Over a decade has passed since the significant data breach at Target Corp., which was the second largest in retail history. The breach exposed 40 million debit and credit cards and the personal information of an additional 70 million customers.
The Target data breach incident marked a critical moment for payment card security awareness. Despite being a multi-million-dollar corporation, the lessons from Target’s major security breach are valuable for all business owners. This discussion will cover the key aspects of the data breach, exploring the reasons behind it, Target’s response, and the broader lessons that can be drawn from the event.
What Transpired in the 2013 Target’s Data Breach?
In 2013, during the holiday season, the Target data breach resulted in the theft of 40 million credit and debit card details along with 70 million customer records. While not the largest breach in history, its timing and scale made it highly significant, especially following other major data breaches that had already heightened consumer anxiety.
The breach at Target underscored a critical issue: the erosion of customer trust following such incidents. Data security concerns made many customers hesitate before making further purchases from Target.
While details of the exact methods used in the Target data breach remain partially unknown, several facts provide insight into how the breach was executed. The breach began with a successful phishing attack on Fazio Mechanical Services (FMS), a third-party vendor connected to Target. Hackers installed a trojan horse on the FMS system, which had authorized access to Target’s external billing network.
This malware then spread to Target’s business network. Once in the network, the malware was installed on Target’s point-of-sale devices, enabling it to capture encrypted card information directly. The hackers then took control of three of Target’s internal servers, setting them up to collect this encrypted data, subsequently transmitted to other computers already compromised by the hackers. It is believed that the stolen credit card and customer information were later sold on the black market.
Third-party vendors often need security measures as robust as the primary business, making them vulnerable targets. This incident serves as a reminder that the security of third-party partners is crucial, as a chain is only as strong as its weakest link.
How Did the Data Breach at Target Happen?
Several missteps occurred during Target’s data breach. Firstly, the third-party vendor, FMS, lacked a robust security system, and its staff was not adequately trained to prevent and detect phishing scams. This vulnerability was a significant factor. Additionally, although the malware’s initial entry point was through this third party, Target needed to segment its network appropriately.
Proper segmentation prevented the breach from spreading to the business section and other network areas. Furthermore, due to flaws in the security system, the hackers could easily exploit backdoor usernames and passwords to gain control of three servers. Target also overlooked warnings from its antivirus programs and failed to secure its point-of-sale devices against unauthorized access. Despite having some protective measures like firewalls and a VLAN network, Target did not implement all reasonable steps to secure its data.
Target’s Response: The Good and Bad
Target failed to respond to several internal alerts, and the breach was only identified after the Department of Justice contacted them. Although Target’s monitoring software in Bangalore, India, had issued alerts, which were communicated to the Minneapolis staff, no further action was taken. Even with significant investments in security technology that included encryption, the attackers accessed the unencrypted data in memory.
Nevertheless, Target notified its customers about the breach approximately 20 days after it occurred and just four days after the breach was noticed. This response time is considered quick in comparison to many other data breaches. However, the breach highlighted the need for more stringent oversight of third-party solutions and an internal review of security protocols.
In response to the incident, Target introduced more secure chip-and-pin cards, recognizing that chip technology alone could not completely protect compromised cards. The incident also served as a learning experience for consumers, emphasizing that credit cards offer more security than debit cards, mainly because fraudulent transactions on credit cards can be reversed without immediate financial loss to the cardholder.
While chip-and-pin cards enhance security by requiring more than just cardholder information for transactions, the extensive data breach still left consumer identities at risk of theft, underscoring that identity theft remains a severe issue beyond individual card compromises.
How the Breach Affected Target?
The direct costs associated with the breach are estimated to exceed $202 million. This total includes the $18.5 million settlement that Target agreed to pay following a multi-state investigation, along with additional expenses for legal fees, further investigations, and efforts to prevent similar future incidents. Notably, the breach resulted in a noticeable drop in Target’s sales and impacted its stock value, with a 5.3% decrease in Q4 2013 sales compared to the previous year.
After the holiday season, customer caution increased as news of the data breach spread quickly. Target’s earnings reportedly fell by 46% after the attack, with significantly fewer households choosing to shop at Target. The company had to undertake significant efforts to rebuild its public reputation.
Lessons Learned at the Cost of 70 Million Customers’ Data
The Target data theft incident offers valuable lessons on enhancing corporate security measures:
- Conduct Regular Security Audits:
Security audits are crucial for assessing the effectiveness of an organization’s security policies. Post-target attack reflections revealed missed early warnings and potential security vulnerabilities. Regular audits help identify and mitigate these risks before they lead to breaches.
- Proactive Investment in Security:
The financial repercussions of a data breach, as seen with Target, can be substantial, including fines and lawsuits. Beyond immediate costs, the long-term impact on reputation and customer loyalty can be even more detrimental, necessitating significant investment to rebuild trust and restore the company’s image.
- Immediate Communication is Key:
Target’s delayed response in notifying customers highlighted the importance of timely communication. As soon as the news broke, Target should have issued immediate official communications via press releases, social media, and their website, indicating their awareness of the issue and their commitment to updating the public as more information became available.
They should have reassured their customers immediately that they were addressing the problem. Controlling the release of information helps manage the narrative and contain potential fallout. Delays can exacerbate customer frustration and damage control efforts.
- Employee Training:
Staff should be trained to recognize phishing scams and other cyber threats. A robust cybersecurity education program is essential for preemptive protection.
- Prioritize and Act on Warnings:
Organizations must treat security warnings with urgency. A well-documented cyber security contingency plan ensures that all employees know how to act swiftly and effectively when detecting threats.
- Network Segmentation:
The Target breach demonstrated the ease with which hackers can move from one section of a corporate network to another, highlighting merchants’ need to segment their networks. Hackers accessed Target’s POS system by stealing network credentials from Fazio Mechanical Services Inc., a vendor that worked with the retailer.
Proper network segmentation can also prevent the spread of breaches. Monitoring and validating all network traffic ensures that any unauthorized activity is quickly identified and addressed.
- Strong Password Policies:
Secure passwords are critical for protecting point-of-sale systems and sensitive equipment. Regular updates to password policies can enhance security.
- Develop an Incident Response Plan:
An organized response to security breaches can significantly reduce their impact. After the Target breach, many customers struggled to reach the company for information. A robust incident response plan addresses technical recovery and includes clear communication strategies.
