It is a long time since I read this stuff, but I stumbled upon a paper discussing the non-executable stack on OSX (a trick to prevent buffer/stack overflow exploits). Ah, the good old days. And with all this markup, it’s good to see that Phrack magazine stuck to their format. It’s still the same as over 20 years ago… Well written articles, focussed on correctness and content, for the coders out there who are not afraid experimenting with some assembly. The amount of (nightly) hours that go into the research and proof of these articles are unbelievable, and it shows.
