TORONTO (Reuters) - BCE Inc, Canada's largest telecom company, said 22,421 small business customers' user names and passwords were posted online over the weekend after an unnamed third-party supplier was hacked.
Five valid credit card numbers were also posted, BCE's Bell Canada unit said in a release on Sunday. It said its own systems were not affected.
The company said it had disabled the passwords and informed credit card companies, and it was contacting affected customers.
