Terms of use

Last updated: 3 November 2026.

Educational use

The notes on this site describe security flaws, attack techniques and defences for education, research and authorised testing. Only test systems you own or have written permission to test. You are responsible for how you use the information.

No warranty

Content is provided as is. Older notes describe software versions that may no longer exist or may have been fixed. Nothing here is professional advice for a specific system.

Content and copyright

The text on this site is original writing for this edition of the archive. Product and project names belong to their owners and are used only to identify them. You may quote short passages with a link back to the page.

External links

Links to other sites are provided for reference. Their content is their own responsibility.

Changes

These terms may change; the current version is always on this page. The site does not take correspondence about these terms.
