WestJet, Canada's second-largest airline, is investigating a cyberattack that has disrupted access to some internal systems and the WestJet app. The attack prevented users from logging into the website and mobile app, which have now been restored. The company has activated specialized internal teams in cooperation with law enforcement and Transport Canada to investigate the matter and limit impacts. The safety of operations and the safeguarding of sensitive data and personal information for both guests and employees are being expedited. The attack has impacted access to some of its software and services, but the company's operation continues to run safely. It is unclear if the loss of access to its systems is caused by a ransomware attack or if they shut them to prevent the spread of the breach.
