I am writing an obfuscator currently with quite a few features, as I have found no good obfuscators yet that are complex enough to be nearly impossible to deobfuscate (as of course it is impossible to reach a 100% level of obfuscation where no one can deobfuscate it).
Current obfuscation methods include flow obfuscation, string encryption, proxy calls, unique renaming scheme (create gibberish WinAPI like name), junk codes, and removing all functions (merging them with the main script), traps to prevent automated deobfuscation, debugger detection, VM detection, moving strings to other parts of scripts (functions, proxy strings, etc), exit if not compiled, file integrity check. Decompile protection is also added (nothing that violates the reverse engineering clause of the ToS, I am using a PE loader with protections built into it.)
Does anyone have any ideas for more obfuscation methods to add?
