Lately I have been working on my web application skills in prep of my OSCP exam and while searching for recommendations for peers, one of them was pentesterlab.
After a quick overview of the site, and I signed up and got started.
I would have to say I am pleased with the learning content they provide which covers a wide area of web application pentesting. Especially ‘Web For Pentester’ and ‘Web For Pentester II’. I highly recommend these two in particular if you’re looking for an introduction/refresher.
Here is the link if you’re interested: https://pentesterlab.com
