In modern ransomware campaigns, threat actors often employ double extortion tactics. This method involves not only encrypting an organization's data to disrupt operations but also stealing sensitive information to use as leverage. If the threat actor employs these tactics, it may exert pressure on the organization's operational continuity. In such scenarios, organizations typically focus on robust backup strategies, continuous monitoring, and comprehensive incident response plans to mitigate the impact of both data theft and service disruption.
