| Welcome to the next generation of Phrack magazine. A kinder, gentler, Phrack. |
| A seasoned, experienced Phrack. A tawdry, naughty Phrack. A corpulent, |
| well-fed Phrack. Phrack for the whole family. Phrack for the kids, Phrack |
| for the adults. Even Phrack for the those enjoying their golden years. |
|
|
| If you thought 48 was a fluke, here is 49, RIGHT ON SCHEDULE. Full speed |
| ahead, baby. We promised timely Phrack. We promised quality Phrack. Here |
| are both in ONE CONVENIENT PACKAGE! We trimmed the fat to bring you the lean |
| Phrack. Chock full of the healthy information you need in your diet. All |
| natural. No artificial ingredients. No snake oil. No placebo effect. |
| Phrack is full of everything you want, and nothing you don't. |
| |
| This issue is the first *official* offering from the new editorial staff. If |
| you missed them, our prophiles can be found in issue 48. Speaking of 48, |
| what a tumultuous situation article 13 caused. All that wacking SYN flooding. |
| Well, it got the job done and my point across. It got vendors and programmers |
| working to come up with work-around solutions to this age-old problem. Until |
| recently, SYN-flooding was a skeleton in the closet of security professionals. |
| It was akin the crazy uncle everyone has, who thinks he is Saint Jerome. We |
| all knew it was there, but we ignored it and kinda hoped it would go away... |
| Anyway, after this issue, I hope it *will* just go away. I have done |
| interviews for several magazines about the attack and talked until I was blue |
| in the face to masses of people. I think the word is out, the job is done. |
| Enough *is* enough. " SYN_flooding=old_hat; ". Onto bigger and better things. |
|
|
| A few more quick points (after all, you want Phrack Warez, not babbling |
| daemon9). I want to thank the community for supporting me (and co.) thus far. |
| Countless people have been quite supportive of the Guild, the Infonexus, and |
| of Phrack. Time and work do permit me to get back to all of you individually, |
| so just a quick blurb here. Thank you all. I will be using Phrack as a tool |
| to give back to you, so please mail me (or any of the editors with your |
| suggestions). This is *your* magazine. I just work here. |
|
|
| Most of all, I am stoked to be here. I am giving this my all. I'm fresh, I'm |
| ready... I'm hyped + I'm amped (most of my heros don't appear on no stamps..). |
|
|
| Drop us a line on what you think of 49. Comments are encouraged. |
|
|
|
|
| Bottom line (and you *can* quote me on this): Phrack is BACK. |

| [ TNO, on the other hand, doesn't even fucking care you exist ] |
