Music streaming service Spotify will ask some of its 40 million users to re-enter their passwords and upgrade their software in coming days after detecting unauthorised access to its internal systems and data.
Chief technology officer Oskar Stal said in a blog post on Tuesday that Spotify had found evidence of attackers accessing just one user's data, which did not include payment or password information.
But as a precaution, it intends to ask "certain Spotify users" to re-enter their log-in credentials, and upgrade their Google Android app.
Spotify said it is not recommending any action yet for users of Apple iPhones or devices based on Microsoft's Windows.
The intrusion was the latest to hit a major tech company. In past months, cyber attackers have infiltrated databases and systems at eBay and Adobe, though no financial information has so far been taken, according to the companies.
Spotify, which is expected to seek an IPO soon, has more than 40 million active users scattered across more than 50 markets.
"We have taken steps to strengthen our security systems in general and help protect you and your data – and we will continue to do so. We will be taking further actions in the coming days to increase security for our users," Stal said in his blog post.
