reintroducing eBPF-centric security tool bpfilter, offering enhanced speed and protection compared to classic utilities such as iptables.. BPF Firewall, bpfilter Performance, Firewall Optimization. .
