In this scenario, attackers do not just encrypt an organization's data to disrupt operations; they also steal sensitive information. The threat of leaking this stolen data on a public platform is used as leverage to coerce the victim into paying a ransom. If the victim refuses to pay, the group threatens to release the data to the public, causing significant reputational and legal consequences.
