// PoC: Conceptual check for the malicious Bitwarden CLI version // This script simulates checking the installation timestamp and version. const fs = require('fs'); const path = require('path'); // Simulate checking package.json const packagePath = path.join('node_modules', '@bitwarden', 'cli', 'package.json'); try { const pkg = JSON.parse(fs.readFileSync(packagePath, 'utf8')); console.log(`[+] Detected Bitwarden CLI Version: ${pkg.version}`); // Check if version matches the vulnerable range if (pkg.version === '2026.4.0') { console.log("[!] WARNING: Version 2026.4.0 is potentially compromised."); console.log("[!] Malicious code may be embedded."); // Concept: The malicious code typically exfiltrates data or opens a shell. // In a real scenario, one would monitor outbound traffic or file modifications. } else { console.log("[-] Version does not match the known compromised range."); } } catch (e) { console.log("[-] Bitwarden CLI not found or error reading package.json."); }
