Global attack needed to catch credit thieves

Stopping massive data breaches like the one that hit Target will require a more sophisticated, collaborative approach by law enforcement agencies around the world, a Michigan State University cyber security expert argues.

In a new research report for the National Institute of Justice, Thomas Holt found many hackers and data thieves are operating in Russia or on websites where users communicate in Russian, making it easier to hide from U.S. and European authorities. All countries need to better work together to fight hacking and data theft campaigns, he said, and use undercover stings in which officers pose as administrators of the Internet forums where stolen data is advertised.

The Target breach, which comprised 40 million credit- and debit-card accounts during the 2013 holiday shopping season, may have originated in Russia, the Wall Street Journal recently reported.

"This is a truly global problem, one that we cannot solve domestically and that has to involve multiple nations and rigorous investigation through various channels," said Holt, associate professor of criminal justice.

Holt authored the 155-page report with Olga Smirnova from Eastern Carolina University. The National Institute of Justice funded their research, the largest to date on this crime, with a $280,000 grant.

Holt and Smirnova analyzed 13 Internet forums through which stolen credit data was advertised. Specifically, they found:

Ten of the forums were in Russian and three were in English, though the forums were hosted across the world.Visa and MasterCard were the most common cards for sale.The average advertised price for a stolen credit- or bank-card number was about $102.The average price for access to a hacked eBay or PayPal account was about $27.

Skilled hackers who steal thousands or even millions of cards generally attempt to quickly dump the data to buyers found through advertisements the hackers create in Internet forums. The buyers then assume the risk of making purchases or taking cash advances on the cards in return for a potentially large profit.

In the United States, Holt said it is imperative more money and resources -- such as Russian-speaking analysts and new technology -- be allocated to the FBI, Secret Service and other federal agencies to more effectively combat cybercrime.

Tougher state and federal cybercrime laws should also be passed to promote security and corporate responsibility. While 46 states currently require companies to disclose any loss of sensitive personal information in the event of a security breach, Holt suggested the laws generally don't go far enough to protect consumers.

"Greater transparency is needed on part of both corporations and banks to disclose the true number of customers affected and to what degree as quickly as possible in order to reduce the risk of customer loss and economic harm," he said.

Consumers also need to be more vigilant.

"There is a big need for public awareness campaigns to promote basic computer security principals and vigilance against identity theft," Holt said. "Consumers need to understand the potential harm from responding to unsolicited email and clicking on suspicious web links as well as the need to run anti-virus and security tools on their computers."

Romanian hackers busted with half a MILLION credit cards from Australia - how could THAT have happened?

Over 170,000 people are part of the Sophos community on Facebook. Why not join us on Facebook to find out about the latest security threats.

Hi fellow Twitter user! Follow our team of security experts on Twitter for the latest news about internet security threats.

The Australian Federal Police (AFP) are cock-a-hoop this week, announcing the bust of a gang of Romanian credit card hackers.

According to reports, 200 Romanian cops pounced on 36 locations, detained 16 people and ultimately arrested seven of them.

The carding crew had allegedly made off with half a million Aussie credit card numbers, racking up charges averaging more than $1000 each on 30,000 of them.

At this point, I'm sure you're thinking what I am. "Half a MILLION cards from Australia. And the crooks didn't even need to leave Romania. How could THAT have happened?"

The answer, according to the Australian cops, is RDP.

Remote Desktop Protocol - or Routine Darkside Probe, as we dubbed it in a recent article advising you on how to secure it - is Microsoft's solution for remote administration of your computers.

RDP effectively mirrors the screen and keyboard of a remote system on your local device.

Move the mouse in the RDP client, and it moves on the remote system. Pop up a software dialog on the remote system and the screen updates are mirrored on your local desktop. It's almost as good as being right there.

Leaving RDP open to the internet is therefore a little bit like giving a visitor a seat in the corner of your server room and saying, "I'll just leave you here while I go for lunch. Don't touch anything, will you?"

In this case, a bunch of small Aussie retailers were targeted. It's not clear whether the hacking took place via IT infrastructure they all shared (a so-called cloud), so that the crooks were able to penetrate everyone in one shot, or if each retailer was probed and hacked individually.

Once you've got an RDP connection to the inside of a network, you can run pretty much any software you like, even GUI-only applications that weren't built with remote control in mind.

It seems that's what the crooks did, running up the retailers' Point of Sale (PoS) software and retrieving credit card numbers already collected by the retailers' own payment devices.

We've written about skimming a couple of times recently.

That's where you add a covert credit card reader in front of a real one.

Any card swiped or inserted gets read in twice: once by your data-siphon and once by the genuine device. Loosely speaking, you steal the card data individually from each card.

In this hack, the hackers didn't even need a skimmer. They let the official card reading devices handle that job, and stole the credit card data in bulk - straight from the horse's stomach, if you don't mind mixing your mixed metaphors.

The problem with this sort of hack is that there is very little consumers can do to protect themselves.

All the advice you'll hear about choosing decent passwords, wiggling the card slot to look for tampering, and avoiding phishing emails that invite you to initiate an on-line transaction? Those won't help here.

You can do everything right, but if your retailer - or your retailer's IT provider - does the wrong thing, invisibly to you somewhere in the back of the network, you may never know until it's too late.

(That, my friends, is why we need mandatory breach disclosure laws: so you can keep current with what's happened to your personally identifiable information.)

The take-aways from this story?

• If you're a cybercrook, the fact that you're sitting far away in a different jurisdiction makes it tougher for the cops to nab you. But not impossible!

• Don't leave RDP open across the internet. It ends in tears, for you and your customers.

36 websites selling credit card details shut down [VIDEO]

Over 170,000 people are part of the Sophos community on Facebook. Why not join us on Facebook to find out about the latest security threats.

Hi fellow Twitter user! Follow our team of security experts on Twitter for the latest news about internet security threats.

Cybercrime is big business these days, in fact it's an industry. So it's not a surprise to find that criminals are embracing ecommerce. But I'm sure some will be surprised to discover just how professional and legitimate criminal websites can appear.

For instance, watch the following video to see footage of a website that was selling stolen credit card details.


(Enjoy this video? Check out more on the SophosLabs YouTube channel.)

The UK's Serious Organised Crime Agency (SOCA), working alongside the FBI and the US Department of Justice, has announced that it has seized the domain names of 36 websites used to sell stolen credit card information.

Searching for stolen credit card details

The websites use advanced e-commerce Automated Vending Cart (AVC) platforms to allow them to sell large numbers of credit card and bank details.

Visitors to the websites are now greeted by a message from the authorities:

Law enforcement message

According to a SOCA statement, two men were arrested early yesterday morning suspected of making large scale purchases of compromised data from websites such as those described above.

In addition, the UK’s Dedicated Cheque & Plastic Crime Unit (DCPCU) has seized a number of computers suspected of being used to facilitate Fraud Act offences, and an AVC operator based in Macedonia has been arrested by the Macedonian Ministry of Interior Cyber Crime Unit.

We should all be grateful that the authorities are taking action against those who are turning cybercrime into such a significant underground industry.
