In March 2023, Hypothetical Corp suffered a severe data breach incident resulting from a sophisticated ransomware attack. Cybercriminals exploited a previously unknown vulnerability in the company's email system, gaining unauthorized access to the financial and personal information of over 10,000 customers. The breach was first detected by the company's internal security team, who noticed unusual activity on their network over a weekend. Despite efforts to contain the attack, sensitive data was exfiltrated, leading to significant financial and reputational damage. The company had to halt operations temporarily to address the security flaw, and the incident has led to an ongoing investigation by regulatory authorities.
