Gosh I was closing the tab and noticed with the corner of my eye this title. Almost couldn't believe it - it has been so long since I remember reading Phrack and this ground breaking article in particular.

Thanks for bringing up good old memories!

Here is the Phrack archive: http://www.phrack.org/ and the article in particular (I like the design better): http://www.phrack.org/issues.html?issue=49&id=14#article
