Utility Trailer Manufacturing, one of the largest U.S. producers of trailers for the trucking industry, was targeted in an apparent ransomware attack that exposed personal information of numerous employees.
The California-based company told FreightWaves that it had “suffered a cyber event” that disrupted some systems temporarily. The company disclosed the incident after the Clop ransomware gang leaked over 5 gigabytes of data to the dark web this week.
“Upon discovery, Utility immediately responded to secure its systems and commenced an investigation into the nature and scope of the event,” Utility said in a statement. “Utility is working around the clock with assistance from third-party forensic computer specialists to investigate the full nature and scope of the attack and to bring the offline systems back online safely and securely.”
Utility did not not address the scope of the cyberattack, including when it occurred and and whether it has impacted operations. The company also did not disclose the extent of the data compromised.
The data reviewed by FreightWaves, which isn’t accessible via standard web browsers, includes an extensive amount of sensitive personal data about employees, including payrolls and human resources information.
“Utility treats its responsibility to safeguard client, customer and employee information and data as an utmost priority,” the company said.
Ransomware gang’s victims include rail operator CSX
Ransomware gangs like Clop typically begin leaking data after victims refuse to pay them. The group blamed for the Colonial Pipeline attack, DarkSide, uses the same tactic.
Clop has hit multiple major companies, including rail operator CSX and the Canadian fuel distributor Parkland.
Utility is the third-largest trailer producer in the United States, according to Trailer Body Builder. The company says it is the single largest manufacturer of refrigerated trailers.
Headquartered in the City of Industry, Utility operates five factories in the U.S.
