Breach Database / Experian (2015)

Yes — Experian (2015) was breached.

What happened

In September 2015, the US based credit bureau and consumer data broker Experian suffered a data breach that impacted 15 million customers who had applied for financing from T-Mobile. An alleged data breach was subsequently circulated containing personal information including names, physical and email addresses, birth dates and various other personal attributes. Multiple Have I Been Pwned subscribers verified portions of the data as being accurate, but the actual source of it was inconclusive therefor this breach has been flagged as "unverified".

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.
