In 2013, Target experienced a severe cyber attack that exposed the payment card information of 41 million customers and the contact information for approximately 70 million customers. The breach was orchestrated via a spear phishing attack aimed at a third-party vendor, which allowed the attackers to compromise Target's network and install malware. This malware was then used to capture customer data over two months. The financial repercussions of the attack were substantial, with the overall cost to Target being approximately $290 million. This included fines, remediation efforts, consulting fees, and other various expenses. The breach not only resulted in significant financial losses but also led to the departure of Target's CEO and harmed the company's reputation among consumers.
