Recommended actions

  • Change your Disk Union password immediately, and update it anywhere you reused the same password.
  • Enable two-factor authentication on the affected account and on your critical services (email, banking).
  • Watch for targeted phishing emails referencing Disk Union — attackers weaponise breach data quickly.
  • Stay alert for smishing (SMS phishing) and SIM-swap attempts using your phone number.
