Obfuscating VBScript Code

This page shows VBScript obfuscation done with the VBScript Formatter using the optional Obfuscation capability. It contains VBScript sample code, its obfuscated version, and the generated obfuscation map of names to mangled names.

VBScript Sample Code before Obfuscation

The obfuscator can obfuscate plain VBScript source files, or ASP script files containing VBScript. This is actually an ASP script taken from an freely downloadable bulletin board program. The source is about 500 lines long; click to see obfuscated version.

VBScript Code after Obfuscation

This is the actual obfuscated VBScript code. It was obfuscated reserving names required for external API access. Compared to the orginal, notice that VBScript comments are gone, names have been scrambled, standard constants are replaced by their value, and literal constants have had their radix twiddled. The obfuscator uses a special list provided by the user to define names that should be preserved, ensuring that public interfaces and accesses to public libraries remain valid (e.g,. "document", "write").

Obfuscated Symbol Cross Reference

The obfuscator produces a cross reference mapping obfuscated symbols to the orginal symbols, so that obfuscated code in the field can still be decoded if necessary. Notice that certain symbols are preserved (we don't show them all) to enable access to the windowing environment in which this script runs. (We provide a complete preserved word list for using with the obfuscator as part of the product). In fact, by reversing this map and running the obfuscator, you can reproduce an equivalent of the starting source file, without, of course, the comments. Of course, you can do that only if you have the map.
