Hackers who have access to customer dataCanadian cryptocurrency exchange CoinSquare, promised to crack it with the substitution of SIM-cards. A statement by one of the attackers was published by Motherboard. Last year, a data leak occurred on the trading floor. After that, the company changed its data management system and strengthened internal control measures.

Then it turned out that the leak could bemuch larger. The company denies security concerns. Hackers planned to sell the data of exchange customers on a darknet, but later announced their intention to use it to steal cryptocurrency from users' wallets.

“We will dishonor a company that called itself the most secure exchange in Canada, but lied,” one of the hackers said.

He also gave Motherboard part of the database,containing over 5000 addresses and e-mails of users, phone numbers, in some cases physical addresses and information on the volume of assets credited to exchange accounts for six months. Passwords are not listed, but the publication found that CoinSquare accounts were actually registered at the specified email addresses.
