UK energy firm Npower has scrapped its smartphone app following an attack by hackers. Accounts with the energy company were targeted by a credential-stuffing attack. Affected users are being told that they must change their passwords. Npower is keeping its lips sealed as to just how many customer accounts were compromised. The energy firm has also informed the Information Commissioners Office (ICO) about the attack. It is telling customers to make payments, view bills, and enter meter readings via its official website instead.”]
