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.

Security flaws let hackers hit in-flight and at sea WiFi

Multiple deployed satellite communications (SATCOM) products have security flaws, according to IOActive researcher Ruben Santamarta, who will present research in the field Wednesday at the cybersecurity conference Black Hat.

The systems are used in everything from airplane in-flight WiFi and entertainment systems to communications on ships. Santamarta found vulnerable systems in both.
