Tengu Botnet Reboots Compromised Linux Devices When Defenders Kill Its Process

A new Mirai-based botnet named Tengu has been discovered with advanced persistence capabilities, including the ability to trigger device reboots via hardware watchdog timers when its main process is terminated. Nozomi Networks Labs detected the malware spreading through Telnet brute-force attacks on Linux devices. The botnet supports at least 25 different distributed denial-of-service attack metho

Flatpak-NG sounds like bad news for systemd refuseniks

The proposed Flatpak-NG (next-generation Flatpak) would shift application isolation from bubblewrap to a new systemd component called systemd-appd, creating a hard dependency on systemd. This architectural change threatens to eliminate Flatpak support for systemd-free distributions like MX Linux, Alpine, Devuan, and Slackware, which rely on Flatpak as their primary access to cross-distribution Lin

MX Linux 25.2 provides possible refuge from AI as well as systemd

MX Linux 25.2 offers a systemd-free alternative for enterprise users seeking to avoid both systemd dependencies and emerging AI integrations in mainstream distributions. The release restores the ability to switch between init systems (sysvinit and systemd) at boot time and includes optional kernel 7.0 support, while providing robust management tools that rival Arch-based distributions. This positi

One-Character Linux Kernel Flaw Enables Local Root Access, Exploits Now Public

A critical use-after-free vulnerability (CVE-2026-23111) in the Linux kernel's nf_tables packet-filtering code allows unprivileged local users to escalate privileges to root and escape containers. The flaw was patched upstream in February 2026, but detailed working exploits have now been publicly released by Exodus Intelligence in June, significantly increasing the risk for unpatched systems.
