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 to do if you had an account
- Turn on two-step sign-in. Enable two-factor authentication where the service offers it, preferably with an authenticator app or a passkey. A leaked password alone is then not enough to get in.
- Expect targeted phishing. Leaked contact details are used to write convincing fake messages that mention the breached company or your real name. Do not click links in unexpected emails or texts about this account; go to the site by typing its address.
- Watch for scam calls and SIM swaps. Be suspicious of calls and texts that claim to be from your bank or a courier. Ask your mobile operator for a port-out or SIM-change PIN if it offers one.
- Guard against identity fraud. Identity documents and dates of birth cannot be changed like a password. Consider a credit freeze or fraud alert where your country offers one, and be wary of anyone who 'verifies' you using those details.
- Sensitive personal data. This breach includes sensitive categories of personal data. Scammers and blackmailers use such details to pressure people. Do not pay, and report extortion attempts to the police.
