I work directly on live Linux server incidents — from compromised systems and malware infections to high CPU usage, service crashes, and production outages. My focus is fast diagnosis, controlled recovery, and long-term hardening.

What You Need to Know Ubuntu 26.04 LTS ("Resolute Raccoon") dropped April 23, 2026. It's the latest long-term support release—15 years of support total (5 years standard, 10 more with Ubuntu Pro). If you're running 24.04 LTS, you'll

What's Happening A new privilege escalation vulnerability in the Linux kernel's RxGK module (part of the RxRPC network transport layer) now has a proof-of-concept exploit. The flaw, dubbed DirtyDecrypt (also called DirtyCBC), allows unprivileged attackers to gain root access under specific conditions. The V12

What's Happening A researcher known as Chaotic Eclipse (also called Nightmare Eclipse) released working exploit code for a Windows privilege escalation flaw that Microsoft supposedly fixed six years ago. The vulnerability, CVE-2020-17103, allows a standard user to spawn a SYSTEM-level command prompt on fully patched

Incident Summary NGINX CVE-2026-42945, a heap buffer overflow in ngx_http_rewrite_module, is actively exploited in production environments. The flaw (present since 2008) allows unauthenticated remote attackers to crash nginx worker processes or execute code with crafted HTTP requests. Affected: NGINX versions 0.6.27 through 1.

Incident Summary Grafana disclosed a compromised GitHub token that allowed unauthorized access to its codebase. The attacker downloaded the repository and attempted extortion; Grafana refused to pay and declined to negotiate. No customer data was impacted. Timeline: Attacker gained access at an undisclosed date; compromise discovered "recently" (May

Putting HTTP Basic Auth in front of WordPress admin trips up most people for two reasons: WordPress's rewrite rules eat any wp-login.php protection placed in the wrong spot, and blocking /wp-admin/ wholesale kills admin-ajax.php — breaking WooCommerce, Elementor, heartbeat API, and most plugin AJAX.

Load average is one of the most-cited and least-useful metrics on a Linux box. It conflates running and uninterruptible processes, smooths over 1/5/15-minute windows, and tells you nothing about what the system is waiting on. A load of 8 on a 16-core box could

Linux powers the internet. Cloud platforms, databases, APIs, web services, containers, and internal infrastructure all run Linux. That ubiquity makes it an enormous target. But the reason so many Linux servers get compromised isn't because Linux is inherently broken. It's because once a system is deployed,

Disclaimer: I've spent the last two weeks writing about NGINX Rift, Fragnasia, and various Linux kernel catastrophes. Linux has been hogging all the vulnerability spotlight. So when a Windows BitLocker bypass drops this week, I'm covering it not because I suddenly became a Windows security expert,

QEMU 11.0 arrived after a four-release candidate cycle with significant architecture drops, improved VM migration, and expanded CPU/architecture support. The headline: 32-bit host support is gone, and several deprecated machine types have been removed. If you're running QEMU on legacy 32-bit hardware or

Canonical released Ubuntu 26.04 LTS (Resolute Raccoon) as the latest long-term support release. Shipping with Linux 7.0, APT 3.2's native rollback features, Wayland-only GNOME 50, and significant server component upgrades, this release targets systems wanting the latest technologies with 5–15 years of

CRITICAL: A logic bug in the Linux XFRM ESP-in-TCP subsystem allows unprivileged local attackers to write arbitrary bytes to kernel memory and gain root privileges. It's been quietly disclosed, a working proof-of-concept exists, and all major Linux distributions are patching. If you're
