Passport numbers compromised in Air Canada data breach

Air Canada is warning users who entered their passport information into the airline's app that users' passport numbers may have been stolen after a data breach caused the loss of customers' personal information, the BBC reports.

Why it matters: If passport numbers were stolen from the app, thousands of customers could be at risk for ID fraud. The airline has previously been criticized for weak password security measures, according to the BBC, and this breach may have been a result of that.
