Platforms: Unix password cracker was written on a Linux Slackware 3.0 and 3.1 running machines. It was also tested on BSDI BSD/OS 2.0 and we can say for sure that it should work on Free BSD as well. Supports platforms: 1. Linux Slackware 3.0 2. Linux Slackware 3.1 3. Red Hat Linux 4.2 4. BSDI BSD/OS 2.0 5. Free BSD 4.2 6. ULTRIX 4.3 0 VAX 7. SunOS 5.3 sun4m sparc (Solaris 2.*) System requirements: Pentium 100+, 16 Mb RAM, 4 Mb free disk space on hard drive. Packet: 1. crack.c - source code of unix password cracker. 2. crack.dic - dictionary with 350223 words. Note: you can find more dictionary files on ftp://ftp.ox.ac.uk/pub/wordlists 3. crack - compiled ELF binary file for Linux. 4. readme.1st - this documentation file. Beta testing: Beta testing has been done by "Beta testing group of Scooter corp." E-Mail: betatest () iukr bishkek su. Installation: 1. Unpack archive crack-2a.tgz 2. Compile crack.c Usage: gcc -O2 -s -o crack crack.c 3. Copy you target password file into crack working directory. Running: To run unix password cracker type in your shell prompt one of the following commands: 1. crack PasswdFile 2. crack -d PasswdFile 3. crack -f PasswdFile In first case you are running crack in step-by-step cracking mode. This mode takes a lot of time and check about 94^8 combinations. For checking one password by this method you need about 2 years. It's used for checking of short passwords which are not more than 5 characters. In second case password cracker is running in dictionary mode. It uses words from the dictionary in file "crack.dic" for cracking process. The dictionary consists of 350223 words. During the cracking process program changes each word according to the following rules: 1. xxxxxxx 2. Xxxxxxx 3. XxxxxxX In fast cracking mode crack program uses information recieving from your password file, like full name, home phone, office and other. It works enought fast (1300 accounts per 18 sec. on Pentium 100, 16 Mb). As we can see, unix password cracker checks about 1 000 000 words using dictionary mode. The guessed passwords will be saved in crack.out file. Copyright: (C) Scooter corp. Bishkek, Kyrgyzstan 1996-1997.
