Hacker’s Manual 2025: Nineteenth Edition

Linux security is more than a matter of locking down a server. Hacker’s Manual 2025: Nineteenth Edition brings together tutorials and features on defensive security, privacy, Linux systems and the practical skills that help users understand their machines.

Compiled by Aiden Dalby and Steve Dacombe, this 148-page bookazine moves between focused security coverage and broader Linux projects. Kali, Fedora Security Lab, Tails and server protection sit alongside kernel building, data recovery and a substantial terminal reference section.

Security with Linux at the centre

The issue explores ways to strengthen servers and desktops, learn about security tools and protect online privacy. Its coverage of Kali and Fedora Security Lab gives readers an introduction to prominent security-focused environments, while articles on secure chat and Tails turn attention to private communication and everyday protection.

Explore the working parts of a Linux system

Beyond security, the tutorials range across Fedora, Linux history and kernel building. The issue also looks at rescue and repair, damaged-disk recovery, virtual machines, cloud services and monitoring. Practical projects such as multi-boot setups, Linux on a tablet and building a custom Ubuntu distribution broaden the view from the desktop to the systems around it.

A handy terminal reference

The closing terminal section takes readers through navigating files and folders, editing configuration files, checking system information and working with partitions. It also introduces remote access and core commands for Linux web server administrators. That mix makes the issue useful to browse by topic, whether you want a particular tutorial or a refresher on command-line basics.

For curious Linux users

This edition will interest Linux users who want to build practical familiarity with system tools, security ideas and open-source software. Its subjects range widely, so readers can move from a Fedora desktop feature to server security or terminal commands as curiosity leads.

For a snapshot of Linux tutorials and security topics in 2025, this edition offers plenty to explore—one system, many useful rabbit holes.
