Target Car Gps

[Hildegard Mccauley]

Lastweek, Target told reporters at The Wall Street Journal and Reuters that the initial intrusion into its systems was traced back to network credentials that were stolen from a third party vendor. Sources now tell KrebsOnSecurity that the vendor in question was a refrigeration, heating and air conditioning subcontractor that has worked at a number of locations at Target and other top retailers.

Sources said that between Nov. 15 and Nov. 28 (Thanksgiving and the day before Black Friday), the attackers succeeded in uploading their card-stealing malicious software to a small number of cash registers within Target stores.

These were essentially compromised computers in the United States and elsewhere that were used to house the stolen data and that could be safely accessed by the suspected perpetrators in Eastern Europe and Russia.

It remains unclear when the dust settles from this investigation whether Target will be liable for failing to adhere to payment card industry (PCI) security standards, violations that can come with hefty fines.

In any case, Litan estimates that Target could be facing losses of up to $420 million as a result of this breach, including reimbursement associated with banks recovering the costs of reissuing millions of cards; fines from the card brands for PCI non-compliance; and direct Target customer service costs, including legal fees and credit monitoring for tens of millions of customers impacted by the breach.

Target may be able to cover some of those costs through a mesh network of business insurance claims. According to a Jan. 19 story at businessinsurance.com, Target has at least $100 million of cyber insurance and $65 million of directors and officers liability coverage.

Fazio Mechanical Services, Inc. places paramount importance on assuring the security of confidential customer data and information. While we cannot comment on the on-going federal investigation into the technical causes of the breach, we want to clarify important facts relating to this matter:

Like Target, we are a victim of a sophisticated cyber attack operation. We are fully cooperating with the Secret Service and Target to identify the possible cause of the breach and to help create proactive initiatives that will further enhance the security of client/vendor connections making them less vulnerable to future breaches.

Best guess for a company with around 2,000 locations and 360,000+ employees is it got dumped on a network segmented from the payment network but with wide access to their internal corporate network. That would remove the PCI 2-factor requirement and allow that RDP server to access the other AD resources it needs to perform its intended functions.

A classic PCI whitepaper from a QSA talks about how they owned the entire internal network from the Internet via a pen test undetected and in short order but found the PCI zone bullet-proof. Nothing they did would allow them to break-in and almost everything they tried generated an alert., unlike the internal network. Separate accounts, separate AD forest, you name it, they did it right.

With regards to the comments about whether yet another security product could have detected the intrusion I have two observations. These are not directed at the posters so please do not take offense.

I am not confident in what Avivah Litan states regarding PCI applicability, though her statement may have been taken out of context. Take a look at requirement 7 and 8 of the referenced PCI document; requirement 9 is applicable in a sense albeit it is regarding physicals access. Anyone who has done PCI DSS for an ASV (Approved Scanning Vendor) has read this document at least once in its entirety and references it often during certification and scans. Moving on, these requirements in PCI DSS (and other regulatory compliances) are difficult for an ASV to audit simply because a vendors word may be the only verification that is possible. We can make speculations and do finger pointing but ultimately it is the responsibility of the vendor to monitor and audit their own network and the individuals that have access.

After visiting Target yesterday, I became concerned after they scanned the back of my drivers license (which I believe is called a pdf417 barcode to comply with the Real ID Act). They did this because I did not have a receipt for my return. I understand that they are tracking individuals for fraud purposes, but why is all of the information on the license required?

Thank you again, JJ. It was indeed my fault for handing over my license. It was a deer in the headlights moment after realizing they were scanning the license, versus manually taking information from it. Well, lesson learned.

Great discussion. I did not see any mention of File Integrity Monitoring. PCI requires FIM to be in place and I was wondering whether this would have alerted that something was going on. Appreciate your thaoughts on this.

FIM will catch the dumb criminals. No good malware nowadays ever touches disk except maybe to store files in a system temp folder and nobody monitors a temp folder. If it never touches the disk, FIM is blind, deaf and dumb.

Thanks JJ. Given the increased sophistication of malware how do security practitioners defend against ram scraping attacks as it has been alleged to be the case in the Target breach. Is chip and pin implementation the solution? I believe that companies spend a lot of money to secure the perimeter of their network but ignore internal network security such as segmenting their networks i.e. a defense in depth approach. Plus running on old outdated technology make it easy targets for criminals.

Rupert asks how to defend from a RAM scraper. The answer is to encrypt at the swipe. Then you have to worry about the recent threat of hackers who substitute their device for yours, but this is easier than defending card numbers.

As far as I am concerned, the problem lies squarely with the processors. They have had end to end encryption for their standalone counter machines for many years, but they still drop the ball at the outside edge of the merchant network for POS based systems. There is no excuse for it, except that they are never the ones fined.

Would implementation of chip and pin and p2p encryption prevent such an attack? I have read that this attack would not be successful if the above was in place. Is this true? Does this mean that the data is never in the clear from start to finish of the transaction processing. Any feedback comments or information on this would be appreciated.

Thanks for your response JJ. EMV looks like the real deal along with p2pe encryption. Given that this is a very secure method of processing payments do we really need FIM if this is in place. I guess PCI will waive this requirement as well. I do agree with you that criminals will move to targets that are easier to exploit. A cop told me once that if you have a home alarm system installed burglars may just try a home without one and skip your home.

The RoC is submitted to the relevant card brand for their determination of whether it is acceptable. They can reject it or reject the compensating controls listed in it. They also can accept it as-is.

Target Corporation is an American retail corporation that operates a chain of discount department stores and hypermarkets, headquartered in Minneapolis, Minnesota. It is the seventh-largest retailer in the United States, and a component of the S&P 500 Index.[3] The company is one of the largest American-owned private employers in the United States.

The corporation was founded in Minneapolis by businessman George Dayton in 1902, and developed through the years via expansion and acquisitions. Target, the company's first discount store and eventual namesake, was opened in 1962. The company became the Dayton-Hudson Corporation after merging with the J.L. Hudson Company in 1969 and formerly held ownership of several department store chains including Dayton's, Hudson's, Marshall Field's, and Mervyn's. The parent company was renamed the Target Corporation in 2000. Despite the identical logo, name and similar type of outlets, Target Corporation is not affiliated with Target Australia.

The history of what would become Target Corporation first began in June 1902, when George Dayton purchased a company called Goodfellow Dry Goods. The company was renamed the Dayton's Dry Goods Company in 1903 and later the Dayton Company in 1910. The first Target store opened in Roseville, Minnesota, in 1962 while the parent company was renamed the Dayton Corporation in 1967. It became the Dayton-Hudson Corporation' after merging with the J. L. Hudson Company in 1969 and held ownership of several department-store chains including Dayton's, Hudson's, Marshall Field's, and Mervyn's. In 2000, the Dayton-Hudson Corporation was renamed to Target Corporation.

Target introduced the "PFresh" store prototype in 2008, which expanded its grocery selection in general-merchandise locations by upwards of 200%. Newly constructed stores that follow the PFresh format are roughly 1,500 sq ft (140 m2) larger than properties without groceries, although retain the Target branding because their offerings are considerably more limited than SuperTarget. PFresh sells perishable and frozen foods, baked goods, meat, and dairy. The company remodeled 109 stores accordingly in 2009, and renovated another 350 stores the following year.[13] The company's decision to close their garden centers opened floor space for PFresh expansion and larger seasonal departments beginning in 2010.[14]
