Proposed class-action lawsuits filed against BMO, CIBC's Simplii after possible data breaches
Simplii and BMO warned in May that 'fraudsters' may have accessed certain personal and financial information
Proposed class-action lawsuits have been filed against Bank of Montreal and CIBC's direct banking division Simplii Financial over recently disclosed cybersecurity breaches impacting up to 90,000 customers.
The banks did not immediately respond to requests for comment. Simplii and BMO warned in May that "fraudsters" may have accessed certain personal and financial information of some of its customers, up to 40,000 clients and 50,000 clients, respectively.
A BMO spokesman said a threat was made to make the information public.
BMO and CIBC have since offered clients free credit monitoring and have pledged to cover any money lost from affected bank accounts due to fraud.
