Navistar International Corporation, a manufacturer of trucks and military vehicles in the United States, has disclosed a cyberattack in which some data was stolen.
Navistar claimed it learned of a credible possible cybersecurity vulnerability to its information technology system on May 20, 2021, in a Form 8-K statement with the Securities and Exchange Commission (SEC).
Navistar acted quickly to control and limit the incident’s impact, as well as initiate an inquiry into the situation, enlisting the help of security and forensics professionals.
The corporation also made steps to improve the security of its IT infrastructure and preserve the data it houses, claiming that all of its systems have remained operational.
Navistar, on the other hand, “received a claim that certain data had been stolen from” its network on May 31.
The corporation is still looking into “the scope and effects of the cybersecurity incident” and has already alerted law police about it.
Navistar did not share technical information about the event, but given the increased number of ransomware cases in recent months in which attackers seized victim data to use as leverage, it’s possible that ransomware was involved.
Navistar, founded in 1986, manufactures trucks, buses, and diesel engines, as well as military vehicles through its Navistar Defense division.
Following a ransomware attack that prompted Colonial Pipeline to shut down distribution networks in early May, JBS USA, the US division of the world’s largest meat processing corporation, revealed last week that it had also halted operations in the United States and Australia.
A similar attack was also launched last week on Steamship Authority, the largest ferry service between Cape Cod and the Massachusetts Islands of Martha’s Vineyard and Nantucket. Molson Coors Beverage Company was hit by malware earlier this year.
