Russian tech giant Yandex’s data harvesting raises security concerns

Russia’s biggest internet company has embedded code into apps found on mobile devices that allows information about millions of users to be sent to servers located in its home country.

The revelation relates to software created by Yandex that permits developers to create apps for devices running Apple’s iOS and Google’s Android, systems that run the vast majority of the world’s smartphones.

Yandex collects user data harvested from mobiles, before sending the information to servers in Russia. Researchers have raised concerns the same “metadata” may then be accessed by the Kremlin and used to track people through their mobiles.

Researcher Zach Edwards first made the discovery regarding Yandex’s code as part of an app auditing campaign for Me2B Alliance, a non-profit. Four independent experts ran tests for the Financial Times to verify his work.

Yandex has acknowledged its software collects “device, network and IP address” information that is stored “both in Finland and in Russia”, but it called this data “non-personalised and very limited”. It added: “Although theoretically possible, in practice it is extremely hard to identify users based solely on such information collected. Yandex definitely cannot do this.”

The company said it followed “a very strict” internal process when dealing with governments: “Any requests that fail to comply with all relevant procedural and legal requirements are turned down.”

But Cher Scarlett, formerly a principal software engineer in global security at Apple, said once user information was collected on Russian servers, Yandex could be obliged to submit it to the government under local laws. Other experts said that the metadata of the sort…
