Mobile web browser Opera has said that it’s Opera Sync servers, where users synchronised passwords and account information are stored, was breached on Friday.
The Sync service allows users to synchronise their Opera web browser settings and data across various devices.
There are 1.7 million active users of Opera sync, which is less than 0.5 percent of the total Opera user base of 350 million people, the company claims.
The Norwegian company, in its blog post, stated that they have reset all the Opera sync account passwords as a precautionary measure.
“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,” the statement read.
“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,” it added.
The mobile web browser company has asked its users, who do not use Opera sync, not to fret about the incident.
The news of security breach also comes a month after a Chinese consortium, led by search and security firm Qihoo 360, acquired Opera for 600 million dollars (approx. Rs. 4025 crores).
