- Part I
-
-
- One of the most common mainframe systems on the market and in worldwide use
- today is the IBM VM/370 system. The VM is not a computer, it is an operating
- system which may be run on a great number of systems IBM manufactures. When run
- on an IBM3081 system (the first that I broke into) it is very quick and useful.
- The VM/370 OS consists basically of two parts:
- 1) The CP level.
- 2) The CMS level.
- ----------------------------------------------
- CP level.
- The CP level is the bare-bones operating system of the VM machine. It
- simply lets the user use the IBM hardware as he wishes. This includes logging
- in, loading and rewinding tape drives, checking system status and console status
- logging out and also messaging to a user-account (logged in) or device. There
- is no accessable help facility at this level so be sure that you know what you
- are doing.
- Some useful commands: Code
- Q N -List the logged on users an their terminal locations. L
- M (username) text -Send the specified user the text. A
- * text -Send ALL users (logged in or not) text A
- Rewind Dev# -Rewind tape number xxx usually 181 L
- Force username -Force logoff of username (by system) OA
- SHUTDOWN -Close all external ports, logoff everyone
- and shut the system down. OA
- ACNT (username) - Clear account info on username, reset $ OA
- Disc HOLD -disconnect, will appear as username-DSC in
- Q N command. If the HOLD is added, will let
- you logon as a different user. L
- L (username) password memsiz A
- -Will login (username) to VM. If password is not given the
- sy+k2Kcc);b;#sV+kSB-
-
- 6d.\YlZ3ied
- after the password if it is to be used. It sets the virtual
- machine size (more on this in part 2) A
-
- Explaination of codes:
- L - logged in general user
- A - Any user at all (logged in or not)
- OA - Operator type account. Names usually are VMUTIL, IBMCE,
- OPERATOR(always), OP1, RSCS or OP2.
-
- Hacking
- So how do you go about finding a password? Well you need to get in somehow
- so try this. Use VMUTIL as the username and VMUTIL as the password. Some systems
- are so stupid that this type of password is prevalent throughout the entire
- system! Or try RSCS RSCS or OP1 OP1 or IBMCE IBMCE. In anycase the username is
- never longer than 8 chars and the system will tell you if you have hit a valid
- username or not. First names are always good too. Universities usually have the
- format DDcccuuu where:
- DD - Department (2 letters)
- ccc- course number (3 numbers like 123)
- uuu- user numbers (starts at 000 for master account, then 001 or 100)
-
- Special chars in names or passwords are not allowed. Passwords are always
- less than 9 characters, 8 is the maximum.
-
- Hint: try using the account names above and then do this:
- send a PiHnZ[[2$H Type HX <cr>
- type CP Q N to list the logged on accounts
- then try to hack those accounts!! Leave the system accounts alone.
-
- Well, that should answer some questions on getting in, in the next article I'll
- tell you what there is to do once you have got a password and account. I'll also
- talk about the CMS enviornment.
