Sierra Wireless, a leading IoT solutions provider, announced that it halted production after facing a ransomware attack on its internal IT systems on March 20, 2021.
Sierra Wireless informed that its IT and operations teams have implemented measures to counter the attack. These teams, with the assistance of third-party advisors, believe they have addressed the attack, and are currently working to bring Sierra Wireless’ internal IT systems back online.
Sierra Wireless did not reveal additional details about the cyber security incident and the impact on its business. The Canadian multinational headquartered in Richmond, British Columbia, has more than 1,300 employees worldwide, develops communication equipment, and has research and development centers in North America, Europe, and Asia.
At this time, Sierra Wireless believes the impact of the attack was limited to Sierra Wireless systems, as the company maintains a clear separation between its internal IT systems and customer facing products and services.
Sierra Wireless halted production at its manufacturing sites as a result of the ransomware attack. The company’s website and other internal operations have also been disrupted by the attack. The company will restart production at these facilities and resume normal operations soon.
Sierra Wireless is withdrawing revenue guidance of $109.9 million during the first quarter 2021 guidance it provided on February 23, 2021.
Revenue of Sierra Wireless decreased 18 percent to $448.6 million in 2020 due to Covid-19 pandemic, lower mobile computing module sales from design losses, and tight component supply primarily in the late third and fourth quarter of 2020.
