Vulnetix · Advisory published July 20, 2026

Part of Island's documented AgentBaiting campaign (~7,600 malicious GitHub repositories from ~6,600 profiles; 800+ disguised as AI Skills or MCP servers). The repo distributes a ZIP containing a launcher script, a renamed LuaJIT runtime (luau.exe), and an obfuscated Lua payload disguised as a text/icon/license file. Execution runs SmartLoader, which persists via scheduled tasks in %LOCALAPPDATA% and delivers the StealC infostealer (browser passwords, cookies, sessions, extension data, email/remote-access credentials, screenshots, host info). C2 commands are resolved from a value stored in a Polygon smart contract. Malicious ZIP artifact SHA-256: 39f215bc3481a82b2c7dd2ed08213406a4625e420ceb1d07c1fa36552b634dfd Contents: launcher (.cmd/.bat), renamed LuaJIT runtime (luau.exe), obfuscated Lua payload disguised as .txt/.ico/license. Launcher executes: start luau.exe ico64.txt -> SmartLoader -> StealC infostealer.
