- VT Hacker #2
-
- courtesy of
- The Mad Hermit
-
- Well, there's some old news, so let's get it out of the way. The Novice menu
- stuff has changed slightly. Options 8-12 are no longer active. in addition,
- poking around above there gives you a simple error message.
-
- With that taken care of, we move on to:
-
- -------- COMMUNICATIONS NETWORK SERVICES --------
-
- There are ways to hack into this, but I'll do an overview of general
- info for those neophytes out there. CNS is running a ROLM phone system. Rolm
- created a telephone system a few years back, and IBM used it for voice messages
- & the like. It had bugs. It had security holes the size of Wisconsin. While
- it lasted, phreakers had a free message and conferencing system that IBM could
- do nothing about. IBM ended up buying out Rolm, and the company survived long
- enough to put out a beta version of the current Tech system at the University
- of New York.
-
- Problems arose as the illustrious hackers there showed Rolm that gross
- abuses of the system were possible. They showed Rolm the hard way.
- The Pick-Up function which isn't enabled on our system is capable of picking
- up someone else's phone, if you know their extension number. Devious people
- were answering other people's calls and transferring them to Topeka and other
- parts unknown. If they were really cruel, they Parked them there. As far as I
- know, just about all bugs left are harmless (well, mostly harmless). One thing
- to note: whenever you call CNS, the phone you are calling from is displayed
- immediately on a monitor in front of the operator.
-
- The data line has a different story. Though a few bugs exist, they
- aren't exploitable. They merely irritate. Expect them to disappear soon, as
- the technical people at CNS are very helpful and know what to do in most
- circumstances. The "Call, Display, or Modify?" prompt is your ticket to fun
- and weirdness. Normal functions include tweaking your dataline's parameters
- and speed, displaying commonly used services, and calling these services by
- typing:
- C VTLAN (or whatever name you want)
-
- Recently, a hack was discovered at this prompt. All numbers that you
- called from here went like this: #XXXX, where # is the start number, and XXXX
- is the four-digit extension. Here is a list of current start numbers:
-
-
- 1 - On Campus (not hooked up yet. Will replace 961-XXXX)
- 2 - On Campus (normal dataphones)
- 3 - Long Distance
- 4 - Special
- 9 - Off Campus Local
-
- The 4XXXX numbers are basically for CNS use, and for special mainframe
- connections. If you call VTCOSY, for example, you get a message stating that
- you are calling VTCOSY, and what modem number. These modem numbers can be
- dialed directly, leading to some interesting discoveries. Scanning these
- numbers without a program can be very time consuming, especially when you hit
- several numbers that all connect to the same mainframe. In addition, every "No
- Answer" takes one minute to do, because the Net waits that long before telling
- you it hasn't connected. Below, "Dead End" means that a connection was made,
- but no keypresses have any effect.

- Note that these numbers can also be dialed on the voice line. Who knows WHAT
- you'll find...
-
- You might notice that there are only 1,000 numbers of 10,000 represented.
- If you find anything else above there, let me know. Finally, there are a
- couple of ways to mess up your trail if you're paranoid or just like feeling
- secure. Call VTLAN, and then CALL 9000. This brings you back to the Net,
- through a short loop. If you really want things messed up, call 9-232-2020.
- This calls off-campus, then calls the link for getting back on the Net.
- Enjoy!
-
- The Node Router appears to be a CNS computer. The prompt is "Node[20] Enter
- Destination:" and there are 64 numbers you can type in. Some have passwords,
- some are dead ends, and others connect to other locations in the Net.
-
- Here's a list:
-
- Passworded nodes: 0,32,50
- Dead Ends: 3,4,22,28,33
- Calls the Net back: 34
- "Request:" prompt: 15
- VTLAN: 1
- Net/One: 27
-
- The Net/One prompt is the most interesting thing found yet. It's just about
- the only friendly interface ever located in CNS's part of the Net. You get to
- look at various nodes in the Net, and make connections between lines.
- Don't get your hopes up, though. My sources have only found one open link,
- but in order to figure out what it could do, they ended up closing it.
-
- Here's a list of the commands you get on the 'help' screen:
-
- The Net/One commands are:
- CONNECT Resource Name<CR>
- GET Resource Name<CR>
- LIST<CR>
- RESUME Connection Number<CR>
- ABANDON Connection Number<CR>
- EXAMINE Resource Name<CR>
- IDENTIFY Node ID<CR>
- SET DISCONNECT /New Disconnect Sequence/<CR>
- SET HOLD /New Hold Sequence/<CR>
- SET ECHO ON<CR> or OFF<CR>
- SET LINEFEEDS ON or OFF[ FOR ECHOES or INPUT or OUTPUT]<CR>
- SET BINARY ON<CR> or OFF<CR>
- SET FLOW NONE/CHARS/ENQ-ACK/SIGS/CTS-RTS/DSR-DTR/XON-XOFF[ NIU/DEVICE]<CR>
- LOGOUT<CR>
- QUIT<CR>
-
- 'Get' requests a particular line, 'Connect' opens it for use, and 'Resume'
- allows you to use it. The last command also seems to lock up the terminal...
-
- When you 'List', you get something like this:
-
- You are using port 4 of Net/One NIU-180 number 57106A, on network number 1.
- Port 4's name is "57106A4". NIU 57106A's name is "acc30".
-
- Connection 1 is unused.
-
- Your Hold Sequence is: --none--
- Your Disconnect Sequence is: <FS>OFF
-
- The Net/One command editing keys are:
- Cancel whole line: <DEL> or ^<BS> Delete last character: <BS> or ^h
- Delete last word: <CAN> or ^x Complete current word: <SP>
- Repeat last line: <SOH> or ^a
-
- ECHO mode is turned OFF.
- Automatic insertion of linefeeds after carriage returns is turned OFF.
-
- Recently (as of 10/19/88), the number 40062 has gone out of service due to use
- by certain individuals (heh heh heh). There is another way of getting to it,
- which will be detailed in the forthcoming VT Hacker #3. The above data was
- gathered using a script file for Red Ryder. Don't try to comprehend what it
- does. It works. The Net kicks you off after five unsuccessful attempts at
- connection, making this simple incremental scanner procedure slow, and painful.
- A scanner for LocalNet is in the works, and will definitely be faster due to
- the unlimited tries LocalNet allows you. We're looking for 20+ tries per
- minute, but in the meantime, here's the CNS-CBX scanner:
-
- COPYINTO ~8,ENTER NUMBER TO START AT
- (GET1)
- QUERY1 ~1
- EMPTY ~1
- IF YES JUMPTO (GET1)
- LET EQUAL `1,~1
- LET EQUAL `3,`1
- COPYINTO ~8,ENTER LENGTH OF SEARCH
- (GET2)
- QUERY1 ~2
- EMPTY ~2
- IF YES JUMPTO (GET2)
- LET EQUAL `2,~2
- ADD `3,`2
- COPYINTO ~3,`3
- SUBTRACT `1,1
- (NEXT)
- ADD `1,1
- TEST `1=~3
- IF YES JUMPTO (QUIT)
