FINDINGS ░▒▓

criticalchild_process / exec usageExecuting shell commands can be used to download and run malware, exfiltrate data, or modify system files.src/api/provider/sessions.ts

import axios from 'axios';
import { execFileSync } from 'child_process';

type ResponseSuccess = { status: number; data?: any };

criticalRemote script piped into a shellA shell script downloads remote content and executes it directly (e.g. `curl … | bash`). The payload is never stored or reviewable and can change server-side — a classic malware/backdoor install pattern.local_install.sh

        if [ ! -x "$(command -v curl)" ]; then
            log_warning "Curl não está instalado. Tentando instalar..."
