2022 Bridgestone Americas — ransomware; production disruption across North American plants (Feb–Mar)
Data compromised
Corporate operational data; potential HR/partner material in actor-marketing claims—no single authoritative headcount in first-party summaries reviewed for this row
Technical writeup
Bridgestone Corporation and Bridgestone Americas publicly acknowledged a ransomware intrusion detected February 27, 2022, that disrupted IT and manufacturing operations, including temporary shutdowns at multiple North American tire plants. Reuters and follow-on trade coverage summarized law-enforcement engagement and recovery work. Later reporting tied LockBit marketing/extortion claims to the same incident window; Bridgestone’s initial releases emphasized operational disruption more than standardized PII counts.
