Live-streaming video game service Twitch has announced in a blog post that its website has been compromised in a cyber attack resulting in the leak of user information.
The company which was purchased by Amazon for $970m in August last year, emailed those it deemed affected by the hack telling them their password, email address, user name, home address, phone number and date of birth may have been stolen.
The company said: "We are writing to let you know that there may have been unauthorised access to some Twitch user account information.
"For your protection, we have expired passwords and stream keys and have disconnected accounts from Twitter and YouTube. As a result, you will be prompted to create a new password the next time you attempt to log into your Twitch account.
"We also recommend that you change your password at any website where you use the same or a similar password. We will communicate directly with affected users with additional details."
Twitch boasts 100m monthly active users on the website.
