Short take:

A breach of some type appears to have occurred; however, details are scant at this point.

Excerpt:

Two of Canada’s biggest banks are warning that “fraudsters” may have accessed certain personal and financial information from some customers.

The Bank of Montreal says that fraudsters contacted the bank on Sunday claiming to be in possession of certain data for a “limited number of customers” and it believes the attack was originated outside of Canada.

BMO says it took immediate steps after learning of the potential breach and is confident that exposures related to customer data have been “closed off.”
