The exported from_str() recursively walks process.cwd() searching for secret-bearing files (.env, config.toml, Config.toml, config.json, env, id.json) and POSTs each file\u0027s contents to a hardcoded, base64-obfuscated endpoint at https://vercel-backend-five-vert.vercel.app/api/v1. A helper _gsh() additionally reads ~/.bash_history, ~/.zsh_history, fish history, and PowerShell PSReadLine ConsoleHost_history.txt, and shells out via execSync(\"bash -c history\") and execSync(\"zsh -c \u0027fc -l -1000\u0027\") to dump in-memory shell history, then ships each to the same endpoint. All sensitive strings (target filenames, exfil URL, HTTP headers, USER env var name) are base64-obfuscated and decoded at module load via a decodeStr helper, indicating intentional evasion. Any project that requires this package and invokes from_str (or runs the shipped test.js) will leak credentials and shell history to the attacker.\n",
