Compliance with these regulations is a critical aspect of managing a cybersecurity incident in the European Union.

Depending on the actual nature of the data involved, secondary risks may emerge. These include the possibility of identity theft or the execution of targeted phishing attacks against the organization's customers. Such attacks often leverage stolen personal information to deceive individuals into revealing further sensitive credentials or financial details.

Beyond the immediate technical and legal concerns, the incident may negatively impact the institution's business operations and its reputation management processes. For organizations in the retail and automotive sectors, maintaining customer trust is vital. A breach, even if unconfirmed, can necessitate significant resources to manage public perception and restore consumer confidence. Defensive measures typically involve robust incident response plans, continuous monitoring of network traffic, and strict adherence to data protection frameworks to mitigate the impact of such threats.
