On July 4, Yandex users paid attention to the beginning of indexing by the search engine of documents Google Docs, where there was personal information (corporate information, information about passwords and credit card data). The problem was quickly resolved, and already at 1 am on Thursday, the information again became inaccessible to ordinary users.
Why did this happen?
Formally, the search engine refers to the incorrect settings of privacy by the users themselves, but it is unlikely that the owners of such documents have discovered random access to valuable personal information and sent someone a link.
Among the experts, there is an opinion that the reason for the information coming out could be the use of Yandex.Browser or the forwarding of links through the mail of the largest Russian search engine, which were automatically indexed, and information accidentally fell into the general access. In any case, in 2015 it turned out that the proprietary browser automatically transmitted information about the visited pages to the Yandex server. The latter were included in the database of the search robot, which was able to enter into separate user profiles without entering a password. Then the management of Yandex reported that such a practice would be terminated.
What should the user do?
Short-term entry into the search engines of private information can potentially threaten legal and natural persons because of the opportunity to use it for personal gain. This in an interview with "360" said one of the heads of advertising agencies, which in Google Docs stores all important information.
For our part, we recommend that users refuse to store valuable information on the Internet on cloud services and, in a mandatory manner, additionally control the privacy settings.
