Target

In 2013, Target suffered a considerable cybersecurity breach that exposed 41 million payment cards and the contact information of approximately 70 million customers. Using a spear phishing attack on a third-party vendor to harvest user credentials, attackers accessed Target's network and installed malware to capture customer data over two months. This breach significantly impacted Target, leading to the CEO's departure and costs approximating $290 million when considering fines, remediation, consulting fees, and other related expenses. The breach underscored the vital importance of robust cybersecurity measures and the complexities involved in protecting customer data, especially for large retail organizations.
