This is a paper will be broken into two parts, one showing 15 easy steps to becoming a uebercracker and the next part showing how to become a ueberadmin and how to stop a uebercracker.
Step 1. Relax and remain calm. Remember YOU are a Uebercracker.
Step 2. If you know a little Unix, you are way ahead of the crowd and skip
Step 3. You may want to buy Unix manual or book to let you know what
Step 4. Read Usenet for the following groups: alt.irc, alt.security, comp.security.unix. Subscribe to Phrack@well.sf.ca.us to get a background in uebercracker culture.
Step 5. Ask on alt.irc how to get and compile the latest IRC client and connect to IRC.
Step 6. Once on IRC, join the #hack channel. (Whew, you are half-way there!)
Step 7. Now, sit on #hack and send messages to everyone in the channel saying "Hi, Whats up?". Be obnoxious to anyone else that joins and asks questions like "Why cant I join #warez?"
Step 8. (Important Step) Send private messages to everyone asking for new bugs or holes. Here's a good pointer, look around your system for binary programs suid root (look in Unix manual from step 3 if confused). After finding a suid root binary, (ie. su, chfn, syslog), tell people you have a new bug in that program and you wrote a script for it. If they ask how it works, tell them they are "layme". Remember, YOU are a UeberCracker. Ask them to trade for their get-root scripts.
Step 9. Make them send you some scripts before you send some garbage file
Step 10. Spend a week grabbing all the scripts you can. (Dont forget to be
Step 13. Now, to pass into supreme eliteness of uebercrackerness, you brag about your exploits on #hack to everyone. (Make up stuff, Remember, YOU are a uebercracker.)
Step 14. Wait a few months and have all your notes, etc ready in your room for when the FBI, Secret Service, and other law enforcement agencies confinscate your equipment. Call eff.org to complain how you were innocent and how you accidently gotten someone else's account and only looked because you were curious. (Whatever else that may help, throw at them.)
Step 15. Now for the true final supreme eliteness of all uebercrackers, you go back to #hack and brag about how you were busted. YOU are finally atrue Uebercracker.
Now the next part of the paper is top secret. Please only pass to trusted administrators and friends and even some trusted mailing lists, Usenet groups, etc. (Make sure no one who is NOT in the inner circle of security gets this.)
This is broken down on How to Become an UeberAdmin (otherwise know as a security expert) and How to stop Uebercrackers.
Step 2. Very Important. chmod 700 rdist; chmod 644 /etc/utmp. Install sendmail 8.6.4. You have probably stopped 60 percent of all Uebercrackers now. Rdist scripts is among the favorites for getting root by uebercrackers.
Step 3. Okay, maybe you want to actually secure your machine from the elite Uebercrackers who can break into any site on Internet.
Step 4. Set up your firewall to block rpc/nfs/ip-forwarding/src routing packets. (This only applies to advanced admins who have control of the router, but this will stop 90% of all uebercrackers from attempting your site.)
Step 5. Apply all CERT and vendor patches to all of your machines. You have just now killed 95% of all uebercrackers.
Step 6. Run a good password cracker to find open accounts and close them. Run tripwire after making sure your binaries are untouched. Run tcp_wrapper to find if a uebercracker is knocking on your machines. Run ISS to make sure that all your machines are reasonably secure as far as remote
Step 7. If you have done all of the following, you will have stopped 99% of all uebercrackers. Congrads! (Remember, You are the admin.)
Step 8. Now there is one percent of uebercrackers that have gained
Step 9. Here is the hard part is to try to convince these security experts that they are not so above the average citizen and that by now giving out their unknown (except for the uebercrackers) security bugs, it would be a service to Internet. They do not have to post it on Usenet, but share among many other trusted people and hopefully fixes will come about and new pressure will be applied to vendors to come out with patches.
Step 10. If you have gained the confidence of enough security experts, you will know be a looked upto as an elite security administrator that is able to stop most uebercrackers. The final true test for being a ueberadmin is to compile a IRC client, go onto #hack and log all the bragging and help catch the uebercrackers. If a uebercracker does get into your system, and he has used a new method you have never seen, you can probably tell your other security admins and get half of the replies like - "That bug been known for years, there just isn't any patches for it yet. Here's my fix." and the other half of the replies will be like - "Wow. That is very impressive. You have just moved up a big notch in my security circle." VERY IMPORTANT HERE: If you see anyone in Usenet's security newsgroups mention anything about that security hole, Flame him for discussing it since it could bring down Internet and all Uebercrackers will now have it and the million other reasons to keep everything secret about security.
Well, this paper has shown the finer details of security on Internet. It has shown both sides of the coin. Three points I would like to make that would probably clean up most of the security problems on Internet are as the following:
2. Security experts giving up the attitude that they are above the normal Internet user and try to give out information that could lead to pressure by other admins to vendors to come out with fixes and patches. Most security experts probably don't realize how far their information has already spread.
