A look inside the complex logistics behind the Target hacks

Even though police have arrested two people in Texas who have used stolen Target credit card information, the hackers behind the breach will likely never be found, AP reports. The breach, in which 40 million credit and debit card numbers were stolen along with the personal information for 70 million customers, was likely carried about out by Russian or Eastern European hackers. These hackers are likely part of a complex heirarchy that keeps them several layers removed from the arrested card users. More →

Target data hack only the beginning of massive, sophisticated attack

The Target data breach may be just the tip of the iceberg in what seems to be a massive sophisticated attack on U.S. retailers that may have possibly originated in Russia, according to newly discovered evidence. The Wall Street Journal reports that federal and private investigators who are looking into the matter have discovered that parts of the malware used to hit Target has been available on the black market since last spring, and was written in Russian, leading them to believe the attack may have ties to organized crime in the former Soviet Union.

Neiman Marcus data breach went on for much longer than believed

The security breach at Neiman Marcus, which wasn’t acknowledged officially until a few days ago, went on for much longer than initially believed, the New York Times reports. While the retail store is yet to confirm to the public when the system was first hacked, it told credit card companies in a conference call on Monday that it all started in mid-July and that it wasn’t fully contained until Sunday, unnamed sources revealed. In its initial disclosure to the public, Neiman Marcus said it first learned about the breach in mid-December although it only decided to reveal it in January. In its notes to customers, the retailer said that key personal data, including Social Security numbers and birth dates, were not compromised. Furthermore, the company said that it doesn’t collect card PINs in its stores, and that it had “no knowledge of any connection” between the Target hack and the one it suffered. The retail chain is yet to reveal how many credit and debit cards were compromised during the attack. More →

Worried you might be among the 70 million Target breach victims? Here’s what you should do

This is a huge breach with obvious widespread implications for a shockingly large number of American consumers — 70 million represents more than 20% of the U.S. population. If you think you may be among those affected, however, there are some steps you can take to protect yourself. More →

Target: Yes, hackers got encrypted PINs along with stolen cards

Target on Friday confirmed that hackers managed to steal encrypted data including encrypted PINs, as reported by Reuters earlier this week, but added that the PIN numbers are still safe and hackers shouldn’t be able to use the information to compromise debit cards. According to the retailer, the PIN information is encrypted at the keypad and it remains encrypted within the system until it is decrypted only by the external payment processing company.

Reuters: Target hackers got encrypted bank PINs as well

The hackers who managed to steal data for up to 40 million credit cards used in Target stores on Black Friday and in following weeks have reportedly accessed the associated encrypted personal identification numbers (PINs) as well, which could be cracked and used to make fraudulent withdrawals. Reuters revealed the news in a recent report, which cited “a senior payments executive familiar with the situation.” However, Target says that unencrypted PINs were not accessed during the “sophisticated” digital heist and that there was no evidence that PINs were compromised, even if encrypted data that may have or may have not contained encrypted PINs was stolen.

A chilling start for the shopping season

According to National Retail Federation, shoppers spent about $1.7 billion less during the Thanksgiving weekend than they did in 2012. The sluggish weekend was anticipated, because Amazon and Walmart had started relatively aggressive promotions well before Black Friday. Nevertheless, the NRF numbers leave the fate of this winter shopping season very much up in the air. According to group, the number of people shopping either online or in the real world ticked up 1% over the last year’s period. But weekend spending dropped by a rather sharp 16 bucks to $407.55 per consumer. More →
