2025: Cyberattack that disrupted airline operations
In mid-June 2025, Canada's second largest airline, WestJet, reported a hacker attack on its IT infrastructure. As a result of cyber intrusion, the operation of the internal systems and mobile application of the air carrier was disrupted.
The official notification says that due to the attack, some users lost access to the airline's services. WestJet activated internal safety protocols and also notified law enforcement and Transport Canada of the incident. Experts are investigating what happened and minimizing possible consequences.

A WestJet spokesperson told NBC News that the company first detected signs of a breach on June 13, 2025, immediately after which it took the necessary security measures. As of the end of that month, the carrier had made "significant progress" in addressing the issue. Whether any confidential information was stolen as a result of the invasion is not specified. It is also not clear whether WestJet's malfunctions are related to the introduction of ransomware or other type of malware. Company spokesman Josh Yeats said the investigation into the incident is ongoing in conjunction with law enforcement. The WestJet website also says that "third-party world-class experts" on cybersecurity and forensic experts are involved in establishing the causes of the incident.[1]
