An international freight technology company said it has cut off a portion of its business in Canada after a cyberattack.

The company — Radiant Logistics — did not respond to requests for comment about whether it was dealing with a ransomware attack.

In documents filed with U.S. regulators, the company explained that on March 14 it detected “the initial stages of a cybersecurity incident related to its Canadian operations.” The company specializes in “warehouse and distribution, customs brokerage, order fulfillment, inventory management” and other services.

“Upon detection, the Company immediately initiated its incident response and business continuity protocols and began taking measures to disrupt the unauthorized activity,” the company said in its 8-K filing with the Securities and Exchange Commission. 

“As part of its process to address the incident, the Company proactively took measures to isolate its Canadian operations from the rest of its network and engaged the services of cybersecurity and forensics professionals to further assess, contain and remediate the incident.”

The incident has caused service delays for customers in Canada, but the company said the issues will be resolved over the next week. Its operations in the U.S. and internationally were not affected by the attack. 

Despite the shutdown, the filing says the incident is not “reasonably likely to materially impact the Company's financial conditions.” No ransomware gang has taken credit for the incident.

The Seattle-area company  has about $1 billion in annual revenue and provides logistics services to domestic and international freight companies, manufacturers, distributors and retailers. 

This is the second cyberattack targeting logistics software used by major trucking operations over the last six months. In September, one of the biggest providers of software for the trucking industry confirmed that a ransomware attack was impacting services.

Ransomware gangs have made a point of going after the operational networks of companies involved in critical infrastructure. Attacks on cold storage giant Americold as well as Sysco — one of the world’s largest food distributors – caused significant issues to manufacturers in 2023.
