Overview of the Ransomware Attack
Data from Toyota Financial Services was allegedly taken by the ‘Medusa ransomware gang’. The group offered the business ten days to provide the $8 million ransom.
The Medusa gang made claims on their leak site today, November 16, including screenshots of multiple documents confirming the hack’s authenticity and listed stolen sample data.
The files contain several spreadsheets, financial documents, staff email addresses, and scans of a Serbian passport.
One document, in particular, contains un-hashed account passwords and usernames for several types of production and development environments, and much more were all included.
The leak site features a countdown to the full data release date of November 26, which is in ten days. The gang will extend the deadline by one day for US$10,000.
The company took a few systems offline to look into this activity and lower risk. They have also started collaborating with law enforcement. They have begun getting their systems back online in the majority of countries.
German media source Heise received the Toyota data breach notification that was delivered to German customers.
Threat actors were able to obtain the following information such as:
- Full names,
- Residence addresses,
- Contract information,
- Lease-purchase details
- IBAN (International Bank Account Number)
Toyota also reported the security violation to North Rhine-Westphalia’s data protection officer.
