Spotify's CTO Oskar Stal wrote on the company's blog that an internal breach allowed unauthorized access to one person's account. "Our evidence shows that only one user's data has been accessed and this did not include any password, financial or payment information." Because of the breach Spotify will ask members to re enter their usernames and passwords. Only the Android version of Spotify was affected by the hack. Stal said that this time iPhone and Windows phone users don't have to do anything but said Android users should upgrade their app in the next few days.
