How to become a master Hacker

A Guide to Internet Security: Becoming an Uebercracker and Becoming an UeberAdmin to stop Uebercrackers.

This is a paper will be broken into two parts, one showing 15 easy steps uebercracker and the next part showing how to become a ueberadmin and how to stop a uebercracker. A uebercracker is a term phrased by Dan Farmer to refer to some elite (cr / h) that is practically acker
impossible to keep out of the networks.

Here's the steps to becoming 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 past.

Step 3. You may want to buy Unix manual or book to let you know what ls, cd, cat does.

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 alt.irc on how to get and compile the latest IRC client and connect to IRC.

Step 6. Once on IRC, join the channel # hack. (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 cannot 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 SUID root programs (look in the Unix manual from step 3 if confused). After finding a SUID root binary, (ie. su, chfn, syslog), tell people you have a 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 (ie. a big core file). Tell them it is encrypted or it was messed up and you need to upload your script again.

Step 10. Spend a week grabbing all the scripts you can. (Dont forget to be obnoxious on # hack otherwise people will look down on you and not give you anything.)

Step 11. Hopefully you will now have atleast one or two scripts that get you root on most Unixes. Grab root on your local machines, read your admin's mail, or even other user's mail, even rm log files and whatever you temps. (look in the Unix manual from step 3 if confused).

Step 12. A good test for true uebercrackerness is to be able to fake mail.
Ask other uebercrackers how to fake mail (because they have had to pass the same test). Email your admin how "layme" he is and how you got root, and how you erased his files, and have it appear coming from satan@evil.com.

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. in your room ready for when the FBI, Secret Service and other law enforcement agencies confinscate your equipment. Call eff.org to complain how you were and how innocent 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 a true Uebercracker.


Now the next part of the paper is top secret. Please pass only to trusted friends and administrators 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 1. Read Unix manual (a good idea for admins).

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 the 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 vendor patches Cert and 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 configuration (ie. your NFS exports and anonymous FTP site.)

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 some knowledge from reading security expert's mail (probably gained access to his mail via NFS exports or the guest account. You know how it is, like the mechanic that always has a broken car, or the plumber that has the broken sink, the security expert usually has an open machine.)

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 bug, it would be a service to the 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 to be 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 is not 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 security NOTCH in my circle." VERY IMPORTANT HERE: If you see anyone's security in Usenet newsgroups mention anything about that security holes, Flame him for discussing it since it could bring down the 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 the 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 the Internet are the following:

1. Vendors need to make security a little higher than zero in priority.
If most vendors shipped their Unixes already secure with most known bugs that have been floating around since the Internet Worm (6 years ago) fixed and patched, then most would be stuck uebercrackers as new machines get added to the Internet. (I believe Uebercracker is german for "lame copy-cat that can get root with 3 year old bugs.") An interesting note is that
if you probably check the mail alias for "security@vendor.com", you will find it points to / dev / null. Maybe with enough mail, it will overfill / dev / null. (Look in the manual if confused.)

2. Security experts giving up the attitude that they are above the normal
Internet users 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 do not realize how far their information has already spread.

3. And probably one of the more important points is just following the steps I have outlined for Stopping a Uebercracker.
