Liability for damages from impersonation emails

It's the same as not having antivirus software installed! The impersonated party will bear liability for damages.

The liability for damages caused by impersonation emails may fall on the "impersonated party." If it is deemed that necessary measures have not been taken, such as not having antivirus software installed, the impersonated company may be held liable for damages based on tort law (Civil Code Article 709). Additionally, the directors of the company may be held liable for damages to the company due to violations of their duty to establish an internal control system.
