Target Security Breach in 2013


The main point to be covered in this discussion is the Target Corporation security breach that took place in 2013, which affected customers who swiped their credit and debit cards between Nov. 27/2013 and Dec. 15/2013, and became a very important topic in network security. This security issue was announced via a report written by the security researcher Brian Krebs, who published that Target had suffered a data breach and the customer’s card information was totally exposed and unsecured in 2013 (CNN Money, 2013).

About the Company

Target Corporation is the 2nd largest American retailing company having revenue of $72,596 in 2013 and taking the 29th place in the ranking on Fortune’s World Most Admired Companies List (Target Corporation, 2014).

Affected and Impacted Customers

The main fact is that in 2013 about 40 million credit and debit card information stored in the Target Corporation computers, was stolen by hackers and this information was used by bad-intentioned users, who possibly would use this information for self-benefit.

Technical Information and Causes

To understand a bit more about it, security experts said that hackers targeted the point-of-sale system, maybe infecting those computers with malware in the terminals or possibly collecting the data on route to the credit card processors (CNN Money, 2013).

Specialists said that the main problem is the obsolete technology used in American Credit and Debit card transactions. Comparing to the technology used abroad credit cards have a chip that creates a unique PIN for the transaction and is also more difficult to clone, different from the technology used in the USA, which the magnetic strip could be easily duplicated.

My personal critical thoughts

With my experience on developing software, first, a big mistake is probably the technique of storing the complete user’s credit card information since it is not necessary because there is the possibility of storing only a part of the credit card number and ask the user to fill it when necessary, so I would never encourage storing all the card information at any computing resource.

Based on my findings I can conclude that the main reason all the information being stolen is the use of obsolete technology not only in Target Corporation but also by all the American companies that use credit card related operations.


Computer security cannot be guaranteed with the kind of technology we have nowadays especially when we considering networks, which data can be intercepted and you do not have control to where this is information is being transferred and stored.

The Target Corporation case became very popular on the news, but this kind of security breach occurs frequently on the Internet and so much information is stolen every day, nevertheless, it is possibly never come to the news.
