What it detects

This rule detects a renamed LuaJIT interpreter named compiler.exe executing a gc.txt script, the SmartLoader stage delivered through fake AI tools targeting developers. The malware ships lua51.dll and compiler.exe alongside gc.txt so a trusted-looking binary runs an obfuscated Lua payload from a plain text file, making this pairing a reliable loader signal before infostealer retrieval.
