Planet GNOME - Enj, 15/10/2026 - 12:00pd

On September 22 we released systemd v262 into the wild.

In the weeks leading up to that release (and since then) I have posted a series of serieses of posts to Mastodon about key new features in this release, under the #systemd262 hash tag. In case you aren't using Mastodon, but would like to read up, here's a list of all 35 posts:

I intend to do a similar series of serieses of posts for the next systemd release (v263), hence if you haven't left tech Twitter for Mastodon yet, now is the opportunity. My series for v263 will begin in a few weeks most likely, under the #systemd263 hash tag.

In case you are interested, here is the corresponding blog story for systemd v261, here for v260, here for v259, here for v258, here for v257, and here for v256.

Juan Pablo Ugarte: Cambalache 1.2 Released

Planet GNOME - Mër, 14/10/2026 - 10:25md

Hello, I am pleased to announce a new Cambalache release.

Cambalache is a WYSIWYG (What You See Is What You Get) tool that allows you to create and edit user interfaces for Gtk 4 and 3 applications.

This new version depends on GNOME SDK 51 and includes all new properties and types from Gtk and Adwaita! It also removes the file hash from the project file which should prevent unnecessary git conflicts.

In case you missed it, you can read more about Cambalache in version 1.0 release blog.

Cambalache’s First Major Milestone!

Imagine releasing a software solution into the market only to realize the user cannot use the app properly. They have been reporting numerous bugs, which has lowered your reputation and reliability.

Business Email Compromise with AI Enhancements and New Defense Strategies

LinuxSecurity.com - Mër, 14/10/2026 - 6:10md
Business email compromise has long involved targeted impersonation and fraudulent payment requests. Generative AI can make those established tactics faster to prepare and more convincingGenerative AI has turned BEC into a tailored, low-noise operation that mimics writing style, voice, and even video presence. This piece looks at what's actually changed under the hood, what defenders are testing in response, and why so many organizations are still structurally unprepared for it.

Maintaining DKIM Integrity for Linux-Based Email Servers in Operation

LinuxSecurity.com - Mër, 14/10/2026 - 5:39md
If you run Postfix, Exim, or OpenSMTPD on Linux, DKIM is already your problem. The private key lives on your box. If that key leaks or signing stops, your domain reputation moves without you.

Email Spoofing Techniques That Bypass Human Detection

LinuxSecurity.com - Mër, 14/10/2026 - 5:20md
You've probably trained your team to look for red flags. Odd sender names, urgent language, mismatched links. But a well-crafted spoofed email won't trip any of those wires. It looks legitimate, sounds legitimate, and often comes from a domain that passes every automated check you throw at it.

Cybersecurity Best Practices for Email Templates Enhancing Data Security

Template email is more than a design tool in the campaign of consistent communication; it also has a hidden danger.

Zero Trust for Email: Implementing Advanced Protections on Linux

LinuxSecurity.com - Mër, 14/10/2026 - 3:01md
Email threats have long outgrown spamming and obvious phishing. Attackers now exploit trust itself. They impersonate internal users, hijack legitimate threads, and abuse misconfigured configurations. Defenses like perimeter filtering or static rules are not adequate any longer. A Zero Trust model redefines the issue by eliminating implicit trust at all phases of email processing. This shift is especially important in modern Linux mail environments where services are often modular, network-exp...

QR Code Phishing Linux Quishing Risks and Mitigation Strategies

LinuxSecurity.com - Mër, 14/10/2026 - 1:41md
QR codes were originally designed for industrial logistics. They were optimized for efficiency, not security. In recent years, they have become embedded across enterprise workflows, authentication flows, ticketing systems, packaging, and internal documentation systems. That expansion has created a new attack surface.

Enhancing Linux Email Security: Identify Malicious Attachments Effectively

LinuxSecurity.com - Mër, 14/10/2026 - 1:41md
Suspicious emails rarely confess in the body. The clues live in headers, MIME parts, and tiny inconsistencies between what a message claims and what it actually delivers. If your team can read those signals quickly—and connect them to the attachment—you’ll cut off credential theft, loaders, and ransomware without slowing operations.
