U.S. truck maker Navistar disclosed that the company had fallen victim to a cyber security attack.

On Monday, June 7, Navistar disclosed that the company “learned of a credible potential cybersecurity threat to its information technology system (“IT System”) on May 20, 2021.

In a filing with the United States Securities and Exchange Commission, Navistar said the company launched an investigation and undertook immediate action to respond to the attack, engaging internal and external experts to help respond.

Navistar says that the company’s systems remain fully operational.

The company says that on May 31, 2021, they received a claim that “certain data” had been extracted from IT systems.

Navistar says that they are working with law enforcement and third-party cyber security experts to address the threat.

Navistar is not the only company to fall victim to cyber attacks in recent weeks. A May attack on the Colonial Pipeline impacted the fuel supply chain and prompted the Federal Motor Carrier Safety Administration (FMCSA) to issue an emergency declaration for truckers hauling fuel. JBS, one of the world’s largest meat producers, also recently fell victim to cyber attack.
