This is a personal portfolio by Arnau (Asher), sharing coding projects, cybersecurity notes and writeups. It is not an official service of Hack The Box, TryHackMe or GitHub.
Learning and authorised use
The writeups are educational material. Use any techniques only in systems you own or where you have explicit permission to test. A tutorial does not grant permission to access a third party’s systems.
Content and attribution
You may link to articles and repositories. Before redistributing material or code, check its applicable licence or ask for permission. Repository code follows the licence included with that repository; publication here does not create an additional code licence.
Machine images, platform names and other third-party assets remain subject to their owners’ rights. Demo articles are labelled as demonstrations and should not be treated as real machine walkthroughs.
Protected articles
Some articles require a password. Having a password permits reading the article through this website; it does not by itself grant permission to republish the content or redistribute the password.
Accuracy and availability
These are personal notes. They may contain mistakes or become outdated as tools and services change. Check commands and their effects before running them. I may update or remove content, and continuous availability is not guaranteed. Nothing in these terms limits rights or responsibilities that cannot lawfully be excluded.
External services
Links to other websites are provided for reference. Their availability, content, licences and policies are controlled by their respective operators.
