Fast Facts

• WestJet confirmed a data breach affecting 1.2 million customers.
• Exposed data includes names, birthdates, addresses, and travel documents like passports.
• Attackers accessed systems via social engineering and a Citrix login reset.
• No credit card numbers or passwords were compromised, but loyalty card info was.
• The FBI is investigating; impacted customers are offered two years of free identity monitoring.

A Breach at 30,000 Feet

Picture the digital cockpit of a major airline: blinking lights, data streams, and the sensitive information of millions of travelers soaring through cyberspace. In June 2024, WestJet - one of North America’s busiest airlines - found its digital controls hijacked. The breach, now confirmed to have exposed the personal details of 1.2 million customers, has sent turbulence through the aviation and cybersecurity worlds.

The Anatomy of the Hack

On June 13, WestJet revealed a cyber incident that grounded its app and disrupted internal systems. Behind the scenes, hackers allegedly used social engineering - a form of trickery where someone is manipulated into giving up access - to reset an employee’s password. This gave the attackers a foothold via Citrix, a widely used remote access tool, and let them slip past the airline’s digital defenses.

Once inside, the hackers gained access to both Windows-based internal networks and the company’s Microsoft cloud environment. This two-pronged attack allowed them to hunt for and exfiltrate sensitive customer data, ranging from full names and birthdates to passport numbers and travel preferences. While the attackers didn’t get their hands on payment card numbers or login passwords, they did walk away with loyalty program details and even some filed complaints - potentially useful for further social engineering schemes.

Industry Pattern: Aviation Under Attack

The WestJet breach is part of a broader trend: airlines and travel companies have become prime targets for cybercriminals. In recent years, similar attacks have hit British Airways, Cathay Pacific, and Air India, often exposing millions of passenger records. Groups like Scattered Spider, known for targeting large organizations through clever manipulation rather than brute-force hacking, have turned their attention to the aviation sector - though no official attribution has been made in WestJet’s case.

Why airlines? The answer is twofold: they hold a goldmine of personal information, and their complex, interconnected systems can be hard to secure. With global travel rebounding post-pandemic, the value of stolen travel documents and IDs on underground markets has soared, feeding identity theft rings and fraudsters worldwide.

Aftermath and Looking Forward

WestJet has notified affected customers and is working with the FBI and cybersecurity experts to contain the fallout. The airline is offering two years of free identity theft monitoring - a standard gesture after such breaches, but one that underscores the enduring risks. As digital transformation accelerates in aviation, this breach serves as a stark warning: even as we fly higher, our data remains vulnerable on the ground.

For travelers, the lesson is clear: your boarding pass is no longer the only ticket worth guarding.

• Social Engineering: Social engineering is the use of deception by hackers to trick people into revealing confidential information or providing unauthorized system access.
• Citrix: Citrix is a platform that allows employees to securely access company networks and applications remotely, supporting flexible work while requiring strong security.
• Data Breach: A data breach is when unauthorized parties access or steal private data from an organization, often leading to exposure of sensitive or confidential information.
• Exfiltration: Exfiltration is the unauthorized transfer of sensitive data from a victim’s network to an external system controlled by attackers.
• Identity Theft Monitoring: Identity theft monitoring alerts you if your personal information is misused, helping you detect and respond quickly to potential identity theft.
