The potential publication of stolen data creates various secondary risks. These include the possibility of identity theft or the execution of targeted phishing attacks directed at the company's employees and customers. In such scenarios, threat actors often use stolen information to conduct social engineering attacks, where they pose as legitimate entities to deceive individuals into revealing further sensitive information.

For organizations operating within the professional services and retail sectors, such threats highlight the importance of robust cybersecurity postures. Common defensive strategies often include implementing multi-factor authentication, maintaining rigorous patch management schedules, and conducting regular security awareness training for staff to recognize phishing attempts. Furthermore, maintaining comprehensive incident response plans and ensuring regular, encrypted backups are essential components of a modern defense-in-depth strategy to mitigate the impact of potential exfiltration events.
