6.5 terabytes of searches and other information entered via the smartphone app of search engine Bing, appears to have been on a leaky server for days, writes cybersecurity researcher WizCase Tuesday.

The data was on an unsecured Elastic server.

WizCase found, among other things, searches, location data and information about which websites were visited.

The type of device and the individual ID code of the user could also be found.

According to WizCase, the server contained data from at least seventy countries.

The company found the server two days after the password was removed.

The server has been attacked several times by hackers.

WizCase reported the leak to Microsoft, which was able to close it a few days later.
