Security
The scripts on this site use a function that logs suspicious activity, such as SQL injections or cross-site scripting (XSS). After a certain number of attempts are made by a particular IP, that IP address will be automatically blocked. Any further attempts at accessing the site will result in a 403 forbidden status code. No attempt is made to distinguish between malicious actions and non-invasive pen-testing probes.
Since many IP addresses are dynamically allocated, the blocks are temporary. The minimum duration is 4 days but is longer for repeat offenders and significantly longer for egregious cases.
This is a small site supported by book sales to provide a home page for my books and open source free software. As such, there is no budget available for bounties. If the site is brought down by an attack and can't be restored from either the automated cloud backups or my offline backups, then the site will close but my content on CTAN and GitHub will remain available.
If you would like to contact me (Nicola Talbot) securely, you can use the email formed by the user name security with the Dickimaw Books domain (dickimaw-books.com). The security email address is configured to send and receive messages using OpenPGP end-to-end encryption (e2ee). The public key is listed below and expires on 2025-08-24.
