The company said Friday that “member profile data” has been accessed, but stressed no credit card, banking information, travel documentation or travel history information was part of the breach. However, WestJet isn’t saying how many reward card members affected or what information was stolen.
Profile information could include names, home or business addresses, email addresses and phone numbers, some of which could be used to create phony identification.
“This type of ID data can be used by cybercriminals as part of their social engineering and phishing campaigns,” said Forrester Research security analyst Joseph Blankenship.
“For example, cyberthieves may be able to pose as agents of a breached company and attempt to get targeted consumers to reveal login information such as their user name and password or have them click on a link to a malicious website. Attackers could also call victims using similar tactics to get the victim to give up sensitive information like passwords or credit card numbers. This is especially worrisome since so many people reuse passwords across multiple websites.”
In its statement WestJet said it has taken immediate steps to secure affected systems and has been working closely with the Calgary Police Service and the RCMP cybercrime unit in its investigation. The Office of the Information and Privacy Commissioner of Alberta and the federal Privacy Commissioner has been informed.
“The privacy and protection of our guests’ information is a matter we take very seriously and we have worked swiftly and aggressively to resolve this incident,” Craig Maccubbin, WestJet’s executive vice-president and CIO, said in the statement. “WestJet is in the process of contacting affected guests and we deeply regret any inconvenience this may cause.”
The airline also asked all WestJet Rewards members to regularly update their passwords.
Today WestJet declined a request for an interview. Instead spokesperson Lauren Stewart said in an email that the incident was discovered after the airline received an email on the afternoon of July 27 that appeared to be spam. It became aware of the disclosure of certain information the next day.
