This ain't the first video of Gynvael that I recommend here. In my view, Gynvael Coldwind is one of the most knowledgeable figures in cybersecurity that I know of - who has a lot of hands-on experience.
And this hands on experience is demonstrated in his livestreams on Youtube. Would be great if we can nudge them into getting on @dtube and @dlive. But first, these platforms must not suck. For me, @dtube sucks because I keep getting errors when trying to upload videos. Otherwise, I would have most of my youtube videos on dtube as well. But, I digress...
In this livestream, Gynvael takes on 19 challenges from the Google CTF 2018 Beginners Quest. Without giving you any spoilers, if you're into cybersecurity and you'd like to scale up your skill fast, you should be hands-on following this 4 hour monster livestream.
