.oO Phrack 50 Oo. Volume Seven, Issue Fifty 1 of 16 Issue 50 Index ____________________ P H R A C K 5 0 April 09, 1997 ____________________ "The Perfect Drug" START the fireworks... ALERT the mass media... CUE up the Axel-F Beverley Hills Cop music... AND FOR THE LOVE OF GOD, SOMEONE NOTIFY MITCH KABAY...! Phrack 50 is here. To celebrate this landmark event, for a limited time, we are offering *all* Phrack issues (including this one) at a special "WE-MUST-BE-OUT-OF-OUR-MINDS" rate of HALF-PRICE!! That's right! Now you can enjoy Phrack for 50% off the standard price of free! Now you can enjoy your favorite electronic zine and still have enough money left over to get those breast implants! It seems, in recent months, the mass media has finally caught onto what we have known all along, computer security _IS_ in fact important. Barely a week goes by that a new vulnerability of some sort doesn't pop up on CNN. But the one thing people still don't seem to fathom is that _WE_ are the ones that care about security the most... We aren't the ones that the corporations and governments should worry about... We are not the enemy. Phrack is often described by the mass media as an 'Underground Hacker's Zine' run by `irresponsible` youths. Compare Phrack's distribution with that of the security publications that charge just enough money to keep students and interested outsiders from reading it... Then decide who is `irresponsible`. Phrack is often criticized by professionals as giving away tools to people who aren't responsible enough to use them. The fact is, we are giving away tools to people who aren't rich enough to buy them. The parallels between Internet packet sniffing and phone wire tapping are enormous. The abuses of wire tapping by government agencies are well documented. Not so well documented, however, are similar abuses by these same agencies across key Internet access points. This is just another classic example of the Government trying to assert complete control. The Internet is, however, anarchistic by nature and dynamic by design. It resists all attempts at governing and all attempts at control. By providing a public compendium of the same knowledge, information and resources that all the money in the world can buy, we help ensure that the Internet will remain safe with the individual. Knowledge is not power. Knowledge is _empowerment_. This issue contains a great deal of C source code. Somewhere in the neighborhood of 5000 lines of C source. To facilitate painless extraction of the code and support files into an arbitrarily designated hierarchical directory structure and still maintaining readability while in `zine` format, we developed a custom extraction utility. (Good lord that was a long sentence...) Article 16 contains the source for extract.c, instructions for compilation and use can be found therein. --------------------------------------------------------------------------- Enjoy the magazine.
