As announced on March 23th and updated on March 26th, Canada-based IoT company Sierra Wireless became a victim of a ransomware attack on its internal IT systems and corporate website, and temporarily closed down production at its manufacturing sites.

Sierra Wireless is the leading IoT solutions provider that combines devices, network services, and software to unlock value in the connected economy. Their products are used worldwide in industrial and enterprise settings, including in the commercial facilities, communications, government, energy, transportation, and water sectors.

The company thinks the ransomware attack has only affected its own systems, indicating that it “maintains a clear separation between its internal IT systems and customer-facing products and services.”

“At this point in its investigation of the ransomware attack, the company does not expect there to be any product security patches, or firmware or software updates required as a result of the attack,” the company said in a statement.


As soon as the company learned of the attack, its IT and operations teams instantly implemented measures to encounter the attack.

The IoT company Sierra Wireless has been collaborating with Blake, Cassels and Graydon LLP, one of the leading cybersecurity law firms, as breach coach and legal counsel, and KPMG, one of the world’s leading forensic investigation and cyber incident response firms, in response to the ransomware attack, and to investigate what happened.

“Security is a top priority, and Sierra Wireless is committed to taking all appropriate measures to ensure the highest integrity of all of our systems.

I’m proud of the efforts of our IT team and external advisors as they have mitigated the attack and made real progress in getting operations up and running,” said Sam Cochrane, CFO at Sierra Wireless.


Fortunately, the company declared last Friday that it has restored production at its manufacturing sites and is working towards restoring internal networks.

We still don’t know when the remaining systems hit by the ransomware attack will be fixed, what form of ransomware encrypted the network, or how Sierra Wireless ended up falling victim to the cyberattack.

Sierra Wireless’s team, with the assistance of additional third-party advisors, continues to investigate the incident and the extent of the impact on the company’s internal IT systems.
