Hackers who stole information on thousands of Canadian bank users have demanded $1 million-worth of the cryptocurrency XRP to not release the data trove.

According to a CBC News report Tuesday, the two banks hit by the breach, Bank of Montreal and CIBC's online bank Simplii Financial, have said that the personal information of a total of 90,000 account holders had been taken – including identifying data such as names, account numbers, passwords.
