������� 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

to becoming a 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)acker that is practically

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

past step 3.

�

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 [email protected] 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

(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

temps you. (look in 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 [email protected].

�

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 a

true 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 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 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

configuration (ie. your NFS exports and anon 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

knowledge from reading some 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 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:

�

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 uebercrackers would be stuck as new machines get

added to 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 "[email protected]", you will

find it points to /dev/null. � Maybe with enough mail, it will overfill

/dev/null. � (Look in manual if confused.)

�

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.

�

3. � And probably one of the more important points is just following the

steps I have outlined for Stopping a Uebercracker.

Ok, now I feel really old. Really, really old. I got most of those shitty, shitty jokes.

I remember I had a thing with those hacking sites some years ago. Kinda cool
