What EUVA (EngineUnpacker Visual Analyzer) is

EUVA (EngineUnpacker Visual Analyzer) is a Windows application for reverse engineering and binary analysis. It brings together a hex editor, decompiler, and disassembler, with structured PE decomposition and a byte minimap. The editor’s DSL can replace byte values and save patches as .euv scripts. EUVA turns x86 and x64 binaries into C/C++ pseudocode, and its C# scripting layer supports custom decompilation methods. A plugin-extensible detector pipeline identifies packers and protectors, while YARA-X can match thousands of prebuilt rules. Listed connections include VirusTotal scanning with the user’s API key, MCP, Roslyn scripts, and external analyzers. An optional AI agent accepts a user-provided key and supports cloud services or local models; the project says local servers can be used offline. AI edits are marked with comments and can be rolled back, though the maker warns that AI may hallucinate. EUVA is free under GNU GPL v3.0. It is under active development, and experimental builds may behave unexpectedly or contain bugs.
