Canadian IoT solutions provider Sierra Wireless revealed it has suffered a ransomware attack against its internal IT systems that has led to production being halted on its manufacturing sites.
In a SEC filing the IoT devices maker said that the incident took place on March 20, 2021.
“Once the company learned of the attack, its IT and operations teams immediately implemented measures to counter the attack in accordance with established cybersecurity procedures and policies that were developed in collaboration with third-party advisors. These teams, with the assistance of these and additional third-party advisors, believe they have addressed the attack, and are currently working to bring Sierra Wireless’ internal IT systems back online,” the company said.
The attack has also disrupted the company’s website and other internal operations. The incident has also led to withdrawal of Sierra Wireless’ First Quarter 2021 guidance it provided on February 23, 2021.
Sierra Wireless believes that the attack has only affected its own systems, “as the company maintains a clear separation between its internal IT systems and customer facing products and services.”
It's currently unclear when production facilities and other systems will return to normal, but Sierra Wireless believes it will resume operations "soon."
