Yandex said in a statement in response to the media that their systems were not hacked and that a former employee leaked the source code repository. No threats to user data or platform performance have been identified so far.

But security researchers said it was only a matter of time before Yandex’s leaked code made it possible for hackers to identify security flaws and create targeted exploits.
