Fake Kernel Threads Are Hiding Backdoors on Linux Servers and Appliances
Attackers keep disguising malware as Linux kernel worker processes, but careful checks will expose the disguise On September 5, 2026, Sansec, a security firm that investigates attacks on online stores, reported that attackers were exploiting a zero-day in Magento and Adobe Commerce to install a backdoor written in Rust. The vulnerability is tracked as CVE-2026-75650 […] The post Fake Kernel Threads Are Hiding Backdoors on Linux Servers and Appliances appeared first on Eclypsium.| Eclypsium

Debugging BeagleBoard USB boot with a sniffer: fixing omap_loader on modern PCs

Prioritizing 'fasd' directories in bash, sh, and zsh shells (e.g., pinned and project directories)
The fasd command-line tool (and its maintained fork, efasd) tracks access to files and directories to provide fast navigation in Linux and UNIX shells such as sh, bash, or zsh. While the default fasd tracking works well for day-to-day shell navigation, there are a few edge cases when you have a set of core directories you always want at the top of your results: To solve this, you can use a custom fasd backend to "pin" a static list of directories so they permanently outrank regular shell hist...| James Cherti
Reducing shell prompt latency caused by fasd in Bash, zsh, or sh
The fasd command-line tool (and its maintained fork, efasd) tracks access to files and directories to provide fast navigation in Linux and UNIX shells such as sh, bash, or zsh.

eFasd (Enhanced Fasd) - A fasd fork that is optimized for faster shell prompt speed
Navigating deeply nested file systems in POSIX shells on Linux and UNIX systems often requires typing repetitive, lengthy paths. The eFasd project resolves this by maintaining a continuous record of the files and directories you access. Instead of writing out absolute paths or executing multiple cd commands, you can use default fasd aliases like j to jump to a directory, f for files, d for directories, and s for search. This lets you navigate directly to active project directories or open com...| James Cherti
Configuring Debian to run smoothly on an older desktop computer
Over the weekend, I pulled an old Dell tower out of storage to set up a dedicated machine for my daughter to use for homework and retro gaming.

Linux Lockdown and Hibernation (again)
(This is an updated version of an older post - the introduction remains the same, the technical details are different) Linux draws a distinction between code running in kernel (kernel space) and applications running in userland (user space). This is enforced at the hardware level - in x86-speak1, kernel space code runs in ring 0 and user space code runs in ring 32. If you’re running in ring 3 and you attempt to touch memory that’s only accessible in ring 0, the hardware will raise a fault.| Matthew Garrett's Blog
