📝 Description
The Qilin ransomware group has claimed responsibility for an attack on Hikari Seiko Co. Ltd., a major Japanese manufacturer of universal joints and precision automotive components.

According to the group’s statement, they exfiltrated 502.5 GB of data before encrypting Hikari Seiko’s network. The ransom note suggests that negotiations with the company were ignored, leading to the full leak of corporate data.

The compromised files reportedly include:

• Emails and internal reports
• Maintenance and engineering data
• Limited access product drawings
• Production improvement documentation
• Cost reduction and labor cost records
• Customer data related to major clients (BYD, Ford, Honda, Zeekr, etc.)
• Employee database backup

Sample images of leaked documents (email directories, CAD drawings, financial spreadsheets) were posted on the Qilin ransomware leak site as proof of compromise.
