The threat actor listed Shimano on its leak site, saying it had stolen roughly 4.5 terabytes of sensitive data, affecting both customers and employees.

The data included residential addresses, telephone numbers, bank statements, financial documents, confidential documents and contracts, just to name a few.

LockBit gave Shimano a 5 November deadline to pay ransom, to which it appears Shimano refused to pay, as the hacking group has listed the company’s data as published.

“All available data published!” the group said. That being said, no data is visible or accessible on the leak site.

Shimano is yet to issue a statement on the breach, but responding to media inquiries, the company said: “This is an internal matter at Shimano, and we cannot comment on anything at this time.”

Cyber Daily has reached out to Shimano requesting additional information on the nature of the breach.

LockBit is arguably the biggest ransomware group in the world. In May 2022, it was responsible for 40 per cent of all ransomware attacks.

Most recently, the group launched an attack on Boeing, claiming it had stolen a large amount of data. As Boeing said it was assessing the validity of the claim, the threat actor delisted the company from its leak site.

While neither party has said why this has happened, this could mean a number of things, such as that ransom negotiations have started or have been fruitful for the hackers or that due to the sensitive and high-security nature of the information Boeing may hold, the threat actor has backed down knowing that the release of said information could land it in much hotter water than it is worth.
