Bank

A bank experienced a triple extortion ransomware attack where attackers not only encrypted systems and stole sensitive data but also followed up with DDoS attacks and contacted the bank's customers to pressure the bank into paying the ransom. The attackers threatened to expose sensitive customer information and confidential deal documents, posing a significant reputational and legal risk. The situation escalated when the stolen data appeared on dark web leak sites, adding external scrutiny and pressure. The attackers weaponized the short disclosure timelines to their advantage, making it a race against time for the bank.
