Most Well Rounded Obfuscation: Andrew T Shapiro Andrew T. Shapiro CSES/CIRES University of Colorado Campus Box 216 Boulder, CO 80309-0216 USA Judges' comments: To use: make shapiro ./shapiro & This entry has many different levels of obfuscation, and yet the source file is self documenting. :-) From time to time, run ps and look at the new processes. See shapiro.info for more information in the internals of this program. The file shapiro.alt contains a non-obfuscated version of this program. Selected notes from the author: The basic theme (pun) of this program is: "This time (everything) is not where it should be." ~~~~ My entry (shapiro.c) is mostly comment, formatted in the shape of a clock. If you strip out the comments and look at the code you will quickly realize that the comments were the important part and that the code does very little (see pun above). It writes (to stdout) another C program (shapiro_t2.c). This is the first level of obfuscation. The second program (shapiro_t2.c if you use the build/make file) prints a clock in the upper right hand corner of your VTxxx/ANSI display. Most of the surface obfuscation in the second program (shapiro_t2.c) was an attempt to make it as small as possible. You should be able to see around this with cb(1) and some more intelligent variable names. Once you get past this you will realize that the third level of obfuscation is a six member client/server hierarchy. (See the second info file for a detailed description of the algorithm.) Lint complains about: precedence confusion, K may be used before set, main() returns random value to invocation environment, value type used inconsistently, value type declared inconsistently, function argument ( number ) used inconsistently, function returns value which is always ignored, function returns value which is sometimes ignored All of which are harmless (famous last words). This may or may not work on non ASCII systems (I could not find one to test it on.) Copyright (c) 1994, Landon Curt Noll & Larry Bassel. All Rights Reserved.
