Earlier this week, we detected signs of an attack where access was gained to the Opera sync system. This attack was quickly blocked. Our investigations are ongoing, but we believe some data, including some of our sync users’ passwords and account information, such as login names, may have been compromised.

Although we only store encrypted (for synchronized passwords) or hashed and salted (for authentication) passwords in this system, we have reset all the Opera sync account passwords as a precaution.

We have also sent emails to all Opera sync users to inform them about the incident and ask them to change the password for their Opera sync accounts. In an abundance of caution, we have encouraged users to also reset any passwords to third party sites they may have synchronized with the service.

To obtain a new password for Opera sync, use the password resetting page.

The total active number of users of Opera sync in the last month is 1.7 million, less than 0.5% of the total Opera user base of 350 million people.

The remaining Opera browser users who do not use Opera sync, do not need to take any actions.

We take your data security very seriously, and want to sincerely apologize for the inconvenience this might have caused.

本周早些时候，我们检测到攻击的迹象，在那里获得了获得了歌剧院同步系统。这种攻击被迅速封锁。我们的调查正在进行中，但我们相信一些数据，包括我们一些同步用户的密码和帐户信息，如登录名，可能已被泄露。

虽然我们只存储加密的（用于同步的密码）或哈希和盐渍（认证），在这个系统中的密码，我们已经重置所有歌剧同步帐户密码作为一项预防措施。

我们还发送的电子邮件到所有歌剧同步用户向他们通报这一事件，并要求他们为自己的歌剧同步帐户更改密码。在慎重起见，我们鼓励用户也恢复到第三方网站，他们可能与服务同步的任何密码。

要获得歌剧同步一个新的密码，使用密码重置页面。

在上个月歌剧院同步用户的总人数主动为1.7亿，3.5亿人的总Opera的用户群小于0.5％。

谁不使用Opera同步剩下的Opera浏览器的用户，不需要采取任何行动。

我们把你的数据安全性非常重视，并要真诚地为这可能造成的不便表示歉意。
