Incident analysis

Toyota was listed by Byod ransomware, a group with 25 victims recorded in this database. The listing appeared on the group's leak site on November 10, 2026.

Toyota is based in Japan and operates in the Manufacturing sector. Japan ranks #12 worldwide for ransomware disclosures, with 310 victims in this database.

Sector context. Manufacturing companies are frequently targeted because production downtime directly translates to financial loss. Ransomware operators exploit this time-sensitivity to demand higher ransoms and faster payment.

Byod typically follows a double extortion model: data is exfiltrated from the victim's systems before files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished. The leak site, where this listing appeared, is the lever for the second demand.

Source. Public leak-site disclosures aggregated via the ransomware.live API. The disclosure date is when the listing was published, which can differ from the date of compromise. This site does not publish or link to stolen data. Last updated .

Which ransomware group attacked Toyota?

Toyota was attacked by Byod ransomware. Byod is one of the most active ransomware groups, having claimed 25 victims globally. The group typically employs a double-extortion model: encrypting the victim's files and threatening to publish stolen data.

What data was stolen in the Toyota ransomware attack?

The specific data stolen from Toyota has not been independently verified by this platform. Ransomware groups typically exfiltrate data before encrypting systems and use the threat of publication to pressure victims. As a Manufacturing organisation, Toyota likely held sensitive business data, client information, and operational records.

How can organisations protect against Byod attacks?

To defend against Byod and similar threat actors, organisations should: maintain regular offline backups tested for restoration; implement network segmentation to limit lateral movement; deploy multi-factor authentication on all remote access; use endpoint detection and response (EDR) tools; conduct regular phishing and security awareness training; and monitor threat intelligence feeds for indicators of compromise (IOCs) associated with active groups.
