Mitsubishi data breach caused by remote working malware


Mitsubishi data breach was caused by remote working malware.

Mitsubishi has announced that its group network, used by employees whilst working from home, was accessed by unauthorised third-party malware using malicious social engineering techniques.

The Mitsubishi data breach, which occurred in May 2020, occurred when an employee downloaded the malware, which resulted in the leakage of primarily IT-related data as well as the names and emails of employees using the group network.

Moreover, Mitsubishi confirmed that, following the investigation, it had issued company-wide warnings and implemented countermeasures such as the use of VPNs through internal networks, and new password requirements for administrator accounts on the network.


This shows that at most businesses security is only as strong as its weakest link and that its weakest are often its workers. In these difficult times, with homeworking commonplace and likely to remain for the foreseeable future, it’s essential to educate workers about the risks accidentally downloading malware.

Appointing NormCyber as our virtual DPO has given Ferrero the best of both worlds – access to data protection experts who understand what we stand for as a business, without the hefty overheads usually associated with appointing an in-house DPO.

The speed of your Data Protection Officer’s response was very impressive – it was far quicker than I would have expected even from an in-house DPO
