What data was exposed

What to do right now

  1. Be alert for smishing and SIM-swap attempts. Treat unexpected texts and "carrier" calls with suspicion; add a PIN/port-freeze with your mobile carrier.
  2. Watch for targeted phishing mail. A leaked home address makes postal and doorstep scams more convincing.
  3. Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
  4. Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
  5. Monitor the apps you use going forward. Clearly watches the breach record for the companies behind your apps and alerts you the moment one appears.
