      Bypassing authentication or checks by incorporating a statement that always returns true, and doing an ‘or’ operation with the statement being injected. It manipulates the return value of the SQL statement to make it always return true, so if the website is checking if the statement returned true to indicate, for example, the password is correct, it will now think that was the case.

        So does that imply they already knew the candidate they were hiring, and were just checking if this is the guy?

        I remember the first time I shipped a website with that SQL injection.

        It got taken over surprisingly quickly.

            I just wiped the DB and put it back online again.

            I did fix it, but had to rewrite a lot of the PHP backend, which took a couple days.

            And yes, I did release another website with SQL injection… It was a personal website for my brother and the pagination was vulnerable. I had written a simple CMS for it, but Instead of a password I just generated an obscure URL with completely open access to edit the DB directly.

            The pagination got hacked but I fixed it pretty quickly (by checking the page number was in fact a number).

            Surprisingly the CMS never got hacked before I moved him over to WordPress.

            Younger me learned a lot of web dev lessons the hard way.

            ETA: This was all when I was a teen and I had nobody in my life to teach me these things. I was self taught from a PHP book from the library.

              Ah yes, the honest days of development, when you just got your hands dirty and didn’t have to worry about expensive formal education and stupid interview tactics.

                It was fun and I learned a lot. I mostly did small time jobs for local companies and used the money for my tuition. Most sites were just static HTML, and I could program flash, so there wasn’t much risk to it.

                I am glad we have git instead of various backup folders on an ftp server, continuous integration, unit tests, and frameworks/accessible info to prevent the more basic errors.

                  There is reasons it ended, and some of them good. Sorry, got caught up in nostalgia a bit there.

                  You can still write open source stuff without needing anything besides technical knowledge, if you are in a situation where you have extra time and energy after feeding yourself.
