Bombardier Statement on Cybersecurity Breach

Bombardier (TSX: BBD.B) announced today that it recently suffered a limited cybersecurity breach. An initial investigation revealed that an unauthorized party accessed and extracted data by exploiting a vulnerability affecting a third-party file-transfer application, which was running on purpose-built servers isolated from the main Bombardier IT network.

In accordance with established cybersecurity procedures and policies, Bombardier promptly initiated its response protocol upon detection of the data security incident. As part of its investigation, Bombardier sought the services of cybersecurity and forensic professionals who provided external confirmation that the company’s security controls were effective in limiting the scope and extent of the incident. Bombardier also notified appropriate authorities, including law enforcement, where required and will continue to work with the authorities as the investigation continues.

Forensic analysis revealed that personal and other confidential information relating to employees, customers and suppliers was compromised. Approximately 130 employees located in Costa Rica were impacted. Bombardier has been proactively contacting customers and other external stakeholders whose data was potentially compromised. The ongoing investigation indicates that the unauthorized access was limited solely to data stored on the specific servers. Manufacturing and customer support operations have not been impacted or interrupted. Bombardier can also confirm the company was not specifically targeted—the vulnerability impacted multiple organizations using the application. Bombardier will continue to assess the situation and stay in close contact with its clients, suppliers and employees, as well as other stakeholders.

With the ever-increasing number and sophistication of cybersecurity attacks on corporate groups, Bombardier remains committed to maintaining the integrity of its IT infrastructure and safeguarding employee, client and supplier information.
