Where should you keep the files the slave masters would not want you 

to use/have on your PC?



Put all the programs you should NOT have installed on your PC inside

C:\WINDOWS or C:\WINDOWS\SYSTEM, never create subdirectories. The 

total mess and confusion (which is anyway a charachteristic of the poor 

OS we are compelled to use) can in this case be turned to our advantage :-)



(2)

How to defeat censorship software checking for files deemed "illegal"

by the slave masters and yet use the programs



Quite a lot of software allows the slave masters to know if you 

have or if you have not in your harddisk files deemed "illegal"

by them. Change the names of the *.exe files! If necessary edit the 

*.dll files too (this is slightly more complicated, since you'll 

have to hexedit a little the calling programs and procedures) 

Change the names of *.exe and *.dll files to non significant names like 

		hggq67.exe

		87771ll.dll

		etcetera

The censorship software used by your corporation will not be able to

fetch them this way (this idea was pilfered from +ORC's 4.2 :-)



(3)                       DLL taming

Modify ("tame") the *.dlls and get some "secret snoopers" for free :-)



As you will probably already have seen/studied in the students' essays 

section, a very useful form of reversing is "object oriented reversing".
Dynamic-link libraries modifying (dll-taming) is one of the most promising 
reversing activities, as many essays of our student section attest. Modern 
windoze's applications rely quite a lot onto *.dlls that are already inside 
your system, and keep a very interesting interchange of parameters (and data) 
with their functions. Nothing more simple (and obvious) than modifying these 
*.dlls in order to redirect those data wherever you fancy. This is *.dll 
taming. I won't go into too much details on the technical aspect of dll 
taming. The tools and techniques you'll use are, of course, the same that 
have been thoroughly explained in the student section (and on my tools 

page). If you are (or will be) a reverse engineer it won't be all too 
difficult, believe me.

Most of the programs and applications that the slave masters use in order 
to snoop onto you or to perform their "mysterious activities" (the one that 
you would like to "study"), do rely on *.dlls that are located like sitting 
ducks inside your /windows and /windows/system directory (MSPWL32.DLL for 
enhanced password cache security, to cite but one :-)

Well, here is one of the very few sectors where YOUR competentces should be 
by far superior to the capacities of your system administrators: it's our 
field: reversing!

"Take home" your target *.dlls and, working on your own machines, modify them 
until they will work the way YOU want (and not the way the applications of the 
system administrators expect them to :-)

You don't even need to worry much about eventual length differences between the 
untamed and the tamed dll... I have never seen any application checking the 
length of the *.dlls (there are much too many variants and versions of the 
main dlls... windoze is a total mess, never forget it :-), yet, if you want 
to go "NUMMERSICHER", don't alter their length and just patch them "inside", 
using the many tricks, like "snake-patching", explained in the student section.

Once you are ready (and you have thoroughly tested them) reinsert the transformed 
*.dll onto your machine, at work.

Nobody but you will know it (hopefully) yet you will now have some powerful 
tools as allies in your battle! You may have redirected the output (with the 
data you are interested in) to the screen or to a file (careful!) or to the 
printer, you may have tsrred an activation switch, or you may keep a copy of 
the tamed dll under another name inside your windows directory, and just 
batch it on or off when you need it (so that most of the time the real, untamed 
dll will be the one working, and your tamed one will sleep inside the directory 
under another non-meaningful name until your simple dos batch "awakes" it :-)

Imagine (just imagine, of course :-) that you modify the OpenPasswordCache 
function of the above mentioned mspwl.dll so that you will be notified (with 
the possibilities of having a look at the parameters) every time that function 
will be called... well: you are NOT using Winice or another debugger in order 
to get those data, so there is no "alien" application running onto your system. 
Everything looks "normal" from the sysad standpoint: -"stupid user sits in 
front of his stupid screen and our SuperhyperSnoopo version 4.2 checks what the 
hell he is really doing, how long and how much!". Ah! Your screen gets all the 
activities of their SuperhyperSnoopo version 4.2 instead! (or whatever they use... 
most of the time it will be an overbloated *.dll intensive app :-)
  
See: you are playing at a level that most system administrators cannot even 
understand (they would not dream of modifying a windows *.dll, they have 
enough problems with the "normal" bugged Micro$oft's own ones :-) and you 
can, if you tame wisely and if you choose wisely your target dlls, gather a 
LOT of information on your system in this way. 

(4)
Batch alternative on how to defeat censorship software checking for 
files deemed "illegal" by the slave masters when you do not need to
use the programs

Create two batch file (inside c:\windows as well), that will change
on-the-fly, when you run it, the extension of all the executable 
you should NOT have installed on your PC to *.myn and back to real:
When you are offline (or when you feel like it)

REM re3444g1.BAT
REM fuck the censors, recreate
cd c:\windows\system
ren GHHA12.myn ultima_9.exe
ren GHGG12.myn chess730.exe
ren GHHA12.myn snooplan.exe
ren GHHA12.myn bombchef.exe
REM OK, recreated names

Before being online (or going home at the evening)

REM ob3444g1.BAT
REM deceive the censors, obscure
cd c:\windows\system
ren ultima_9.exeG HHA12.myn 
ren chess730.exe GHGG12.myn
ren snooplan.exe GHHA12.myn
ren bombchef.exe GHHA12.myn
REM OK, obscured names

How to install everything you want without a CD-ROM

Buy a zip drive and use the 100 Megabyte zip cartridge in order to
install whatever you like on your PC even without a CD-ROM, and in
order to save/keep/move files as you fancy without leaving much
traces behind you. The zip connects trhrough the parallel port
and its data transfer ratio is acceptable. You may even RUN programs
from there WITHOUT LEAVING ANY PHYSICAL TRACE INSIDE YOUR PC.

(6)
How to download files on the web without leaving traces
on the http:// grep filelog of the slave masters

Never download from http:// sites, they would immediatly get
your traces through the log files. 

Get all the files that you want through ftp-mail.

(7)	Visit the site with the warez you are interested in with

        your browser, but DO NOT DOWNLOAD.

2)	Write down the exact name of the *.zip file you want.

3)	Get it through ftpmail emailed to you (this leaves traces, 

	but it is selten monitored because few know that you can

	freely download this way... you may eventually use the

	path option to get the files emailed to your home account

	or to an absent colleague whose password you happen to 

        have found)


GOOD FTPMAILERS:

(just send to each of them an email with the word "help" in the

subject and in the body. Keep in mind that some of them at times

simply do not work... just try again later):

MAIL SERVER MIT		        mail-server@rtfm.mit.edu

DEARN DE			BITFTP@DEARN

PRINCETON			BITFTP@PUCC		(files until 17.825.792 bytes!)

BRYANT			        ftpmail@ftpmail.bryant.vix.com

DNA AFFRC JP		        ftpmail@dna.affrc.go.jp

W3MAIL GMD.DE		        w3mail@gmd.de	(Max 5 Megabytes)

WWWMAIL CIESIN		        www.mail@ciesin.org

NETMOR			        wwwfmail@linux.netmor.com (QUERIES INSIDE FTP SITES!)

GARBO FI			ftpmail@garbo.uwasa.fi

GETWEB HEALTHNET		getweb@usa.healthnet.org

MOGLI DE			w3mail@mogli.gmd.de (the best one for images)

How to download images

	

I assume that there is no track on the loggings if you just save images

using the right mouse button... but you may choose to get the images

ftpmailed to you as well. See point 5 and use w3mail@mogli.gmd.de



(9)

How to get administrator rights (privileges)


	Use some resident keyboard trapper on a PC of a collegue that

has NOTHING to do with you. Damage (slightly) some obvious booting 

function of that PC, wait until the sysad's slaves come and repair it. 

Fetch the administrator slave's password afterwards and 

use it THE SAME DAY (they have most of the time rotating passwords). 

A good idea is to give privileges, inside your intranet, to a WHOLE bunch

of people at the same time, try always to be a fish among many.





(A)

How to disable Webnannys censorships


Web nannys are censorship programs whose stupidity goes beyond

belief... they block anything that is deemed "dangerous" by their 

puritan idiotic programmers... whole geocities (for instance Athen)

have been banned "en block" because somebody used somewhere the 

image of a pepper with the name "hot.gif". Few corporations are so

stupid to use this shit, but you never know... should they use these

programs, here is how to destroy them :-)




A.1.	Cyber Patrol

You need a special cracking program, you'll find it 

on the web: name= cypatrol.zip


A.2.	Net Nanny

A.2.1)	Windows 95

CTRL+ALT+DEL (Get close program menu)

Choose OCRAWARE

End Task


A.2.2)	Windows 3.1/DOS

C:\

edit config.sys

type rem in front of DEVICE=C:\NN\NNDRV.SYS


A.3.	Cybersitter

A.3.1) 	Disable totally

CD /WINDOWS

copy win.cyb win.ini


A.3.2)	Block action (still logging, see 8.3.3 below)

CTRL+ALT+DEL

end task Tcpwait

create c:\windows\temp_holder

move the file cywin0.opt there

restart internet applications... Cybersitter does not

					   block anymore


A.3.3)	Remove any record from the log file

Find file cywin.alt (usually inside c:\windows)

remove read only switch

notepad cywin.alt

remove any line that begins with the word blocked

save the file

remake it read only



(B)

How to check what's going on in your system


Start using the instruments that you ALREADY HAVE inside

the huge windows conundrum (if you don't have them, 

bring them from home):


C:\WINDOWS\NETSTAT.EXE	netstat > letsee	and then edit letssee

C:\Program Files\Common Files\Microsoft Shared\MSinfo\MSINFO32.EXE

(active modules)

C:\WINDOWS\WINIPCFG.EXE


Then fetch these two files:

ps 

kill

And use them to see/terminate the applications that are working 

on your system... you'll find an explanation inside LordClito's "old" 

essay on my student page.



(C)

First and foremost Winice is a good weapon!



Install Winice 3.2. (there is a whole project of the student section that explains 

how to fetch and use this most powerful debugger. You'll find softice 

everywhere on the web: search, or buy it, it's a very good tool and deserves it)

Find the correct drivers for your PC (you may download them from

Numega's site if you do not have them). No checking software in a 

intranet can resist the CTRL+D shot :-)



(D)

Remove all limits that the sysads have imposed on you


Use the policy editor (you'll not find it inside your machine at work, 

you'll find it HOME, on your own windows 95 cd-rom under \Admin\Apptools\Poledit 

or you'll easily fetch it from the web).

Push F8 during boot choose start without register informations (therefore 

start without limits) start poledit open register configuration delete 

all limits


IF YOU DO NOT SEE any start menu, have a look at CONFIG.SYS,

you'll find there the command

	switches /n

eliminate it and restart anew.


...And if you don't see EVEN THIS, take a look at the c:\msdos.sys 

again (thanks Ivan :-) and may be you'll see among:


[Options]

BootMulti=1

BootGUI=1

Network=1 

etcetera


the following:


BootKeys=0


-this one causes the same shit, so you have to change it to:


Bootkeys=1


Or remove it... but this would NOT be so clever, would it?



(D)

Another trick: the SAFE MODE boot



As anyone (should) know, you can boot the windows bazaar in SAFE MODE (press F8 at start 

until the windows' choose your boot menu appears).


If you do choose safe mode, you'll notice pretty interesting new possibilities, which 

were disabled in the "normal" booting configuration. Among other things you'll be able 

to choose the "update information tool" and have a look at what your sysads have made 

in the last months (and which *.dll you should "intercept", see point three :-)


As long as you are in safe mode you are, moreover, relatively 'safe', so experiment around  

a little and take note of everything in sight!


(E)

Blowfishes are for ever



Well, let's not forget all the advantages of a quick and reliable encryptor. I use blowfish 

advanced 97 beta 1 (see the reversing essay by Jon).


Blowfish advanced 97 by Markus Hahn hahn(at)flix(point)de is an extremely powerful 

(and quick) encryptor, that will blowfish all the files you want, at work and at home, 

in a couple of seconds. You may (probably) get a beta version from Markus' page at 

http://www-hze.rz.fht-esslingen.de/~tis5maha/software.html




A legitime question: should you be paranoid?

Actually no, you should not. Most of the files and data that we have on our harddisks

are perfectly legal (reversing software is not an illegal activity, you may want to

read my Is reverse engineering legal? essay), and there is 

no real need to encrypt anything whatsoever. Yet there are (at least) two sound reasons 

to blowfish a lot nevertheless:

1)	it's great spass to have everything you do encrypted at work just to 

	avoid ANY administrator's sniffing. Of course, once they find all your 

	text files blowfished they will know that you have something to hide

	(once more a good dos batch can transform all those funny secret.txt.bfa

        names into something more "neutral" like Cirrus.drv :-) yet the mere fact 

	that they wont be able to know what you are hiding is fun enough :-)

2)	it's a good PRACTICE. Once you get used to routinely blowfish your data, 

	you'll learn also to KEEP those data in some places (and not everywhere 

	inside your PC, and you'll get used to encrypt sensible data, which, in

	an epoque like the one we are living in, is a very sensible thing to do

	anyway.

No matter what the reason is, we are always constantly trying 

to get to a computer connected to Internet. One possibility is 

to get Internet connection from Public computers. There are a

couple of good advantages.


1.  You could do any kind of activity in a more obscure way (no great 

    worry of trace-back from uninvited sources, high degree of anonymity)

2.  You’ll enjoy a free Internet service (and the Web should be free, nicht wahr?)




It is still hard to get a shell account free and without giving much 

information about yourself, but this access still helps you keep up with 

news and stuff with minimized activities. Hey, it is a gateway… J


But it is not as unobstructed as it sounds. Most of these public places 

(Libraries mainly) do use restriction methods to keep people from having 

a total control of services. Some of them use a 

limitation software called KIOSK, for instance, 

which basically prevents user from 

accessing certain features of a menu, for example the "General 

Preferences" of "Options" in Netscape, or the "Connect To" field of some Windoze's  

telnet programs (you should know the POWER of telnetting if you are reading 

these pages). Now this really bores, because there are times when you 

don’t even have access to the basic Programs and Settings menus of the Start 

Button.


Now, how would one run programs, install programs, and read files from 

these restricted systems if they don’t even let you boot (Boot 

passwords)? Impossible!


Not really


#1

One of the more remarkable things on these public computers is that they 

often "forget" a nice 'old' program called TaskMan. This is a small program 

activated by pressing Ctrl+Esc at the Password Screen (yes, try to 

figure out what is the purpose :). This program will allow you the 

Run Application option, and from there you could try your luck with 

Programs. GRP (which’ll pop up all the groups of Windows that’d have 

otherwise been hidden through censorware like IKIOSK.) And then there’s 

COMMAND.COM. Mind you, you should always have a system disk with you  

not to boot from it (Network Computers) but to run some important 

programs like COMMAND.COM on your own


#2


You know, they could have killed TaskMan after finding out what you have 

been doing with it (or even 'beforehand' if the sysads are smart, which, 

fortunately, does not happen all too often). What do we do now?! No 

worry, there’s still another way. These public computers using Windoze95 

as OS always have something on their menu (duh!): confusion and random 

behaviour: source of bugs and source of delights (for us crackers :)


Chances are they’ll have at least one single program, somewhere, which 

requires a standard file input from a disk. NotePad may be disabled, Write 

may have been crippled, but the censors won't probably have maimed that 

'vital tool':  Windows Explorer. 

Let's say good old 'cracker's TaskMan' is dead, so WindowsExplorer is 

probably the only other file utility on the marketplace of your library 

computer. Well, one possible way to get to it is to start one of these 

standard file input files [write, Notepad, Netscape (if 'they' did not 

disable the 'delicate' menu options, etc) and when you get to the "Open 

File" or  "Save" or "Save AS" sections, just go ahead to one of the 

yellow folders and click the RIGHT mouse button on it. 

What do you see?! Well, there’s the silly M$ 'rightclick' list: "Open Explore" 

(YES!!!), "Cut", "Paste", "Send To", "Delete" and more... 

The big point is that You now have access to Windows Explorer. From then 

on... well... 


#3

But again, our nasty censors and sysads world is not as forgiving as the we 

hoped it would be. 

Now, what if they have also removed EXPLORER from the RightClickOnFolderList? 

"Man, that’s it. Die public computers are too heavy censored... I give up". 

Eh? Not so fast sunny boy... 

There’s one more way. There is still one more option: the "Open" section in 

the RightClickOnFolder!

You could click on anything and it would open it through the software you 

want it to. Could even be a software 'sort of'... try ProgramManager... you’ll 

be surprised.














A bag of tricks








*** One idea to play around is to get to a file browser (somehow) and if 

you find all executable programs have been disabled for direct access, try 

it 'indirectly'!

What I mean is: click on the files made for that particular program, 

then you just might be able to run the program you wanted, even if direct 

disabled. 

If not, hey, come to think of it, another hope is to have the "Browse" button 

as a choice...


*** Also try installing some programs (like PIRCH). Even though I don’t 

know why, if you are able to run them, then they’ll automatically start 

the Program Manager (no matter what the restrictions were set from the 

outside) and once you can start Program Manager you'r done!


*** Dead  end with "OneEyed" (no buttons, no buttons) with Netscape? 

Try our famous Easter Egg shortcuts! Press Ctrl+Alt+F. Then a road will 

appear, explore! Try "Netscape Home Page". Try their silly and slow search 

engines, try downloading useful programs. Try whatever... main thing is you 

break the chains and you are free to roam!




Tricks by Stacker (September 1999)


Entering a network which uses user authentication via NT domains and has the

auth. needed for logon 'vinkje' set. (vinkje is a word describing the windows

thing of checking a box, and it is also used in: hey <thisnthat> doesn't work!

Well you need to put a check somewhere)


Some networks need a usercode and password to log you on, or you won't be able

to use the machines (even). Well, i got in useing the following. type something

totally wrong. 

type it again. Try cancel a lot of times (this very often works in such

networks, cause sysadmins mostly don't even know about this one (i do, and i am

a sysadmin (at the moment))). The third time entered a wrong u/p the machine

gladly assisted me in 'hacking my way in' by pointing out: "You have entered a

wrong password, you may try to login as guest", which i promptly did, and

tataaa your on... :) 


ofcourse another way is asking the guy/gall who is at the pc to type :

start->run, winipcfg and then after he/she left, boot in safe mode and enter

the ip adres manually (so no bootp or DHCP is needed).

And you are in aswell.

Stacker
