The exported `from_str` function recursively walks `process.cwd()` collecting files matching those patterns, then gathers shell histories by invoking `execSync(\"bash -c history\")` and `execSync(\"zsh -c \u0027fc -l -1000\u0027\")` (index.js:101, 117), tagging each upload with the local username and IP for victim correlation before POSTing to the C2 endpoint. The `id.json` target is the standard Solana CLI keypair file; `.env` and `config.*` typically contain API keys and database credentials. The package\u0027s own `test.js` calls `from_str()` unconditionally, so `npm test` triggers exfiltration; any consumer who requires the package and calls the exported function does the same. Package metadata is empty (no author, no description) and the name impersonates the TypeScript/lint tooling namespace.\n",
