Lockbit Attacks US Networks of Largest Zipper Manufacturer in Japan

October 2, 2023


Japanese zipper giant YKK confirmed that its U.S. operations were targeted by hackers in recent weeks but said it was able to contain the threat before damage was caused. The Tokyo-based corporation would not say if it was hit with ransomware, but a spokesperson told Recorded Future News that once YKK discovered that its U.S.-based networks were targeted, the cybersecurity team “contained the threat before significant damage was done or sensitive information was exfiltrated.”

“The incident did not have a material impact on our operations or our ability to continue to serve our customers,” said Jessica Kennett Cork, vice president of corporate communications at YKK Corporation of America.
