How to Break into Absolutely any School
Computer
As you know from our tutorial on how
to break into Windows from the console, you can break into
any computer running any operating system to which you have physical
access. The trick is to figure out, once you have complete control,
how to disable whatever program is giving you a hard time.
There are only a few possible ways for these programs to work.
Maybe all you need to do is control-alt-delete and remove it
from the list of active programs that brings up.
If this doesn't work, if you can get into DOS, you can edit
any files. Or you may need to access regedit.exe, or the startup
list, etc. You can run it from either DOS or,depending on how
good your problem program is, from Windows.
Once you can edit files, the ones you are likely to need to
alter are autoexec.bat, config.sys, anything with the extension
.pwl or .lnk, \windows\startm~1\programs\startup, and the Registry.
Look for lines with suspicious names that remind you of the name
of the program you want to disable.
You can get punched in the nose note:
Of course you could do something obvious like "format c:"
and reinstall only what you want on that box. But this will make
your teachers throw fits. Mega fits. If you want to be a hero,
make sure that you can always return any school computer to the
way it was before you hacked it.
When you are done, turn the victim computer off and then back
on again instead of a reboot with power still on. This will get
rid of anything lingering in RAM that could defeat your efforts.
Keep Clueless Kiddie
Hackers from Messing up Your School Computers
Now that you have shown your teachers that you can break absolutely
any security on any box to which you have physical access, what
next? Do you just leave your teachers feeling awed and helpless?
Or do you help them?
There is a reason why they have security systems on your school's
computers. You would be amazed at all the things clumsy or malicious
users can do.
You can do your school a world of good by using your hacking
skills to fix things so that security works much better. Here
are some basic precautions that you can offer to your teachers
to lock down school computers. (See the chapter on how to break
into Windows computers for instructions on how to do most of
these.)
1) Disable all boot keys.
2) Password the CMOS. If it already has a password, change
it. Give your teacher the new password.
3) Remove any programs that allow the user to get to regedit
or dos.
4) Programs that allow hot keys to circumvent security should
be changed, if possible, to disable them.
5) Remove programs that can't be made safe.
6) Don't make it possible for Win95/98 computers to access
sensitive data on a network disk. (The passwords can be easily
grabbed and decoded.)
7) Try really, really hard to persuade the school administration
to replace Win95 with WinNT or Win2000.
With experimentation you will figure out much more for yourself.
Since Win95/98 is a totally insecure operating system, this
will be a losing battle. But at least you will be able to keep
secure enough that those students who do break in will know enough
to not do anything disastrous by accident. As for malicious school
hackers, sigh, there will always be kewl d00dz who think "format
c:" shows they are, ahem, kewl d00dz.
You may also have a problem with school administrators who
may feel that it is inconvenient to set up such a secure system.
They will have to give up the use of lots of convenient programs.
Upgrading to WinNT or Win2K will cost money. Try explaining to
them how much easier it will be to keep those wannbe hacker vandals
from trashing the school computers or using them to visit bianca's
Smut Shack.
Are you ready to turn your hacking skills into a great reputation
at school? Are you ready to have the computer lab teachers begging
to learn from you? Are you ready to have the entire school computer
system under your control--legally? You will, of course, only
use the tricks of this chapter under the supervision of an admiring
teacher, right? It sure is more fun than expulsion and juvenile
court!
