The package presents itself as a deterministic WASM slot-math engine, but slot_engine.wasm embeds obfuscated Node.js modules and Emscripten JS shim helpers that implement a full remote-access and credential-theft toolkit against the consumer host. On invocation, an embedded module opens a Node require/createRequire context, POSTs an installer-identifying id to a remote HTTPS endpoint on a jittered polling loop, and executes the returned code via new Function(code)(require) — giving the operator arbitrary code execution on every poll. WASM-imported helpers additionally: download a Windows .exe installer over HTTPS (following redirects) to a temp path and spawn it detached with the silent-install flag /S; fetch and extract a macOS .pkg via xar -x; and write #!/bin/sh + exec node polyglot wrapper scripts with mode 0755. Separate helpers enumerate Chromium-family and Firefox-family browser profile directories (Chrome, Brave, Edge, Opera, Vivaldi, Chromium, Firefox, Waterfox, LibreWolf, Pale Moon) for Login Data / logins.json / Cookies / Local Storage / IndexedDB / extension wallet stores, walk the home directory for wallet/keystore/.dat files, and read shell-history dotfiles, then package matching content for exfiltration through the C2 channel. The Emscripten shim and both embedded ES modules are obfuscator.io-transformed (rotated base64 string arrays, dispatchers, arithmetic-noise constants, self-defending IIFE); legitimate Emscripten output is not obfuscated. Cover strings such as 'Compiling engine dependencies. This may take a while on initial startup...' are embedded to disguise payload staging as normal engine initialization.
