Great Western Rail has taken the precaution of resetting the passwords for all its customers after detecting a limited campaign of password reuse attacks.

As reported by The Register, the British train operating company detected password reuse attacks against some of its customers’ accounts. In total, it found that bad actors had targeted 1,000 accounts out of a million. The railway firm responded by notifying all affected customers and contacting the United Kingdom’s Information Commissioner’s Office (ICO).

It’s unclear what types of information the bad actors might have stolen if they were successful in gaining access to a customer’s account. In a tweet to a concerned individual, it said that it disclosed that knowledge to affected customers only and did not make it publicly known.

Great Western Rail told The Register the incident was limited in scope. But that didn’t stop it from sending out an email to all account holders informing them it had reset their passwords and that they’d need to protect their accounts with a new combination.

Some customers thought the email from Great Western Rail was a scam.
