| ALERT the mass media... |

| AND FOR THE LOVE OF GOD, SOMEONE NOTIFY MITCH KABAY...! |

|
| Phrack 50 is here. |
|
|

| 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. |
