Amazon-owned game streaming service Twitch was hacked, the company announced in a blog post Monday. The attackers gained access to users' account information.



Users will be notified that their passwords have been reset the next time they log in

he company also sent an email to users, warning that their account information may have been compromised, including email addresses, passwords (cryptographically protected, according to Twitch), IP addresses and limited credit card information. Full credit card numbers aren't stored by Twitch, but other personal data is, such as card type, truncated card number and expiration date.

"We are writing to let you know that there may have been unauthorized 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," Twitch's blog post read.

Users will be notified that their passwords have been reset the next time they log in, and will be prompted to choose a new password. Furthermore, those who connected their Twitter, YouTube or Facebook accounts with Twitch will have to reconnect those accounts to the service again.

Twitch provided no further information about the nature of the attack or the measures it is undertaking to identify the hackers. Representatives for Twitch didn't immediately respond to a request for comment.
Twitch, which lets users watch other people play games, was acquired by Amazon for $970 million in August 2014. In January of this year, the company launched a music library, as well as music as an entirely new category.
