.NETReactorSlayer is an open source (GPLv3) deobfuscator for Eziriz .NET Reactor.

Features & Commands:

--keep-typesKeep obfuscator types, methods, fields, etc…       False
--preserve-allPreserve all metadata tokens       False
--keep-max-stackKeep old max stack value       False
--no-pauseClose CLI immediately after deobfuscation       False
--verboseVerbose mode       False

Usage:

Just drag and drop target obfuscated assembly on it.

Known Issues:

  • If target assembly not working after deobfuscation try using --preserve-all and/or --keep-max-stack command(s).

  • Since .NETReactorSlayer does not yet have the ability to de-virtualize virtualized functions, if the target protected assembly contains virtualized functions, .NETReactorSlayer may fail to de-obfuscate some protections such as string encryption and control flow.
