I always did like the mystique of the anarchist cookbook in that it was maybe not even real, but the magic around hacking was so fun in that era. You could just download a ddos program on like limewire that was actually a keylogger and be like "I'm doing crimes!" IIRC there was a whole section on payphone hacking and how to dial at unlisted numbers (they just immediately disconnect you lol). Everyone botted runescape and there was that dubdub website that shook your computer windows.
Ideologically, I feel like getting info from many sources is better than a secret tome because it's more participatory. I kinda hate that someone published a real 'anarchist cookbook'. Security stuff always kinda reads like larping to me, but I'm also not really into computers. Presumably tails or kali devs have a guide on modern hacking stuff, but idk maybe not.
An anarchist 'anarchist cookbook' would unironically have some great bean recipes though
