UniCredit SpA said hackers accessed about 400,000 client bank accounts in Italy, taking biographical and loan data in one of the biggest breaches in Europe to date. 

The breaches occurred in September and October of 2016 and June to July of this year, the bank said on Wednesday in an emailed statement. Unauthorised access through an Italian third party provider gave access to some customer data related to personal loans, with the lender saying IBAN numbers and other personal data may also have been accessed.
