Spotify users may want to consider changing their passwords. A post on the Spotify blog titled “Important Notice to Our Users” makes it clear that Spotify has had some “unauthorized access” to their systems and internal company data. Another way to phrase that would be to say that Spotify has been hacked.
The blog contains some details about what happened and gives advice to Spotify users. In their blog, they note that their evidence shows that only one Spotify user’s data has been accessed, and that this did not include any password, financial or payment information. (They also mention that they have notified that one, unfortunate, user).
As a “general precaution”, Spotify will be asking certain Spotify users to re-enter their username and password to log in “over the coming days”. In addition, they are going to guide Android users to upgrade over the next few days. Spotify also points out that offline playlists will have to be re-downloaded in the new version. There is no action recommended for iOS or Windows Phone users.
