Multiple sales subsidiaries of Toyota Motor Corp. were breached in an apparent cyberattack that may have leaked the personal information of up to 3.1 million people in the Tokyo area.
Toyota announced the possible breach as being the result of “unauthorized access” to a network server containing customer information in late March, but explained that they were unable to confirm if any data was actually lost.
The hacking attempt was followed the next day by similar cyberattacks on Toyota’s subsidiaries in Vietnam and Thailand, each of which issued statements about the possibility of breaches without any further details or confirmation regarding the data compromised.
These three attempts followed another announcement made by Toyota’s Australian subsidiary in February, where it disclosed an attempted hack but was similarly light on details.
Toyota has yet to issue further statements on these incidents, but has apologized and promised to implement stronger security measures on their networks and at their facilities.
