Over 100 million Russian social network vk.com users’ data is being offered for sale on the darkweb by a seller who goes by the name Tessa88@exploit.im. Each record is expected to contain an email address, first and last name, a location, phone number and clear text password.
It is apparent that the social network stored the passwords in plaintext, Helpnetsecurity noted. According to Helpnetsecurity, the most used passwords in the list were ‘123456’ followed by ‘123456789’, then ‘qwerty’ and a host of other very common and predictable passwords.
VK users can check the Leaked Source database to know if their account is among the stolen data.
